The structure and composition of lithium batteries and precautions for storage and maintenance

Structure of Lithium Battery Lithium battery is an alternative product of metal lithium battery that appeared in the past few years. The main components of the battery are positive and negative electrodes, electrolyte, separator and casing. Positive electrode-A carbon electrode that can absorb lithium ions is used. When discharged, lithium becomes lithium ions, which leave the anode of the battery and reach the cathode of the lithium battery. For the negative electrode-material, select the lithium compound that can be inserted as close as possible to the lithium potential. For example, various carbon materials include natural graphite, synthetic graphite, carbon fiber, mesophase sphere carbon, etc. and metal oxides. Electrolyte-a mixed solvent system that uses LiPF6 ethylene carbonate, propylene carbonate and low-viscosity diethyl carbonate and other alkyl carbonates. Diaphragm-the use of polyolefin microporous membranes such as PE, PP or their composite membranes, especially the PP/PE/PP three-layer membrane not only has a lower melting point, but also has a higher puncture resistance, which plays a role in heat insurance. Precautions for storage and maintenance Battery use environment Lithium battery manufacturer's analysis Please use lithium battery within the ambient temperature of -10℃~45℃ to guard against water, beverages, and corrosive liquids in the battery, which may cause battery leakage, heat generation, smoke, fire or explosion Keep the battery close to heat sources, open flames, flammable and explosive gases, liquids, which may cause the battery to leak, heat, smoke, fire or explode. If metal foreign objects enter the battery box, it may cause the battery to leak, heat, and smoke. , Fire or explosion. Battery Charging Environment Lithium battery manufacturer's analysis Please charge the battery within the ambient temperature of 0℃~35℃. Do not charge more than 24 hours. Overcharging will shorten the battery life. Attention: The charging function below 0℃ is closed, please keep it at 0℃ Recharge the battery in the above environment. Warning: Using non-original chargers may cause the battery to leak, heat, smoke, fire or explode. Note Lithium battery manufacturers say that in order to extend the battery life to a large extent, keep them where possible. The battery power is recycled between 20% and 80%. Lithium battery manufacturers suggest that when riding, please operate the throttle handle slowly. Do not store the battery in an environment higher than 40℃, which will cause irreversible capacity degradation of the battery. Beware of storing the battery in a place where there is a risk of falling. It may cause uncontrollable damage inside the battery, and may cause leakage, heat generation, smoke, fire or operation of the battery.
