A technology for preparing a high-temperature-resistant epoxy energy storage film based on a liquid crystalline ordered structure includes: S, mixing a biphenyl type liquid crystalline epoxy (LCE) monomer, a bisphenol-A epoxy monomer, and a curing agent at a certain ratio, while performing magnetic stirring treatment and oil-bath heating melting treatment, to obtain a molten mixture; and S, performing degassing treatment on the molten mixture obtained in the S, and then pouring the degassed mixture into a mold; and performing heating curing treatment on the degassed mixture through a hot-press approach to obtain an epoxy film. Incorporation of highly polarized C—F bonds into the liquid crystalline molecule-modified epoxy film increases an energy storage density of the epoxy film, and enhances high-temperature energy storage characteristics of the epoxy film; moreover, the cured epoxy film has a liquid crystalline ordered structure and achieves a synchronous enhancement of a thermal conductivity.
