Explain the precautions for the use of polymer batteries in detail

Polymer lithium ion battery test standard environment, polymer battery test precautions Ambient temperature: 20±5℃ Relative humidity: 45~85% The battery must be exhausted before the test Cell operation precautions 1. The upper edge is sealed; the upper edge is easy Damaged; do not bend the top edge. 2. The mechanical strength of the tab is not very strong, especially the aluminum plate. Do not bend the tabs. 3. Do not drop, hit or bend the battery; do not hit or step on the battery with a hammer; do not knock or discard the battery. 4. Aluminum foil packaging materials; aluminum foil packaging materials are easily pierced by sharp parts such as nickel sheets and needles; do not hit the battery with sharp parts; clean the working environment to prevent sharp parts; do not pierce the battery with nails or other sharp tools; please Do not transport or store the battery with metal objects such as necklaces and hairpins. 5. It is forbidden to short-circuit the battery at any time, otherwise it will cause serious damage to the battery. The battery is transported at 10%~50% charged state. The charging current and voltage must not exceed the following standards. Exceeding the specified value may damage the charge and discharge performance, mechanical performance and safety of the battery, resulting in heat generation and leakage. The battery charger must be able to charge at constant current and constant voltage; the charging current of a single battery must be less than 1C5A; the charging temperature range is 0~+45℃; the voltage during charging must not exceed 4.23v. The discharge current must not exceed the following standards. Discharge should be carried out within the scope of this standard. The discharge current of a single battery must be less than 2C5A; the discharge temperature range is -20~+60℃. The final discharge voltage of a single battery is not less than 2.75v. It should be noted that when the battery is not used for a long time, it may be in an over-discharged state due to its self-discharge characteristics. In order to prevent the occurrence of over-discharge, the battery should be charged regularly to keep its voltage above 3.0v. Over-discharge will cause the loss of battery performance and battery function. Don't over discharge, make a single battery less than 2.5v. In theory, polymer batteries have no operational electrolyte, but once the electrolyte leaks and contacts the skin, eyes or other parts of the body, immediately rinse the electrolyte with clean water and seek medical assistance. Do not use damaged batteries (damaged plastic edges, damaged casing, smell of electrolyte gas, electrolyte leakage, etc.). The battery that leaks electrolyte or dissipates the smell of power solution should be kept away from the fire source to prevent fire or explosion. In order to prevent battery leakage, heat generation and explosion, please pay attention to the following precautions: Do not remove the battery under any circumstances. Do not immerse the battery in water or sea water. Do not use or place batteries near heat sources, such as fires or heaters. Do not heat or throw the battery into the fire. It is forbidden to weld the battery directly. Do not charge near a fire or in a hot environment. Do not put the battery in a microwave oven or high-pressure container. Do not use or place the battery under high temperature (such as in strong sunlight or in a very hot car), because this may cause overheating, fire, or loss of function and life.
