Anti-perovskite solid-state electrolyte Li2OHCl usually exhibits orthorhombic phase and low ionic conductivity at room temperature.However,its ionic conductivity increases greatly when the temperature is up to 40 ℃,while it goes through an orthorhombic-to-cubic phase transition.The cubic Li2OHCl with high ionic conductivity is stabilized at room temperature and even lower temperature about 10 ℃ by a simple synthesis method of wet mechanical milling.The cubic Li2OHCl prepared by this method performs an ionic conductivity of 4.27 ×10-6 S/cm at room temperature,about one order of magnitude higher than that of the orthorhombic Li2OHCl.The phase-transition temperature is decreased to around 10 ℃.Moreover,it can still remain cubic phase after heat treatment at 210 ℃.This work delivers a huge potential of fabricating high ionic conductivity phase anti-perovskite solid-state electrolyte materials by wet mechanical milling.

中国是一个海洋大国,不仅拥有漫长的海岸线,还有数量众多的岛礁.而在浙江省舟山市的最东端,就有一个基本由海岛组成的普陀区,整个区共包括大大小小450多个海岛.这些岛屿有的名气很大,如普陀山岛、桃花岛、朱家尖岛、珞珈山岛等,都是全国著名的旅游胜地,而像六横岛、虾峙岛这一类旅游活动不发达的岛屿,知道的人就不多了.除了这些大岛,还有一些如笔架山岛、大蚊虫岛、小蚂蚁岛等无人居住的小岛,就更加是无人知晓,甚至连本地人都不—定听说过.
