The invention discloses a separator paper, a preparation method and a battery, and relates to the technical field of batteries, so as to solve the problems of high temperature shrinkage, low tensile strength and low wettability to electrolyte of the existing separator paper. The separator paper comprises a fiber paper base and a hydrophilic layer formed on the surface of the fiber paper base, the hydrophilic layer at least contains a hydrophilic aerogel layer, and the fiber paper base is a polydopamine modified fiber paper base. The preparation method is used for preparing the separator paper, and the battery uses the separator paper. The separator paper, preparation method and battery provided by the invention are used to improve the safety of the battery. |
