Application: Negative-electrode material and battery using the same (Patent ID: US20230420667A1)
The patent filed by Panasonic Holdings Corp. describes a negative-electrode material for batteries, consisting of a negative-electrode active material and a solid electrolyte. The negative-electrode active material contains Li, Ti, M1, and O, with M1 being a metal or metalloid element other than Li and Ti. The solid electrolyte contains Li, M2, and X, with M2 being a metal or metalloid element other than Li, and X being F, Cl, Br, or I. The material is designed to improve the performance and efficiency of batteries.
The claims further detail specific compositions and parameters for the negative-electrode material, such as the presence of elements like Zr, Cs, Ce, and Ca in M1, the formulas representing the negative-electrode active material, and the ranges for the variables a and ß. Additionally, the claims specify that the solid electrolyte should be free of sulfur. The patent also extends to a battery comprising a positive-electrode layer, a negative-electrode layer containing the described material, and an electrolyte layer between them. Overall, the patent aims to enhance the functionality and reliability of batteries through the use of this specific negative-electrode material.
