Abstract

The invention relates to a thin-film lithium-ion battery. The thin-film lithium-ion battery comprises a positive plate, a negative plate and a solid electrolyte film. The solid electrolyte thin film is arranged between the positive plate and the negative plate. At least one of the positive plate and the negative plate comprises a current collector. The current collector is of a layered structure consisting of a plurality of carbon nanotubes.

Description

technical field [0001] The invention relates to a thin film lithium ion battery. Background technique [0002] Existing thin-film lithium-ion batteries include an outer casing, a positive electrode sheet packaged in the outer casing, a negative electrode sheet, and a solid electrolyte disposed between the positive electrode sheet and the negative electrode sheet. The positive sheet includes a positive current collector and a positive material layer formed on the surface of the positive current collector. The negative electrode sheet includes a negative electrode current collector and a negative electrode material layer formed on the surface of the negative electrode current collector. Thin-film lithium-ion batteries are widely used in various fields due to their thinness and lightness. [0003] A current collector in a battery is a structure used to collect electric current. The function of the current collector is mainly to gather the current generated by the active mate...
