ALL SOLID STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17975669 titled 'ALL SOLID STATE BATTERY

Simplified Explanation

The present disclosure is about an all solid state battery that aims to suppress the increase of internal resistance. The battery consists of a cathode, an anode, and a solid electrolyte layer between them. The anode includes an anode active material layer, an anode current collector, and a molten salt with a melting point between 30°C and 80°C. The anode active material layer contains an anode active material and a sulfide solid electrolyte. The anode current collector undergoes sulfidation due to the sulfide solid electrolyte.

Original Abstract Submitted

A main object of the present disclosure is to provide an all solid state battery in which increase of internal resistance is suppressed. The present disclosure achieves the object by providing an all solid state battery including a cathode, an anode, and a solid electrolyte layer arranged between the cathode and the anode, wherein: the anode includes an anode active material layer and an anode current collector; the anode active material layer contains an anode active material, a sulfide solid electrolyte, and a molten salt of which melting point is 30° C. or more and 80° C. or less; and the anode current collector is a current collector in which a sulfidation due to the sulfide solid electrolyte occurs.
