SECONDARY BATTERY AND ELECTRONIC APPARATUS

Title:

SECONDARY BATTERY AND ELECTRONIC APPARATUS

Document Type and Number:

WIPO Patent Application WO/2023/126750

Kind Code:

A1

Abstract:

There is a problem such that relative displacement of a positive plate or a negative plate occurs as a result of bending during charging or bending during discharging. As a result, irregularities occur in distribution, thus causing fluctuations in potential. In the present invention, a lithium metal film is used, without using graphite in the negative plate. A layered body is configured so that a single-side film is formed on each of two negative plate current-collectors by forming a lithium metal film by the vapor deposition or sputtering method, and the surfaces of the negative plate current-collectors on which the film was not formed are brought into contact with each other.
