3C lithium battery function is good or bad to determine the use of the battery, in order not to affect the use of 3C lithium battery, in the production process, it must be tested, with the ability to transmit high current shrapnel micro-needle module connection, check the battery function is qualified. 3C lithium battery function is usually affected by certain elements, forming a decline in capacity, functional decay, loss of battery life. And charge and discharge current, operating temperature, material varieties, test conditions and other factors may affect the function of 3C lithium batteries.
1. Charge and discharge current
Charging and discharging current is divided into charging current and discharging current. Charging current has a greater impact on battery capacity, longevity and safety, the larger the charging current, the smaller the capacity can be charged in practice, but also reduce the cycle life of 3C lithium battery; the size of the discharge current will also affect the 3C lithium battery, the larger the discharge rate, the less capacity can be released, if the long-term discharge of the battery at a large rate, the life of 3C lithium battery will decay rapidly. As long as the load working current moderate 3C lithium battery can be used better.
2. Working temperature
3C lithium battery has a clear range of operating temperature, the regular state of the rule charging temperature is 0 to 45 degrees, the discharge temperature of -20 to 60 degrees. 3C lithium battery charging in a low-temperature state, the surface of the anode of the battery will have lithium metal separation, the formation of dendrites, once pierced the anode and cathode diaphragm, will trigger a short circuit inside the cell, causing 3C lithium battery incineration, explosion, the formation of serious results; 3C lithium battery long-term work in a high-temperature state will affect the cycle life, the short-term may not see anomalies, a long time, the battery will present bulging, leakage, etc.. 3C lithium batteries are best used within the temperature range of the rules.
3. Material variety
The function of 3C lithium battery has a lot to do with the selection of the material, the cycle function is poor, the battery life is lower, even the safety is not guaranteed. 3C lithium battery cycle function is related to the cycle function of the positive electrode and electrolyte matching and the cycle function of the negative electrode and electrolyte matching. The function of 3C lithium battery will be good if both poles are selected with good materials, and if one pole is selected with good materials and the other pole is selected with poor materials, the cycle function of 3C lithium battery will be resolved by the pole with poorer materials.
4. Test conditions
3C lithium battery needs to be tested before it can be used, the selection of the test module, charge/discharge rate, temperature of the test, the test point and the core touch internal resistance, cut-off voltage, current and other factors will affect the results of the 3C lithium battery function test.
Consistent test specifications, understanding the characteristics of the material, selection of suitable modules, etc. is the premise of the 3C lithium battery test. High-current shrapnel micro-pin module can be connected to 3C lithium battery, which can transmit high current, and has a stable response in the field of small pitch.
3C lithium battery test, in the range of 1-50A, high-current shrapnel micro-pin module current transmission are very stable, and will not produce current attenuation, has a good connection function. In the small ≤ 0.2mm pitch, the high-current shrapnel micropin module can also cope with it, and can maintain a long-term stable connection, without pin jamming or breaking the pin. With the shrapnel micro-pin module, not only can guarantee the 3C lithium battery test stable, but also can improve the test power, so that the 3C lithium battery function test has a good result.
