Gel batteries are more durable. Lithium ion batteries are easy to explode in the environment of high temperature and high pressure. Gel batteries use aluminum-plastic film as the shell. When organic electrolytes are used inside, even if the liquid is very hot, it will not explode. Under the influence of external forces, it will smoke at most and will not explode.
Due to the advantages of natural materials, gel batteries can be very thin, arbitrary area and arbitrary shape.
Electrolyte is used on the side of lithium battery, so a solid shell is needed as a secondary package to contain electrolyte.
