Lithium battery is a kind of energy storage conversion device that is used more and more widely, because its excellent electrochemical performance realizes a small-medium-large-sized market application scenario, when we talk about lithium battery When used correctly, it usually refers to small applications, that is, consumer electronics, such as smart phones and laptops. Because large and medium-sized applications are based on small application technologies, small applications have common features, 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 applications are usually Above the base station, we generally call it an energy storage battery. Therefore, when we talk about "the use of lithium batteries", it is in line with people's habits to limit lithium batteries to small applications.
The working principle of lithium batteries is nothing more than charging to reserve energy, and the discharge is converted into other energy and released. It is idle when it is neither charged nor discharged. Therefore, the correct use of lithium batteries has three aspects: correct charging, correct discharge, and proper maintenance.
Lithium battery correct charging method
Grasp the time and prevent overcharge. Doing the right thing at the right time, although the lithium battery itself has excellent electrochemical performance, however, any kind of thing will have safety hazards after deviating from the equilibrium state.
1. Charge if you want to charge. In the early days of smartphones, each mobile phone manufacturer often emphasized the use of original chargers (including charging cables) to charge consumers with power out of their original interests. Some manufacturers design special data lines and do not support other devices. Charger (including charging cable). Later, with the increasing use of smartphones and laptops, it is obviously self-restraint, so now everyone has unified the standard, a charger/line can charge different brands and nature of electrical appliances. It is convenient to charge, and one problem that users should pay attention to is to keep the battery with normal power as much as possible. Under normal circumstances, when the power is too low, both the mobile phone and the laptop will have a reminder. At this time, you need to replenish the power in time. Although the power is too low, it will not lead to a direct safety accident, but overuse will cause damage to the battery structure over time. .
2, the battery is full just fine. Lithium battery cells are also composed of many components. The new battery is good. If it takes a long time, it may be that the function of any component will decline, so there will be a risk of overcharge safety. The typical accidents that Samsung and Apple were exposed to were several times because the electric appliance owner put the mobile phone on the bed while sleeping, and finally caused burning and explosion.
3. Don't use it when charging. I have had experience, using a mobile phone while charging, especially when playing games, it is very easy to feel the heat of the mobile phone, the reason is also very simple, the mobile phone is equal to two jobs at the same time, which makes it has to pay a double labor, the body will naturally heat It is.
