Lug for lithium ion battery

摘要

A lithium ion battery comprises a shell, a cell disposed in the shell, and two lugs connected to the cell. Each of the lugs comprises a conductive foil with a surface and a PTC layer disposed on the surface of the conductive foil. The lugs conduct currents between the lithium ion battery and an outer circuit.

1. A lithium ion battery, comprising:
a shell; a cell, comprising a positive electrode current collector and a negative electrode current collector, disposed in the shell; and at least one lug connected to the cell, comprising:
a conductive foil having a first surface and an opposite second surface, and at least one side surface connecting the first surface to the second surface; anda PTC layer, disposed on one of the first surface and second surface of the conductive foil,wherein both of the first surface and second surface have a larger area than the at least one side surface of the conductive foil; and the conductive foil of the at least one lug is in direct contact with and electrically connected to the negative electrode current collector or the positive electrode current collector.
