What happens if there is too much electrolyte for lithium batteries?

1. There is less electrolyte, but the lack of lithium ion transmission path leads to an increase in internal resistance, excessive internal water content of the battery, battery leakage, internal short circuit of the battery, and severe polarization that causes other reactions of the lithium plate to increase the lithium plate. While drum 2, the internal resistance is too high, the positive electrode capacity cannot be played out, the negative electrode is lithium-depleted, the cycle performance is poor, and it is easy to swell at the end of the cycle. 3. For sealed batteries, lithium ion electrolyte is more prone to leakage. The first time the efficiency has little effect. But it will reduce the life span. If the amount of liquid injection is small, the resistance of the electrolyte will increase relatively, which will affect the efficiency of the first time and also reduce the life span. The water content in the electrolyte has a major impact on the transmission of lithium ions and the activity of electrode active materials, reducing capacity and life. 4. When charging more, the electrolyte will overflow from the vent and contaminate the battery shell, causing self-discharge, corroding the battery seat and other parts. The vent should be unblocked, otherwise the hydrogen released during charging will burst the battery. 5. First of all, it is seen that the negative electrode sheet should be golden yellow, and then the golden yellow color gradually fades away, slowly turning into white, and white crystals appear. The whiteness is due to the increase in the number of lithium ions in the negative electrode sheet, so it will be oxidized. A whitish phenomenon appears.
