Title: Innovations of Katsushi Abe in Hydrogen Storage Technology

Introduction

Katsushi Abe is a notable inventor based in Aichi-ken, Japan. He has made significant contributions to the field of hydrogen storage technology, holding 2 patents that focus on enhancing the performance and efficiency of hydrogen absorbing alloys.

Latest Patents

One of his latest patents is a surface treatment method for hydrogen absorbing alloys. This method involves contacting steam with a hydrogen absorbing alloy within a temperature range of 200°C to 400°C. Through a catalytic reaction with water, the metal in the alloy is transformed into an oxide or hydroxide. The hydrogen produced facilitates the reduction of nickel compounds, resulting in the production of catalytically active nickel metal. This activation treatment is particularly beneficial for hydrogen absorbing alloys used as active materials in the negative electrodes of secondary batteries.

Another significant patent is related to a sealed nickel/metal hydride battery. This invention provides an electrode design and manufacturing method that minimizes the decrease in charging reserve of the hydrogen-storage alloy electrode while also controlling the internal pressure of the battery. The electrode is constructed using a tackifier or binder made from an organic polymer material containing ether linkages, such as polyethylene oxide, polypropylene oxide, or polybutylene oxide. This material is hydrophilic and exhibits superior oxidation resistance compared to conventional materials, significantly reducing hydrogen production due to oxidation and decomposition.
