Abstract

All-solid-state Li-SeS₂ batteries (ASSLSs) are more attractive than traditional liquid Li-ion batteries due to superior thermal stability and higher energy density. However, various factors limit the practical application of all-solid-state Li-SeS₂ batteries, such as the low ionic conductivity of the solid-state electrolyte and the poor kinetic property of the cathode composite, resulting in unsatisfactory rate capability. Here, we employed a traditional ball milling method to design a Li₇P_2.9W_0.05S_10.85 glass–ceramic electrolyte with high conductivity of 2.0 mS cm^− 1 at room temperature. In order to improve the kinetic property, an interpenetrating network strategy is proposed for rational cathode composite design. Significantly, the disordered cathode composite with an interpenetrating network could promote electronic and ionic conduction and intimate contacts between the electrolyte–electrode particles. Moreover, the tortuosity factor of the carrier transport channel is considerably reduced in electrode architectures, leading to superior kinetic performance. Thus, assembled ASSLS exhibited higher capacity and better rate capability than its counterpart. This work demonstrates that an interpenetrating network is essential for improving carrier transport in cathode composite for high rate all-solid-state Li-SeS₂ batteries.
