To improve ion mobility in solid inorganic electrolyte for lithium ion battery, the hybrid electrolytes were developed in the form of the organic-inorganic meso-scale hybridization by the infiltration of liquid electrolyte into meso-porous inorganic glass membrane. Glass electrolyte membranes with nanopores were prepared by spinodal decomposition and subsequent acid leaching. The most suitable glass electrolyte membranes could be fabricated from the 7.5Na2O-46.25B2O3 -46.25SiO2 (mol%). The effect of leaching temperature, leaching time and leaching acids on the preparation of the membranes were investigated. The microstructure of the cross-section of 7.5Na2O-46.25B2O3-46.25SiO2 glass electrolytes were examined with a scanning electron microscope. Then, liquid electrolyte was infiltrated by dipping method into etched glasses electrolyte. Full cells were fabricated by LiCoO2 for cathode materials and MCMB for anode materials. Conductivity and charge-discharge test of the porous glass electrolyte membrane was measured.
