superionic conductor, tetragonal Na3SbS4, is described. Importantly, Na3SbS4 can be prepared by scalable solution processes using methanol or water, and it exhibits high conductivities of 0.1–0.3 mS cm−1. The solution‐processed, highly conductive solidified Na3SbS4 electrolyte coated on an active material (NaCrO2) demonstrates dramatically improved electrochemical performance in all‐solid‐state batteries.
在室温下运行的全固态钠离子电池是用于大型能量存储系统的有吸引力的候选对象。但是,固体电解质的材料创新必须满足多种要求,包括高电导率,实现与活性材料紧密离子接触的功能性合成方案以及空气稳定性。描述了一种新的高导电性(25°C时为1.1 mS cm -1,E a = 0.20 eV)和干燥空气稳定的钠超离子导体四方Na 3 SbS 4。重要的是,Na 3 SbS 4可以使用甲醇或水通过可扩展的溶液方法制备,并且具有0.1-0.3 mS cm的高电导率-1。固溶在活性材料(NaCrO 2)上的固溶处理的高导电性Na 3 SbS 4电解质在全固态电池中表现出显着改善的电化学性能。
