The lithium battery is too heavy.
The effects of overweight lithium batteries include excessive positive electrode surface density, excessive positive electrode active materials, insufficient negative electrode supports, lithium ions precipitating on the surface of the negative electrode after deintercalation and lithium. precipitation, which causes battery capacity. If it is low, the cyclability of the battery becomes poor. If the surface density of the negative electrode is too high, the piece of electrode may be crushed to death when rolled, which will harm the penetration of lithium ions and affect the development of capacity. There are no major security issues.
