ANODE FOR ALL-SOLID SECONDARY BATTERY, ALL-SOLID SECONDARY BATTERY INCLUDING THE SAME, AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17982644 titled 'ANODE FOR ALL-SOLID SECONDARY BATTERY, ALL-SOLID SECONDARY BATTERY INCLUDING THE SAME, AND MANUFACTURING METHOD THEREOF

Simplified Explanation

The abstract describes an anode-solid electrolyte sub-assembly for an all-solid secondary battery. The sub-assembly includes an anode current collector, an anode material layer, and a solid electrolyte. The anode material layer has an interlayer and a first anode active material layer. The interlayer is made of a composite with a first metal material, and it contacts the solid electrolyte. The first anode active material layer contains lithium metal, lithium alloy, or a combination of both, with a larger particle size than the first metal material.
