Digital battery

Battery frost and key technologies:

 

1. The main raw materials of design calculations, selection and matching

2. Gel batteries special plate design, formulation and manufacturing process

3. Colloidal formulation and preparation, the dispersion SiO2

4. Early loading or filling operation

5. New gel batteries for added power technology

 

1. The main raw materials, design calculations, selection and matching

 

Gel batteries, the need to report the positive and negative electrode capacity, the thickness of the partition size, plastic shell the size of support, including IBM ThinkPad T60 battery capacity and the plastic shell size of single cell the relationship between the parameters corresponding to a series of reasonable arrangement. In general, single-cell battery should be able to guarantee an effective space filling of acid amounted to 12-15 ml / AH to protect the battery in the amount of the effect of the adjustment of acid-containing gel.

 

A common problem is the use of sealed AGM batteries the standard plastic shell to act as a shell plastic gel battery, which is often caused by insufficient capacity or the battery open circuit faults in voltage and other issues. Another problem more common in domestic PE separators such as the use of private partitions instead of gel batteries, or use a sleeve of fiberglass, silk short sleeves instead of polyester gel battery box Dedicated partitions, which are most seriously affected product, life makes life / cost, but not worth the candle.

 

Users demands long battery life expectancy colloid required in the design and equipment selection, when it should be more stringent than the conventional design sealed Dell Latitude D520 battery, seal the pole to the growth and expansion of plate boundaries, etc., required in the structure must be considered and there should be corresponding measures, such as strength and size of pads and linings using a special pole structure, and enough interior space.

 

It is worth noting is how to prevent the assembly process in the break and short circuit group to protect the qualification rate of finished product.

 

2. Colloid plate special battery design, formulation and manufacturing process

 

Private plate gel batteries in particular, positive plate, and plate sealed classic comparison of the battery must be adapted to gel batteries (electrolyte) Special Requirements:

 

A, the requirements of colloid infusion: making the electrolyte in the hp F2024B battery is full all the corners;

B, to eliminate the polarization resistance increases due to the uneven increase in effect, require grid support structure design reasonable, hob, drying process reasonable and practicable;

C, regardless of recycling or floating charge to use, require long life, there is no thermal runaway phenomenon;

D colloidal form a network structure on the plates and separators and opening requirements of the porosity;

E, moreover, the actual conversion time of the battery in question.

 

3. Formulation of colloids and preparation process, SiO2 dispersion

 

A, first of all, is a gel battery needs to know the problems that the sony VGP-BPS2A battery needs to determine colloidal properties.

 

Council of the battery positive and negative active material in the electrolyte, after infiltrating the structure, you can get some inspiration.

 

Contrary to watch active substances of the structure and composition changes in the electrolyte after injection, the active material and electrolyte combination of regional, living matter was crystal - colloids (crystal structure of the glue) , sulfuric acid and water can freely enter the active substance through the diffusion of network structure of the territory, but the plastic changes of crystal structure depends largely on living material (lead dioxide or metal ) and lead sulfate (sulphate) conversion, while the sulfuric acid and water, and generate little to do with the reduction or can not be because the sulfuric acid or water to increase and decrease in moisture or frost. Therefore, life can always keep the stability of the structure. Thus, it can analogy to say that the sulfuric acid and water in the role of colloids: In the additive in the plastic front, followed by injection in the plastic, but should not be the structure of colloidal constructions.

 

Previous studies, often the chemical transformation of silica hydration —- begin to draw on the reversible reaction of water glass to understand the mechanism of the colloidal structure, and it is very easy to stick on the glass water and other resources, and even the two Silica gel hydration is a key step.

 

In fact, if the set colloidal structure of sulfuric acid and water are the structural components, toshiba PA3285U-2BRS battery charge-discharge process in the corresponding chemical reaction caused by sulfuric acid and changes in the composition of water in the original colloidal structure will inevitably lead to fragmentation, collapse and reorganization, the correspondent must gel hydration and shrinkage. It is difficult to say that the battery life to meet the needs of a stable structure. Therefore, this myth should not be allowed to continue.

 

After that, we had an aging test (after festivals worldwide after the battery charge-discharge cycles, the crack formation) and gel batteries to overcharge and over discharge to verify this conclusion, a mainstream (0.2C to 0.3c) conducted on a full charge of battery power (1.5C to 3.0C), or excessive discharge and closing terminal battery voltage to 0V (discharge volume reached 1.2C to 1.5C, and even more). These experiences, we can see (police) for gel batteries warm, but we see no moisture to freeze.

 

B, the gel formulation and preparation, the more critical is the dispersion of silica. Not studied ultra-fine powder or knowledge, it is difficult to understand the dispersion of the dispersion of silica rigorous requirements. The ultra-fine powder technology in the industry of household batteries are not very partial knowledge of point to study the dispersion of silica dispersed in water is almost pitiful papers, research focussed mainly in paints, etc. Hang Dang.

 

C on silica thickening and thixotropy awareness, in particular, recognize that the thickening of the silica and thixotropy are not inalienable, a process of inappropriate preparation could affect the silica thickening and thixotropy. Right filling process of plastic production, the thixotropic gel is very important, but the life of the apple iBook G4 14 inch battery in the finished product, the colloidal thixotropic Zexu eradicated.

 

D, training battery, and the plate pairs of colloidal have different needs, a corresponding change in the colloidal components.

 

4. To start charging or filling operation

 

Many people are beginning to charge or recharge the battery capacity as a simple process to adjust and active substances in the process, prefer to be adjusted according to their understanding of recharge processes. In fact, the process of loading the gel battery is just a hammer 100 to 1000 the training process, each side in the process of loading and unloading steps is mutually reinforcing.

 

Enjoy the cooking equipment plate, the initial charge of battery for a complete charging process must address the following questions:

 

A plate active material fully translated to protect the battery capacity;

B, plate active material of structural adjustment in order to form a relatively homogeneous and colloidal;

C, reaching the original glue and sulfuric acid, water exchange, the formation of uniform colloidal structure, fully utilize and improve colloidal thickening, reduce the thixotropic gel to form a stable colloidal structure;

D set the Dell GD761 battery voltage and capacity, to adjust the consistency of the battery (capacity, resistance, voltage, etc. coherence).

E, charging additional water loss and water temperature control, and so on.

 

5. The new gel batteries add power technology

 

The new gel batteries, the aging treatment are not a new battery, because not yet formed cracks. Therefore, in the charging of fees to certain requirements.

 

Unreasonable electrical process may be more intense mixing effect, undermine the stability of the colloidal structure, hydration, once produced, it undermines the performance of colloidal thickening. After charging, it is easy to create a localized or overall hydration, this is a very serious damage to the gel, and it will significantly reduce the lifespan of the battery.

 

Stockpiles new gel properly shelved is also aging, can form cracks.

 

How the new batteries with gel methods are most rapid economic and environmentally sound treatment in the aging of the battery that is worth seeing.

Rechargeable Ni-MH battery how long charge

 

Depends mainly charger charging current is really spacious. Take note of the charger output current above, for example, 500mAh, 2000mAh Laptop battery should charge for four hours, then add a drizzle of extra hours. This is usually rapid battery. There is also a slow 100-200 mAh rechargeable empathy with the size of the battery capacity divided by the output current can be drawn.

 

In addition, Ni-MH battery memory effect the battery is relatively low, but not the representatives are not, so the best time to recharge completely discharged, then charge. If it is in the use of the battery, then obviously do not use electricity, such as MP3, uses no power of nature will be arrested and charge re-born. This helps prolong life.

 

The use of lithium-ion battery

 

1, how to charge the battery in use for a new lithium battery should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shortening. However, lithium batteries can easily activated, as after 3-5 times the normal charge-discharge cycles the IBM ThinkPad R51 battery can be activated to restore normal capacity. As the characteristics of lithium, its decision is almost no memory effect. Mobile phones so that users of the new lithium battery in the activation process does not require methods and special equipment. Not only is the theory that, from my point of view practice from the start on using the standard method of charging that “activation” is the best approach. For the lithium battery “activate” problem, many say, is the cooldown should be longer than 12 hours, three times in order to activate the battery. This “The first three load over 12 hours to charge” was obviously the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that the beginning a miscommunication. Lithium batteries and charge the battery nickel and discharge characteristics are very different but also very clear to you that I have gone through all the serious official stressed that the technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion causing major damage. According to the standard load and therefore the best time and the standard method of pricing, in particular, do not make more than 12 hours of ultra-long burden. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of pricing. In addition, cell phone batteries or lithium charger stops automatically when the hp 361742-001 battery is full load, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white horse is also sufficient. And we can not guarantee that no one battery charge and the circuit characteristics of discharge protection and will never change and the quality of the safety device so that your battery will be of long duration space flight hazard. It is also d ‘another charge against the main reason. In addition, in some mobile phones, charging more for some time, if they do not remove the charger, this time not only to stop charging system will start to discharge — charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that the battery and cell phone / charger is detrimental in terms of life expectancy. Meanwhile, the charging time should be some time, often at night, but our situation to the electricity grid at night in many places, over voltage, but also volatile. As already said, the lithium batteries is very precious, and more that nickel in the electric charge and discharge aspects of fluctuations in the resistance is much less, if this brings additional risk. In addition, another aspect can not be overlooked is the lithium toshiba PA3285U-2BRS battery is not not appropriate for excessive discharge, excessive discharge of lithium batteries is also very unfavorable. This leads to the following questions.

 

2, normal use should be time to start loading in our forums, often see this argument, because the number of charging and discharging is limited, so phone, the battery should be used as much as possible recharge. But I found one on the charge of lithium-ion battery and Table discharge cycle test, data life cycle is as follows: life cycle (10% DOD):> 1000 Once the life cycle (100% DOD):> 200 times DOD is the rejection of which depth abbreviation. Can be seen from the table in May of depth charge and discharge times, 10% DOD cycle life when the DOD of 100% for much longer. Of course, if the equivalent of actual costs to the total capacity on 10% * 1000 = 100100 * 200% = 200, one full charge and discharge, or better than some, but not before friends say some changes: Under the normal case, you should have a standby battery power is left in accordance with the principle of charging the short load again, but if your battery in your first two days can be expected to persist throughout the day, when they should start on time charge, of course, if you’re willing to back the charger to the office again a different issue. And you need to recharge in order to cope with the communication provided lead busy to come to an important event, even if a lot of apple A1022 battery power over time, then you just charge ahead, because you don ‘are not really lost, “as a” life cycle support is “0.x” times only, and that x is often very low. Short on battery and then filling the rest of this principle is that you want to go to the extreme. And long as charging a widespread view that “as far as possible the cell phone battery power runs out, it is preferable to use automatic shutdown.” It’s really just practice for nickel, the goal is avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It was too low because the cell phone battery warning appears, still do not charge to continue using the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the answer no, should provide review services to clients. In fact, it is because of the battery caused by excessive discharges of electricity at low voltage, so that was not the normal load and footwear and conditions.

 

3 phones for lithium batteries good way to sum up, I lithium batteries used in mobile loading and unloading, the most important recommendations are: (1) in accordance with standards and procedures, charging time, even the first three have to do, (2) when it is weak advice cell phone battery, you should try to start charging a timely manner, (3), lithium batteries do not need ‘ enable the special mode, a battery of standard cell phones use lithium is naturally activated. If you insist on spreading the use of “three previous 12-hour long activation charge” approach, in fact, there will be no effect. Therefore, the pursuit of all super-long 12-hours lithium rechargeable Aspire 3000 battery cell phone use and integration of the practice of automatic shutdown, are wrong. If you’ve already done under the argument wrong, please correct time, perhaps not too late. Of course, cell phones and chargers to protect themselves and the circuit control for good quality, protection of lithium batteries is still guaranteed. Therefore, the burden is central to understanding the rules and, in some cases also may make some concessions. For example, you find your cell phone the night before bed charge, you can also start charging before going to bed. knot of the problem, you need to know what good thing, and not deliberately wrong to do so in accordance with.

 

Battery Maintenance:

 

We know that the cell phone apple A1060 battery is a source of electrical energy, which is the driving force of mobile phone, there is no mobile phone battery is one piece, high capacity, high performance batteries, not only for cell phone long battery life, but also protect telephone circuits to devices that can operate effectively a long time, and vice versa, is likely to cause unexpected damage to mobile phones. For us players, the performance of the battery when the factory, it had already been determined, the size of its capacity, performance, good or bad, are determined by the cell itself and in this regard, we can not man-made changes, but this does not mean that we get the battery after it has produced it should not be done. The use of mobile phones are lithium-ion rechargeable batteries used to store electricity is consumed, need to be added once the feedstock. Do not look down on charge of this aspect of a good shipper and the correct method of load can keep the battery long wait time, but also extend battery life. No more, says mobile phones can also play a protective effect.

 

Methods on how to charge, often in the forum, players will be invited, after a period of actual use and reference, I have summarized the following points:

1. Lithium general factory, manufacturers enable the processing and pre-charge the batteries have more than electricity, you can buy a new cell phone battery is a lithium-ion toshiba PA3285U-3BRS battery, then the first 3 to 5 times charged as a period of adjustment, should be sufficient for more than 14 hours to ensure complete activation of the lithium-ion activity. Lithium-ion battery without memory effect, but a strong inert, should be given to fully activated to ensure that used to achieve best performance. The first charge on this issue, I also consulted the technical staff of Samsung gave me the answer is Samsung original battery, the factory has already been done before the full activation of the treatment, then it does not a long way to activate the charging lithium-ion activity, the first rechargeable battery inside as long as I can be filled after the consumption of electricity. I would like to Samsung’s technical staff should be able to claim convincingly.

 

2. Some automated intelligent rapid charger when the lights change direction, but only said he was full of 90%. Charger will automatically change with the slow loading of the battery is full. Do not immediately cut off the charger, the best should be given to supplement the battery for a while, the battery is fully charged before use, otherwise it will shorten the duration of use. 3. Before charging, lithium batteries do not need to assume, can not fulfill the current production of hp F2024B battery charger lithium is impossible to perform functions, so you can adjust the speed of loading, then suggest that you try to slow Chong Chongdian pricing to reduce the fast charge mode: either slow or fast charge fee of more than 24 hours. Otherwise, the battery is likely to spend long hours of power have an enormous flow of electrons and burning batteries.

 

4. There are many users in charge when the phone open, in the process of charging, the battery side because of the use of mobile phones in landfills, and also because the battery while the assets of Supply disruption of power supply is likely to result in the councils of cell phone circuit will be fever, if an incoming call will result in an instant return current to damage the internal parts of the phone.

 

5. Battery determined by the number of repeated charge-discharge, lithium batteries can continuously charge and discharge of about 500 or so after the battery performance will be significantly weakened, and must try to avoid all batteries I put an end to the rechargeable power, or with the load increase in the battery performance will gradually weaken, the battery reserve time it would be difficult not decreased.

 

6. Do not expose the battery to heat or cold, as a day dog should not be placed on a mobile phone under the sun, and withstood exposure to hot sun, or get air-conditioned room, the air conditioning blowing right places. Loading, the current return, the battery a little fever is normal.

 

7. If the mobile phone battery to attach too long without employment, it is best to call the maintenance department to apply on the drums for an activation treatment, you can own devices with a constant voltage direct current, by adjusting the voltage of 5 ~ 6V, current 500 ~ 600mA reverse battery connector. Note that the liberalization of touch, most can be repeated three times, after such treatment, re-use original charger “adjustment” charge.

 

8. The higher the load is not good, not protecting the circuit fully charged battery must be stopped immediately, otherwise they will have an impact on performance due to fever or overheating. Theoretical calculation of IBM ThinkPad R52 battery charging time is as follows: power battery charger, divided by the output current can be, for example a 800mAh battery, for example, the charger output current 500MA, then the time load is equivalent to 800MAH/500MA = 1.6 hours, of course, this is a theoretical calculation of time is full of power, while the charger shows charging is completed, preferably about half an hour or and should be given to the size of the battery power-up time. Dedicated lithium-ion battery charger must be selected, or they may not reach saturation, the impact on its performance.
