Lithium ion secondary batteries. The lithium-ion secondary battery typically includes an electrode assembly, a container containing the electrode assembly, and an electrolyte. The electrode assembly includes two electrodes with opposite polarity and a separator. The separator includes a porous membrane containing ceramic particle clusters. The porous film is formed by bonding particle clusters with an adhesive. Each particle cluster is formed by sintering or by dissolving and recrystallizing all or part of the ceramic particles. The ceramic particle contains a ceramic material with a band gap. Each particle cluster can have the shape of grape clusters or thin layers, and can be formed by laminating ceramic particles in the shape of scales or thin layers
