Abstract

A MoO₂-doped Li_5.5PS_4.5Cl_1.5 solid electrolyte with ionic conductivity of 12 mS cm⁻¹ and an electrochemical window of 4.3 V vs. Li/Li⁺ was prepared, which enables a LiNi_0.8Co_0.1Mn_0.1O₂-based full cell to deliver a specific capacity of 194 mA h g⁻¹ at 0.1C and retain 80% capacity after 3500 cycles at 1C.
