Plastic case lithium ionic cell

The utility model relates to a novel plastic casing lithium ion cell, which belongs to the technical field of lithium ion cells. The plastic casing cell comprises a cell core body and a casing body, wherein a positive pole rod and a negative pole rod are arranged on the casing body. The utility model is characterized in that the casing body comprises a corrosion-resisting layer which is arranged in the inner layer, a protective layer which is arranged on the outer layer and a metal isolated layer which is arranged between the corrosion-resisting layer and the protective layer. The novel plastic casing lithium ion cell adopts a special cell structure, which increases the sealing effect of a plastic casing body, and proves a small-volume plastic casing cell which has the advantages of security, reliability, low cost and easy getting for lithium ion cell filed, and can replace the existing metal casing cells.
