Lithium-ion batteries are used in Bitpott solar庭院灯 and other products. Some lower quality lithium batteries may experience cell swelling. What causes this? Research shows that:
1. The expansion caused by thickness changes during the lithium-ion insertion process. This occurs because during charging, lithium ions exit the positive electrode and embed themselves in the negative electrode, causing an increase in the interlayer spacing of the negative electrode, which leads to cell swelling. The general rule is that the thicker the cell, the greater the swelling.
2. Improper process parameters during the manufacturing of the lithium battery cell. Ineffective process control is an important reason for cell swelling. During the manufacturing process, variations in slurry dispersion, compaction density, negative-positive ratio, temperature control, electrolyte quantity, and internal pressure can all cause cell swelling. Water, in particular, needs to be strictly controlled, as the highly reactive lithium carbide formed during charging is very sensitive to water. If they come into contact, a violent chemical reaction occurs, producing gas and increasing internal pressure, which can lead to swelling. Therefore, in the production of lithium batteries, not only must the extreme plates be desiccated, but moisture control equipment should also be used during the injection process.
