What factors affect the performance of 3C lithium-ion battery

The charging and discharging current is divided into charging current and discharging current. Charging current has a greater impact on battery capacity, life and safety. The larger the charging current, the smaller the actual capacity that can be charged. It will also reduce the cycle life of 3C lithium-ion batteries; the size of the discharge current will also affect 3C lithium ion battery, the higher the discharge rate, the less the capacity that can be released. If the battery is discharged at a high rate for a long time, the life of the 3C lithium ion battery will quickly decay. Only 3C lithium-ion batteries with moderate load working current can be used well. 2. Operating temperature 3C Li-ion battery has a clear operating temperature range. Under normal conditions, the charging temperature is specified to be 0 to 45 degrees, and the discharge temperature is -20 to 60 degrees. When charging a 3C lithium ion battery at a low temperature, metallic lithium ions will precipitate on the surface of the battery anode to form dendrites. Once the diaphragm between the anode and the cathode is pierced, it will cause an internal short circuit of the battery, causing the 3C lithium ion battery to burn and explode. , Causing serious consequences; long-term operation of 3C lithium-ion batteries at high temperatures will affect the cycle life, and abnormalities may not be seen in a short period of time. Over time, the battery will bulge and leak. The 3C lithium ion battery is best used within the specified temperature range. 3. Types of materials The performance of 3C lithium-ion batteries has a lot to do with the choice of materials. Materials with poor cycle performance have a lower battery life and even safety cannot be guaranteed. The cycle performance of a 3C lithium-ion battery is related to the cycle performance of the positive electrode and the electrolyte and the cycle performance of the negative electrode and the electrolyte. The performance of 3C lithium-ion battery will be good if you choose good materials for both poles. If you choose a good material for one pole and a poor material for the other pole, the cycle performance of the 3C lithium ion battery will change from that of the poorer material. To decide. 4. Testing conditions 3C lithium-ion batteries must be tested before they can be used. The selection of testing modules, charge/discharge rate, testing temperature, contact resistance between the testing point and the cell, cut-off voltage, current and other factors will affect 3C lithium-ion batteries The result of the performance test. Uniform testing standards, knowing the characteristics of materials, and choosing appropriate modules are the prerequisites for the testing of 3C lithium-ion batteries. The 3C lithium-ion battery can be connected with the shrapnel micro-needle module, which can transmit large currents and has a stable response in the field of small pitches.
