    　View Summary

    リチウムイオン電池用新規リチウムインサーション材料としてコバルト・ニッケル・マンガン系3元系材料の研究を行った。コバルト・ニッケル・マンガン複合水酸化物を原料として用いることで、結晶性の高い単相試料の合成に初めて成功している。また、得られた試料について、X線結晶構造解析、X線吸収分光法、電子顕微鏡、第一原理計算を行うことで、詳細な結晶構造解析と充放電反応機構の解明に成功している。通常の層状材料では遷移金属イオンは3価の状態で存在することが一般的であるが、結晶構造と電子状態の解析の結果、ニッケルが2価、マンガンが4価として存在していることを明らかにしている。また、これらの結果は第一原理計算にも支持されている。さらに、得られた材料について詳細な電気化学的キャラクタリゼーションを行っており、コバルト系層状材料よりも大きな可逆容量を発現することを明らかにしており、現在ではこれらの材料は実電池にも利用されている。
