Lithium battery customization is not only the customization of its specifications, size, etc., the packaging form also requires special attention. The packaging form refers to the material and state of the outer packaging of the lithium battery by the lithium battery manufacturer. The main packaging forms of the lithium battery on the market are square, cylindrical, and soft.
The square and cylindrical shapes are both encapsulated by a hard metal material, steel shell material, and the outer material of the soft package is mainly aluminum-plastic film. For the customized packaging forms of lithium batteries, different packaging forms have different advantages and disadvantages.
The prismatic lithium battery, because it uses a hard steel metal material as the outer shell, has high hardness, and the guarantee of hardness means that it can be completely assured in safety. The disadvantage is that because the square lithium battery can be customized according to one's own needs and the production process structure is simple, there are many models on the market, and there are many models, and the process is difficult to unify.
Cylindrical lithium batteries, compared to the other two forms, the cylindrical process is the most mature, the lowest cost, and a high yield rate, which is suitable for combinations that meet the needs of all aspects. The disadvantage is that the weight is large, and the energy density of the lithium battery in its outsourcing state is relatively low.
The soft-packed lithium battery, due to the flexibility of its outer shell, has high flexibility in its shape, lightweight, and relatively large capacity. The disadvantage is that the cost is higher, and the cost performance is not high for the customization of polymer lithium batteries.
