摘要
Bulk-type all-solid-state batteries currently use a compressed powder pellet with the thickness of several hundred micrometers as a solid electrolyte separator. In this study, all-solid-state lithium secondary batteries (In/LiCoO2) with a thin Li2S-P2S5 solid electrolyte separator were constructed; their charge-discharge performance was investigated. The all-solid-state batteries using the Li2S-P2S5 separator with a thickness of 3 mu m were charged and discharged with the capacity of 93 nnAh g(-1). This result suggests that bulk-type all-solid-state batteries were successfully prepared with the solid electrolyte separator with several micrometer thicknesses.
