Analysis of methods of extending lithium ion battery life

Do you understand the lithium-ion battery life prolonged method? With the rapid development of society, our lithium-ion batteries are also developing rapidly. So you understand the detailed information on the life of lithium-ion battery? Next, Xiaobian leads everyone Learn more about knowledge in detail. According to people inside the battery industry, some batteries claimed to supply 8 years may not meet this standard.

Due to the individual differences in the production and manufacturing of the electric vehicle lithium ion battery group, the degree of aging in use is also different. If appropriate measures are not taken during charging, these differences will accumulate and expand, resulting in a sharp drop in battery overall performance or severe battery life. Therefore, different charging methods is an important factor affecting the performance and life of single lithium ion battery.

Appropriate charging methods not only maximize battery capacity, but also extend battery life. Lithium-ion battery is achieved by migration between ions between the positive and negative electrodes. In theory, under this mechanism, the lithium-ion battery can always work.

However, over time, due to the increase of temperature and discharge cycles, the battery performance has decreased. Manufacturers take comparative conservative estimates, think that most commercial lithium-ion batteries cycle life between 300 and 500 cycles. Prevent exposure to high temperature and low temperature, especially during charging.

If your phone is hot on the charger, please remove it. Again, prevent charging under extremely cold conditions. Extreme temperature "may accelerate the degradation of almost all battery components".

As a guide, if the temperature exceeds 10-35 ¡ã C, please do not charge. Fast charging has always been a hot topic discussion, large DC is over-fast charging, just like pouring water into the barrel, from the long run, the bottom of the bucket will be thin, if the first soft, the battery can withstand , The influence of current, temperature, etc., life will inevitably extend.

Quick charging solution To maintain the health and service life of the battery, meet the efficiency of use, pay attention to safety. Lithium-ion batteries are more likely to have high temperatures, overcharges such as high-speed charging. Although the battery should release 100% capacity in the first year of the battery, it is usually below a given capacity, while the battery is idle is not used.

Moreover, manufacturers often pass their battery capacity too high because they understand that only extreme consumers will come to complaints. In addition, most mobile phones or tablets use a single battery without multiple battery packs, which also supplies a wider acceptable range for battery performance, and some batteries that have poor performance have also been ignored. Battery hates too full or too small.

Ideally, you will never let them charge more than 80% or discharge to less than 20%, because at either side beyond the range, it will bring pressure to the lithium-ion battery and degrade it. If you want a charged battery, please continue to fully charge, once you reach 100% power, remove it from the charger. In addition to selecting the best voltage threshold under a given condition, in order to obtain a longer service life, the lithium ion battery should not be operated at a higher voltage limit.

Just like a strenuous exercise, it is necessary to relax the muscles. After the battery is fully charged, it is also necessary to remove the battery to restore the voltage to the natural level. Although the running charger will automatically stop charging after the battery is filled, some charger will continue charging when the termination voltage drops to a given value.
