SECONDARY BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18204546 titled 'SECONDARY BATTERY

Simplified Explanation

The patent application describes a secondary battery with a unique structure involving a solid electrolyte layer, a negative electrode current collector, and metallic lithium as the negative electrode active material.

  • The secondary battery includes a positive electrode, a solid electrolyte layer, a negative electrode current collector, and metallic lithium as a negative electrode active material.
  • A Mg mixture layer is present between the solid electrolyte layer and the negative electrode current collector.
  • The solid electrolyte layer contains a first solid electrolyte, while the Mg mixture layer contains a Mg and a second solid electrolyte.
  • The Young's modulus of the second solid electrolyte is lower than the Young's modulus of the first solid electrolyte.
