The invention provides a tubular covalent organic framework polyimide with good rate capability and cyclic stability performance and a preparation method thereof and a battery application. The methodadopts a hydrothermal polymerization way to synthesize the covalent organic framework polyimide having a tubular structure for the first time by using 1,4,5,8-naphthalenetetracarboxylic dianhydride and dianhydride as raw materials. The tubular covalent organic framework polyimide can be used as an energy storage material for a lithium ion battery cathode material, and has good rate capability andexcellent cyclic stability, the specific capacitance retention rate is 70% after cycling for 5000 cycles at the current density of 1.5 A/g, and the specific capacitance retention rate is still 61% andis far higher that the rate of non-tubular polyimide after the circulation of 15000 cycles. The method specifically comprises the steps of firstly adding the dianhydride and 1,3,5-tris(4-aminophenyl)benzene into distilled water, and mixing and stirring them uniformly; secondly making the mixed solution subjected to polymerization reaction at a certain temperature; finally, washing and drying a product.
