Abstract: A separator and a method for preparing the separator are provided. The separator includes a polymer substrate,a ceramic layer provided on the polymer substrate and an infiltration part formed between the polymer substrate and the ceramic layer. The polymer substrate contains a base polymer and a first curing resin. The infiltration part has at least a portion infiltrated into the polymer substrate. Each of the infiltration part and the ceramic layer independently contains ceramic particles and a second curing resin.A battery including the separator is also provided.

Abstract: A separator for a lithium-ion battery includes a substrate, a coating, and a middle layer formed between the substrate and the coating. The middle layer includes a part of the substrate and a part of the coating. The substrate contains a base polymer, a first polymer, and a first inorganic material. The coating contains a second polymer and a second inorganic material. The first polymer and the second polymer independently contain an acid radical in a side chain thereof. The first inorganic material is reactive with the first polymer via a first neutralization reaction, and the second inorganic material is reactive with the second polymer via a second neutralization reaction. A method for preparing a separator for a lithium-ion battery and a lithium-ion battery are also provided.
