2021-2-22 The highest room temperature ionic conductivity of the liquid-phase-synthesized Na11Sn2PS12 electrolytes (LP-Na11Sn2PS12) is 1.73 × 10–4 S cm–1, which is comparable with that of ball-milling samples (BM-Na11Sn2PS12) of 2.16 × 10–4 S cm–1. Both Na11Sn2PS12 electrolytes show an electrochemical window of 0.3–3.2 V.

2018-6-15 A single-phase Li 1.5 Al 0.5 Ge 1.5 (PO 4) 3 solid electrolyte could be obtained by the liquid-phase method, which showed higher conductivity than the counterpart prepared by solid-phase method. A cold sintering process (CSP) was reported to densify Li 1.5 Al 0.4 Cr 0.1 Ge 1.5 (PO 4 ) 3 electrolytes at low temperatures, which could avoid lithium loss and second phase formation caused by high

2019-1-17 Solid electrolytes are the key to realize future solid-state batteries that show the advantages of high energy density and intrinsic safety. However, most solid electrolytes require long time and energy-consuming synthesis conditions of either extended ball milling or high-temperature solid-state reactions, impeding practical applications of solid electrolytes for large-scale systems.

2020-12-15 Wet ball milling is beneficial to the contact between Li 2 S and P 2 S 5 molecules, make them react sufficiently and produce electrolyte particles with a smaller size. In these regards, electrolytes and cathode materials can be mixed more uniformly, thereby the interfacial resistance will be reduced and the electrochemical performance of such a ...

2019-12-12 Due to the volatility of P2S5, the ambient pressure synthesis of Li2S + P2S5 (LPS) has been limited to planetary ball-milling (PBM). To utilize PBM of LPS to generate a solid electrolyte (SE), the as-synthesized powder sample must be pressed into pellets, and as such the presence of as-pressed grain boundaries in the SE cannot be avoided. To eliminate the grain boundaries, LPS doped with
