Solution: It can be solved by charging and discharging activation. Lithium batteries are stored for too long, resulting in excessive capacity loss, internal passivation, and increased internal resistance. Solution: The internal resistance should be tested by the principle of AC (Alternating Current) bridge method. If the detection accuracy is not enough or the contact resistance cannot be eliminated, it will show that the internal resistance is too large. Root cause 1: Detecting equipment differences.
Solution: This low voltage has nothing to do with quality issues and can be solved by charging. In the short-term storage (12 hours), the voltage difference is very small, but the voltage difference is large when stored for a long time. Due to contact resistance or detection of charge, the current is inconsistent caused by the uneven charge of the cell. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. Root cause 1: High self-discharge, which causes low voltage. If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected.
Hope our post help you with what you need. So in here in this post, we share with you some of the most commonly seen root causes to lithium-ion battery accident and their solutions. As widely used as lithium-ion battery, it’s not uncommon that similar incidents happen every now and then. “…lithium battery caught fire, and exploded…” No, not another one! This is what we say or hear someone else say when there’s news about yet another battery accident.
