Abstract: A modified ceramic composite separator includes an organic support layer and a ceramic layer coated on the surface of the support layer in a thickness of 0.1 μm to 20 μm, and further comprises a dopamine or other polymer grown in-situ on the surface and interior of the support layer and the ceramic layer. The inorganic power in the ceramic layer has a particle size of 5 nm to 10 μm, and the material of the organic support layer has a molecular weight of 1000 to 100000000.
