1. Frequent deep charging and discharging: Lithium-ion batteries have almost no memory. When using lithium-ion batteries or lithium-ion digital products, many friends like to use up the power (protection board protection) and then recharge them, and many people In my eyes, this is also a way to activate the battery. In the use of lithium-ion batteries, we call the state of recharging after running out of power as deep charge and discharge.
In fact, deep charging and discharging is a major misunderstanding when many people use lithium-ion batteries. Scientists have concluded through experiments that the number of deep charging and discharging is directly proportional to the battery life when other environmental conditions are constant. Discharging will cause the battery life to end prematurely. Lithium-ion batteries with a long service life can easily cause battery swelling, which can cause explosions.
2. Overcharge and discharge and excessive charging and discharging current: This situation often occurs when the protection board is not properly designed and charging. We often like to charge the device for a while after the device is fully charged, so that our device can The resistance time is longer, but what many people don’t understand is that long-term overcharging and overdischarging will cause serious damage and damage to the performance of lithium-ion batteries, and extreme conditions such as explosions will occur. It’s good to be full, if you keep plugging it in the charger, it will lead to tragedy sooner or later.
3. When charging and discharging, the current of the charger and the general current load of the electrical appliance should be within the specified range. Excessive current load can easily cause the internal short circuit of the battery, which will damage the lithium ion and cause the safety of the circuit. The same applies to the voltage of the rechargeable charger. So when we use the charger, we should also pay attention to see if the charger is qualified.
4. Working environment. Lithium-ion batteries are extremely sensitive to temperature. If they are used below freezing for a long time, they may have a great impact and harm on battery life. Long-term exposure to an overheated environment will greatly reduce the battery's life. In severe cases, the internal pressure will increase and cause an explosion. Even if there is no explosion, the battery will quickly be scrapped in high heat. I feel unfortunate in some cases because of the explosion of the pool. Most of the deaths were caused by the high temperature of the working environment.
