It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-LISICON Li10SnP2S12, garnet Li7La3Zr2O12, perovskite Li3xLa(2/3)-xTiO3, NASICON Li1.3Al0.3Ti1.7(PO4)3 and glass-ceramic xLi2S£¿(1-x)P2S5 and their progress are described in great detail. Meanwhile, the review discusses different on-going strategies on enhancing conductivity, optimizing electrolyte/electrode interface and improving cell performance. %K all solid state %K lithium batteries %K inorganic electrolytes %K ion conductivity %K interface. %U http://www.frontiersin.org/Journal/10.3389/fenrg.2014.00025/abstract
