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.
