Title: Takafumi Tsukagoshi: Innovator in Battery Technology
Introduction
Takafumi Tsukagoshi is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of battery technology, holding a total of 8 patents. His innovative work focuses on improving the efficiency and safety of nonaqueous electrolyte secondary batteries.
Latest Patents
One of his latest patents is a separator designed for nonaqueous electrolyte secondary batteries. This separator features a resin substrate, a first heat-resistant layer that covers one surface of the substrate, and a second heat-resistant layer that partially covers the opposite surface. The design includes an uncovered region that connects to the end portion of the resin substrate. Each heat-resistant layer contains inorganic particles and a binder, with the inorganic particles making up 50-90 mass % and the binder 10-50 mass %.
Another notable patent is for a nonaqueous electrolyte secondary battery that consists of an electrode body formed by alternately laminating multiple positive and negative electrodes, with separators interposed between them. Each separator is made of a porous resin substrate and a porous heat-resistant layer, which has a larger surface roughness than the resin substrate. The electrode body includes bonding particles that connect the negative electrode to the heat-resistant layer and the positive electrode to the resin substrate. The mass of bonding particles at the interface between the negative electrode and the heat-resistant layer is greater than that at the interface between the positive electrode and the resin substrate.
