The achievement of a high capacity by a thin-film-solid-state fluoride shuttle battery

A fluoride shuttle battery with a high capacity of ~800 mAh g^-1 at 150 ℃ can be prepared using a Cu positive electrode and a LaF₃ negative electrode with a thin-film solid electrolyte battery.

Cu正極、LaF₃負極を用いて、150℃で~800 mAh g^-1の高容量を示す薄膜型固体フッ化物イオンシャトル二次電池が作製できることを明らかとしました。
