Current available organic liquid electrolytes of electrochemical energy devices lead to fast performance degra-dation and even combustion. Such challenges call for the development of advanced electrolytes with remarkable safety and electrochemical performances. Via integrating the merits of ionic liquids and liquid crystals, the emerging ionic liquid crystals (ILCs) enable the feasibility of design, manipulation of defined ion transport channels through modulated nanosegregated structures, and the high operational safety. Previous reviews rarely focus on the ion conductive and working mechanis...
