The Working Principle and Proper Maintenance of Lithium Battery

Lithium battery is an increasingly widely used energy storage conversion device, because its excellent electrochemical performance realizes a small-medium-large-scale market application scenario that keeps pace with the times, when we talk about lithium battery When used correctly, it usually refers to small applications, i.e. consumer electronics, such as smartphones, laptops. Because large and medium-sized applications are based on small-scale application technology, small-scale applications have common characteristics, while large and medium-sized applications are much more complex. Usually, medium-sized applications are on new energy vehicles, which we generally call power batteries; large-scale applications are usually on base stations, which are generally called energy storage batteries. Therefore, when we talk about "how to use lithium batteries", it is in line with people's habit to limit lithium batteries to small applications.

1. Understand the working principle of lithium batteries

The working principle of lithium batteries is nothing more than charging to store energy, and discharging into other energy and releasing it. It is in an idle state when it is neither charged nor discharged. Therefore, there are three major aspects of the correct use of lithium batteries: correct charging, correct discharging, and correct maintenance.

2. Correct maintenance of lithium batteries

The temperature is suitable, anti-cold and hot. When idle, lithium batteries usually do not have safety accidents. The purpose of daily maintenance is to place lithium batteries in a suitable environment, thereby delaying the aging of batteries. In fact, one of the parameters of the lithium battery is the appropriate temperature. Relatively speaking, it is not a big problem if the temperature is lower, but if it is placed at a higher temperature, as the saying goes, the extreme will reverse, and it will also cause safety problems. The idle state we are talking about is only in terms of normal environment. If the lithium battery is placed in water or close to a fire source, it is already out of the topic of "maintenance". Then, what should be done in a normal environment? The water side protects against moisture and the hot side protects against sun exposure. Therefore, the suitable environment for daily maintenance of lithium batteries should be: ventilation and coolness. These should be followed regardless of whether the lithium battery is idle independently or in an electrical appliance.

In the correct use of lithium batteries, the charging method of lithium batteries is the most important, because incorrect charging methods will cause safety problems, and discharge and daily maintenance only affect the service life of lithium batteries, and lithium batteries themselves are also a kind of consumables, no matter what we do, we can't avoid its final wear and tear, it's just that we use the right method to delay its aging.
