Title:
SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/241429
Kind Code:
A1
Abstract:
The present invention provides a solid-state battery that has a sufficiently high usage rate of a negative electrode active material during charging and discharging, even when having a lower content of a conductive assistant. The solid-state battery includes a positive electrode layer, a negative electrode layer and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer, wherein, of the positive electrode layer and the negative electrode layer, at least one electrode layer contains a conductive assistant 201 configured from a metal material, and in the aforementioned electrode layer, the conductive assistant 201 is covered by a coating material 202 that has a higher melting point than that of the conductive assistant.
