Title: Hiroyoshi Aoki: Advancing Battery Electrode Technology.
Introduction
Hiroyoshi Aoki is an inventor based in Ibaraki, Japan, whose work focuses on electrode materials and battery technology. His portfolio includes 4 patents, with inventions addressing lithium-ion and all-solid-state batteries.
Latest Patents
Aoki’s patent, “Negative Electrode for Electrochemical Element and a Lithium Ion Secondary Battery,” describes a negative electrode with a composition layer on a metal-foil current collector. The layer combines a silicon-containing material with hardly graphitizable carbon. The patent specifies that the silicon-containing material makes up 50 to 90 mass percent of the active material, while the carbon makes up 10 to 50 mass percent. The electrode is intended for use in a lithium-ion battery with a positive electrode, separator, and nonaqueous electrolyte.
His patent “Electrode for All-Solid-State Battery and All-Solid-State Battery” concerns electrodes designed to support strong battery performance under load. The electrode includes a molded mixture of active material, solid electrolyte, and conductive assistant. Its composite particles have a surface layer containing one type of solid electrolyte, while another solid electrolyte is positioned between the particles. The patent describes relationships between the compositions of these electrolytes. The invention is associated with Sustainable Development Goals 12, 3, 7, and 11.
