High lithium ionic conductivity is exhibited by an organic–inorganic hybrid electrolyte prepared by self‐assembly of a PEO‐PPO‐PEO triblock copolymer (Pluronic F127; PEO=poly(ethylene oxide), PPO=poly(propylene oxide)), complexed with LiClO 4 , on a silica framework. The good performance of the hybrid material with an [O]:[Li] ratio of 16:1 is due to its well‐ordered mesophase consisting of a hexagonal arrangement of cylinders (see diagram).
