    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.
