Li-maintenance errors ion battery doubts

 

Notebook battery is something more important, its status is directly linked to a mobile environment in the absence of power in the ability to work. Batteries for laptops is also a major consumer of parts so related to the maintenance notebook battery and wise use are also frequently discussed topic. However, some users maintain some of the understanding is wrong, the following should do something to explain. apple iBook G4 12 inch battery  apple iBook G4 14 inch battery

 

Nickel-metal hydride batteries are now equipped models have basically will not see, the universal application of a lithium-ion batteries. General lithium-ion battery cycle life of 300 to 500 charge-discharge. But this does not mean it can only rarely use the extended life battery. Cells of origin as factors in the physical work environment can influence, but the main reason leading to the loss of cells caused by oxidation of the battery internal resistance increases, which explains why Many users complain that they are fully recharged in use why suddenly had no electricity. It may therefore be understood that the problem is that when the end of the assembly of the battery production line, its internal life, the clock, then start walking, even if you do not set aside the battery, it can be to a certain extent, the loss rate of only delaying the battery. However, in other words, if the battery still sits on the side of the meaning of laptops mobile speak?

 

Material for lithium-ion battery cathode is generally formed by a lithium-active compounds, the negative electrode is a particular molecular structure of carbon. Common Cathode Material for key elements of LiCoO2, charging, added to the PA3285U-3BRS PA3383U-1BRS battery positive pole of electric potential to force the release of compounds, the lithium ions, incorporate negative elements arranged in a lamellar structure of carbon. Discharge, lithium-ion lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current. Although the principle of chemical reaction is very simple, but in actual industrial production, the practical problems must be considered much more: the cathode material additives required to maintain multiple load-discharge activity, the electrode material If not, who should design the molecular structure of the class to accommodate more lithium-ion battery; fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the resistance of the internal battery.

 

Although lithium-ion batteries for low-nickel cadmium battery memory effect, the memory effect of this principle is that the crystallization in lithium batteries will have little reaction. However, the capacity of lithium-ion battery charge after repeated discharge will continue to decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ions on the hole to accommodate the structure will gradually collapse, taken from a chemical standpoint, is the material anode active is passive, there is another side to form a stable compound. Physics will appear on the cathode material to fall off gradually, etc., in short, which ultimately reduces the 346970-001 367759-001 battery charge-discharge process can be free to move many lithium ions.

 

Overload and excessive discharge, lithium-ion batteries will be positive and negative cause permanent damage, from the molecular level of intuitive understanding, an excessive discharge of carbon anode will lead to excessive release of lithium-ion shows the lamellar structure collapsed, over - Rechargeable lithium-ion battery will go too hard in the carbon negative, causing some of the lithium-ion batteries can not be released. Therefore, the lithium-ion batteries are usually equipped with charge-control circuit discharge.

 

Not suitable for temperature, lead to lithium-ion battery inside the reaction of other chemicals that we do not want to see both of the lithium-ion batteries are put in place between the negative temperature-controlled protection by a diaphragm or electrolyte additives. In the battery temperature in a given case, the composite membrane electrolyte membrane hole closed or degeneration, increased resistance of the internal battery until the circuit, the battery is no longer to warm up to ensure that the battery charging temperature is normal.

And loads of deep-discharge lithium-ion batteries can improve the real capacity? According to experts, the answer he did not make sense. Experts say that even the so-called triple full charge-discharge prior to use of “activation” in their knowledge of Mr. Lane does not include this as a need. Why do people provided, however, after the charge deep-discharge capacity of the battery information label will be possible where a change? Will be mentioned later.

 

Notebook Computer lithium-ion batteries are generally the management of the chip and chip load control. What chip running a series of records, there is capacity, temperature, identity, charge state, the values of firing rate. These values are in use will gradually change. Personally believe that the instructions for use in notebooks in the “Use a month should post a full load” approach to a role is now to set those records where the wrong values, making the burden of Battery control and the nominal capacity of the battery match the real situation.

 

Responsible for controlling the main control chip, the battery charging process. Lithium-ion battery charging process is divided into two phases, phase constant current fast charge (when the LED on the battery in yellow) and constant voltage stage down (the battery indicator blinks green. Constant current phase of rapid charging, the battery voltage is gradually increased voltage standard battery, and then transferred to constant pressure in the control phase of the next chip, the voltage does not increase to ensure that no overload, battery current, with the rising gradually weakened to 0, and the ultimate end load.

Statistics smart energy consumption by recording the discharge curve (voltage, current, time) can calculate the battery power of the sample is what we read in the battery information inside World Heritage. Worth. The lithium-ion batteries in repeated use, the discharge curve will change if the chip has not been an opportunity once again read out a complete discharge curve, which is calculated from the electricity that is not true. Therefore, the need to support deep discharge to calibrate the battery chips.

 

A good battery maintenance is required, so many people have asked how to protect a battery but it will not be early retirement for life on this problem. As the battery life is primarily determined by the number of charge cycles in order to avoid frequent use of the battery can be said that one of the most fundamental way, that uses the power of the environment as far as possible does not use batteries.

 

This leads to a question, that is, if energy use when the battery removed from the machine, it is indeed a problem that people in the head. However, the condition of high load and high temperature accelerated the decline in battery capacity. I now invite all imagine that if you do not remove the battery, the laptop because of the role of the charging protection circuit, so that the battery is maintained at 95-100% of the charge state to a high when the battery in which the temperature at least 30 ° C, so if it is hot, the temperature will be higher, so the stability of the supply alternating current, we should try to remove the battery to the using computers. If you are planning a long period does not use batteries, charge the battery to 40% should be placed in a cool place after the save. If the battery is fully charged, will be placed at high temperatures, so that the battery will cause damage. Because load of 100% within 60 ° C environmental conservation, 3 months after the battery capacity has dropped by 40%. Set aside for the preservation of the battery should be at least one month will be used once the battery Zhuangshang Qu, recharged to prevent the loss of activity of the ion.

Similarly, dust and moisture also acts as a battery killer role, they will destroy the circuit of the battery and accelerate the oxidation of the internal battery, so for those of long-term preservation of the battery You can place a layer of thin sheets of low-grade dust and breach of the humidity.

 

In addition, lithium batteries how reasonable prices and dump? As lithium-ion battery that can power a small memory effect is negligible, so it loads half of the injury is not too great, and his fear most is the excessive discharge (full discharge). Lithium-ion batteries often the result of low flow excessive battery can be left in advance, such as bios discharge, discharge procedures, and even connected to the discharge bulb is the best way to do see no alternative but to not try. So, for lithium-ion batteries need not wait until the charging 0%.

 

To summarize, the maintenance of the battery are a few suggestions:

 

1. No need to ensure that whenever a new full release END electric charge;

 

2. A period of time to make a protection circuit placed under the control of the profound power of the battery charge to change the statistics, but it will not increase the actual capacity of the battery;

 

3. A long time without the battery must be placed in the shade to weaken its internal autonomy, the reaction rate passivation;

 

4. Protection circuit is also capable of monitoring battery discharge, in the long term without the battery must be charged to a certain degree of power to prevent self-discharge of batteries for storage in the discharge of excessive lead to excessive damage to the battery.

 

In fact, there is not much to take into account the use of the battery of attention, in other words, is the need did not have much effect. The number of times a cell can use the differences are mainly coming from the battery itself, the making of individual differences rather than use. Choose a reputable brand of notebook PCs is the use of long battery life in the only future of the security.

Color screen phones has been the market for a full year, advertising overwhelming, tempting us to the rope, but users still can not calmly why buy? The high prices of the reasons are undoubtedly important, but also a problem in the cell phone batteries can not shirk responsibility.

 

According to statistics, almost half of users suspected cell phone battery standby is too short, through a series of problems for users, so that the user “love machine is not easy. “

 

Bacheng users more satisfied with waiting time for a more detailed understanding of the thinking of the user, a recent study of Saint-Marc, Beijing, Shanghai and other major cities between the ages of 20 — 40 mobile phone users completed a survey on male / female ratio of the sample 6:4, close to the real market rate of the user.

Asked about “the mobile phone battery current satisfied, the 79% of users are the views of batteries for mobile phones. Knowledge of Figure 1, only 13% of satisfied users of mobile phone batteries, 8% of people Generally, he reluctantly accepts.

 

User comments on the current number of batteries for mobile phones, mainly summarized standby, performance and appearance in three areas (see Figure II). Firstly, 37% of respondents think the waiting time is too short, they believe that the frequent travel and preparation of back-up battery is charging something inconvenient. Secondly, approximately 19% of people said that nothing guarantees the performance, especially the numerous non-original batteries are more prone to problems, life is even shorter. Again, almost 15% of respondents believe that the battery color machine as a whole can not meet the multimedia, gaming and other multimedia needs. Finally, he expressed aspect is larger and lighter mobile phone form PA3534U-1BRS PA3591U-1BRS factor may not be consistent.

 

According to the sales staff of mobile phones, in the absence of words or short message service, waiting time traditional phone is generally 5 days, the actual use of generally three days, for traffic management or Sales of such personnel shall normally not exceed 2 days. In fact, users generally think that it would not be enough time before the battery market as a whole is even shorter time saver.

 

Compared to the previous two years, and now the market for mobile telephony is already sitting on top “Gold Mountain”. With the technical threshold for the reduction of accessories for mobile phones by the coveted “Wedge Mountain” Small and Medium Enterprises swarmed the market while a mixed bag. As these manufacturers to pursue “low cost” and “factory fast” quality batteries for mobile phones, there is no assurance that the natural reduction of standby time, the batteries gradually increase market share throughout VGP-BPS2 VGP-BPS2A Battery standby is short.

 

At the same time, these non-original batteries are still quality assurance and after sales service for the user to add a lot of trouble, leaving the poor impression. In this regard, a user is full of grievances: “Suddenly a problem, you must go to repair, the warranty can not find the person can go to the expensive mobile phone accessories shop slaughtered.”

 

At present mobile phone standby time has become a headache for the business traveler. Especially those who travel long business people moving frequently, the sales staff, they have more time to load their regular cell phones, let alone mobile phone charging much more time “meal” for finish things. This obviously gives “busy” as the characteristics of a mission to carry a heavy burden.

 

Recent salary survey shows that domestic: in all trades, marketing or sales revenue ahead of the fourth class of employees, what is channel sales business and an increased awareness with the result. Company management is probably the high income group, have lost these two groups of users, the positioning in the high-level consumer machines depend on the color of Han to eat? Traditional cell phone will lose a cow. PP2182L HSTNN-LB31

 

Users look forward to “green” and not “undisciplined”

 

To the user of mobile phone battery has a lot of comments also expressed a degree of understanding and of the ardent expectation of all respondents were willing to express their views on the future of batteries for mobile phones (see Figure 3).

 

When asked “Are you the best hope for the future of batteries for mobile phones,” haste the battery more environmentally friendly was the largest, representing about 33%. Environmental protection is consistent with modern trends in green consumption, the result of this, Toshiba has taken a position, recently launched a battery more environmentally formaldehyde, it is understood from the consumer market, batteries lithium, this new type of battery is also more durable advantages over thin. Has been followed by nearly 23% of applications in both large capacity, good performance and the advantages of small form factor. This fuel cell technology, if necessary, the “mad rush”, which is for manufacturers to invest in more R & D devoted more energy, government support for multi-point test market time points. Mobile Home for technical faults, Wang Bing, deputy director of the Ministry of Information Industry Bureau is running emphasized: To reserve 3G industry, technology, Ministry of the Information Industry will increase in future 3G mobile phones, product development, investment, focus on breakthroughs in core technologies and software technology.

Some users even consider problems from the perspective of manufacturers. An older man said: “Due to a variety of reasons, manufacturers of mobile phone technology is not enough rainfall, especially the domestic manufacturers is very difficult to function and appearance are perfect. ” 16% of people make greater investments in technology consulting also mentioned that some people in front of the battery can not be the trend of compact mobile phones online for concern.

 

Understanding the ownership of understanding of the user is still hope that the future of mobile phones easier to use. 28% of respondents have raised a number of questions about the use of small areas. These problems may companies do not realize that, but quite reasonable. About 13% of people want companies to effectively carry out the “Three Guarantees” service commitment, 12% of the charger a few questions like “Why is the make or model of mobile phone charger can not be reunification ? “,” head load device ‘Why so many “hands up”? flashboard occupy too much space, “… … or even 3% of people do not stop for replacement batteries and so on. An argument is more direct: “Do not the manufacturers of cell phones can do so many batteries and chargers” undisciplined “?IBM ThinkPad T42 battery IBM ThinkPad T43 battery

 

Users and a variety of nuanced understanding of hope is that the cell phone as a consumer mass was close to everyday people.

 

As the lives of some, but you also need to intimate service. However, users still lack the “three guarantees” service. It is understood that, “Three Guarantees” service after the enactment of the majority of the officers of “three guarantees” as stipulated in more clearly, but not implemented, the rate of cell phone complaints remained high. The frustration that some users’ mobile phones parallel “does not generally have after-sales service, it is difficult to accept that formal activity staff mobile phone service often with” water “, etc. as an excuse” three boxes of “services”. “Many manufacturers maintain a variety of points that we consider hidden costs of fraud.”

 

Just think, if you forget when you travel with a charger because the charger can not “step in those shoes, you have to offer cell phone service pricing for finding hotels, shopping malls, and even borrow charger strange companion, which are clearly unnecessary trouble. Pay attention to the search for efficiency in all things modern “convenience”, the simpler the better, but also willing to take money for convenience. In particular, high-level consumers want companies to the global situation and mutual cooperation, the shipper “Jiang Hu” unified, if the manufacturer requires additional investment, if added to the cost of mobile phones would not mind “Well Hua Xiaoqian do great things.” In fact, each family member in consumer goods, followed by “facilitate” the principle of the user gradually in “Xin Wo” and at the same time “unruly” will probably become a major obstacle to the development of mobile phones. BATCL50L  LCBTP03003 

It seems that manufacturers take into account not only the battery technology, “green”, but also the design, eliminating the “unruly” behavior.

 

Cell to become focused on short-Re board design techniques

 

As we live in the regulation of basic food and clothing “after, but also to a richer spiritual life” well-off people are also subject to the requirements of a consumer from a functional to a Multi-functional, feeling, aesthetic feelings and other psychological process will move towards the future of mobile telephony and the emergence of multi-media technology to small businesses.

 

Currently the camera functions available, send and receive multimedia messages, download games and features high-capacity telephone mobile, one of the major markets, people are increasingly willing to “pocket”. However, in the enjoyment of beautiful polyphonic ringtones, clear image, the user has indicated a marked increase in the frequency of loading is most felt that the lack of battery capacity. A user machine in color, said: “Buy the color is to follow the trend, if often hectic around the mobile phone recharge, life goes backwards.” hp Pavilion dv2000 battery  hp Pavilion dv6000 battery

 

In the multi-functional, “came to an end, all vendors are beginning to realize the core competitiveness of appearance in the mobile phone of the state of the climb. Which mobile phone manufacturers to Today ‘hui did not want their models more beautiful? “Light,” “delicious,” “Smart,” “thin” and so on ad words is none other than “small” in the past intended the word , and was even further “content” of the Nokia has also begun to focus on “the look”, you find not only young girls and hands, even the men around the mobile phone is also become increasingly small. With public enterprises on the size of the outside lines of the form, color, weight and other parameters of the process to reflect on several occasions, the mobile phones of tomorrow will be small, light of the extreme beauty. However, merchants have thought: “Hutouhunao” apparently Ben mobile phone battery will also “small” a stumbling block?

 

On the capacity of cellular telephone and shape the future of cell phone restrictions, this survey, 23% of users have put forward (see Figure II). Undoubtedly, mobile phone battery mobile phone has become a “content” and “look” to perfect a short board.

 

How do I reach this piece of board? We recommend: Heavy research and development, re-design. Developed a more environmentally friendly materials, energy and more energy effective action, people worry more time saver, and mobile phones will be the trend of green consumption, design of small general purpose batteries and chargers, including the high-end color machines, including mobile phones more quickly in the daily lives of people, which allows users to “Love Machine graduate.”
