Title: Jyo Saitou: Innovator in Battery Technology

Introduction

Jyo Saitou is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of battery technology, particularly in the development of positive electrode active materials.

Latest Patents

Saitou holds two patents, with his latest focusing on a method for manufacturing positive electrode active material and a secondary battery. This innovative material exhibits a minimal difference in crystal structure between its charged and discharged states. Specifically, the positive electrode active material transitions from a layered rock-salt crystal structure in the discharged state to a pseudo-spinel crystal structure when charged at a high voltage of approximately 4.6 V. This unique characteristic allows for reduced changes in crystal structure and volume during charging and discharging cycles compared to conventional materials. To achieve this, a halogen source, such as fluorine, and a magnesium source are mixed with pre-synthesized particles of a composite oxide containing lithium, a transition metal, and oxygen, followed by heating the mixture at an appropriate temperature for a specified duration.
