Our laboratory studies the analysis, design, and synthesis of solid-state functional materials for energy, environmental, and biomedical applications. We are developing materials for fuel cells and lithium-ion secondary batteries, focusing on electrochemical energy with a high energy conversion efficiency. Based on the theory of crystal chemistry, we conducted a precise analysis and design of the structures. In addition, we are studying the development of bone repair materials using ceramic synthesis processes based on biomineralization, and the development of microcapsules for use in drug delivery systems.
Strategy 1
Development of lithium-ion battery materials
Strategy 2
Development of solid-state electrolytes for All-Solid-State Batteries
Strategy 3
Development of the electrolyte materials for Solid Oxide Fuel Cells
Strategy 4
Design and analysis of new ceramic materials
Prologue
The potential of apatite is to connect everything, from inorganic materials to cells. Establishing an "Apatite Science" that contributes to the realization of a "Medical-less Society."
