Abstract

All-solid-state lithium batteries using LiBH₄ electrolyte and LiCoO₂ cathode were prepared, and the effect of the intermediate layers between LiBH₄ and LiCoO₂ was demonstrated by electrochemical measurement. Li₃PO₄, LiNbO₃ and Al₂O₃ thin films with smooth surfaces deposited by PLD were utilized for the intermediate layer. With the intermediate layer, the interfacial resistance between LiBH₄ and LiCoO₂ decreased by as much as 3 orders of magnitude by suppressing the interfacial reaction between LiBH₄ and LiCoO₂. A 10-25 nm-thick Li ₃PO₄ intermediate layer was found to be the most effective to suppress the interfacial resistance.
