Abstract
An all-solid-state lithium secondary battery using a NiPS3 electrode and a 80Li2S·20P2S5 glass solid electrolyte was fabricated, and the charge–discharge cycle performance of the corresponding all-solid-state cell was investigated. This all-solid-state cell exhibited a stable reversible capacity of about 80 mA h g−1 after 30 cycles with a current density of 64 µA cm−2 at room temperature. This suggests that NiPS3 has a potential as an electrode active material in all-solid-state lithium secondary batteries using Li2S-P2S5 solid electrolytes.
