a The Arrhenius ionic conductivity plots of antiperovskite in the temperature range from 25 to 120 °C, the ionic conductivity data of Li2OHCl (black) are reproduced from the work of Z. D. Hood et al.26. b Schematic diagram of nonequivalent sites for Li+ ions transport in the orthorhombic lattice. c Schematic diagram of equivalent sites for Li+ ions transport in the cubic lattice, Li+ ions in blue, Cl‒ ions in green. d The activation energy of (Li2OH)1‒xKxCl increases with the increase of K-doping, and the error bars represent the standard deviation calculated by linearly fitting the Arrhenius ionic conductivity plots. e The ionic conductivity of (Li2OH)1‒xKxCl decreases with the increase of K-doping. f The Li–O bond distance of (Li2OH)1‒xKxCl decreases with the increase of K-doping according to the PDF data.
