Problem with customizing lithium batteries.6F22 carbon battery

release time:2023-08-21 Hits: Popular:AG11 battery

　　1、 Inconsistent voltage, some are low

　　1. High self discharge causing low voltage

　　The self discharge of the battery cell is large, causing its voltage to decrease faster than others. Low voltage can be eliminated by storing and checking the voltage after storage.

　　2. Uneven charging causes low voltage

　　After battery testing, uneven charging of the battery cells occurs due to inconsistent contact resistance or charging current in the testing cabinet. The voltage difference is small when stored for a short period of time (12 hours), but it is significant when stored for a long time. This low voltage has no quality issue and can be solved through charging. After being charged in production, store for more than 24 hours to measure voltage.

　　2、 Excessive internal resistance

　　1. Due to differences in detection equipment

　　If the detection accuracy is insufficient or the contact with the electrical group cannot be eliminated, it will cause a large display of internal resistance. Therefore, the principle of AC bridge method should be used to test the internal resistance instrument for detection.

　　2. Long storage time

　　Long storage of lithium batteries can cause significant capacity loss, internal passivation, and increased internal resistance, which can be solved through charging and discharging activation.

　　3. Abnormal heating causing high internal resistance

　　The processing of the battery cell (spot welding, ultrasound, etc.) causes abnormal heating of the battery, resulting in thermal closure of the diaphragm and a serious increase in internal resistance.
