In the present study, we prepared new Li-ion batteries with inorganic membrane-coated electrodes fabricated by the direct coating of a 400-nm-sized Al 2O 3 particles onto the anodes and studied their charge-discharge characteristics for the first time. Being made of 94 wt.% Al 2O 3 powder and 6 wt.% polymeric binder, the membranes on the anodes showed excellent wettability with the liquid electrolytes, due to their high porosity and capillarity. The Li-ion batteries prepared by the assembly of the inorganic membrane-coated electrodes showed excellent charge-discharge behavior compared to conventional Liion batteries with a polymeric separator. However, their high-rate performance was affected by the binder contents in the inorganic membranes. The thermal properties of the Li-ion battery with the inorganic membrane-coated electrodes were compared with those of a conventional one with a polymeric separator.
