Title: Tetsuya Motoi: Innovator in Aluminum-Alloy Foils
Introduction
Tetsuya Motoi is a prominent inventor based in Aichi, Japan. He has made significant contributions to the field of materials science, particularly in the development of aluminum-alloy foils. With a total of 3 patents to his name, Motoi's work is recognized for its innovative approach to enhancing the properties of aluminum alloys.
Latest Patents
One of Motoi's latest patents is for an aluminum-alloy foil that achieves both high elongation and high strength while reducing foil thickness. The chemical composition of this foil includes, in mass %, Fe: 1.0% or more and 2.0% or less, Cu: 0.1% or more and 0.5% or less, and Mn: 0.05% or less, with the remainder being aluminum and unavoidable impurities. This aluminum-alloy foil has a thickness of 20 µm or less and satisfies the relation El ≥ 100 × t/UTS, where t represents foil thickness (µm), UTS represents tensile strength (MPa), and El represents elongation (%).
Another notable patent involves a current-collector metal foil that features at least one roughened surface with numerous recessed parts. Each recessed part has an edge that surrounds a bottom-surface part, raised above the bottom-surface part. The average Feret diameter of the recessed parts ranges from 0.5 to 50 µm. This current-collector metal foil is particularly suitable for use as an electrode current collector in lithium-ion secondary batteries, sodium secondary batteries, electric double-layer capacitors, or lithium-ion capacitors.
