Analysis of lithium battery protection methods

Also called primary lithium battery. The discharge can be continued or intermittently. Once the electricity is exhausted, it can no longer be used, and it is widely used in low-power electronic products such as cameras. The self-discharge of lithium primary batteries is very low and can be stored for 3 years. The effect will be better when stored under refrigerated conditions. It is a good way to store lithium primary batteries in a cold place. Note: Lithium primary batteries are different from lithium batteries. Lithium primary batteries cannot be charged and charging is very dangerous! 2. Lithium batteries are also called secondary lithium batteries. It can be stored for more than half a year at 20°C. This is due to its low self-discharge rate and most of its capacity can be recovered. The self-discharge phenomenon of lithium batteries, if the battery voltage is kept below 3.6V for a long time, it will cause the battery to over-discharge and destroy the internal structure of the battery and reduce the battery life. Therefore, long-term storage of lithium batteries should be recharged every 3 to 6 months, that is, charged to a voltage of 3.8 to 3.9V (the best storage voltage of lithium batteries is about 3.85V), and it is advisable to maintain the discharge depth at 40%-60% , Should not overflow. The battery should be stored in a dry environment at 4°C~35°C or in moisture-proof packaging. Keep away from heat sources and do not place in direct sunlight. Lithium batteries have a wide operating temperature range. They can still be used outdoors in winter in the north, but the capacity will be much lower. If they return to room temperature, the capacity can be restored.
