description The invention relates to a preparation method and application of a selenium indium sulfide/carbon negative electrode material for a potassium ion battery. The preparation method comprises the following steps: synthesizing an indium-based metal organic framework as a precursor, and synchronously realizing the combination of a sulfur source and a selenium source with indium in the precursor in a high-temperature calcination process to form In2. 67Se2S2 particles uniformly anchored on a carbon skeleton, so as to present a one-dimensional nanorod structure. In < 2.67 > Se2S2 particles are coated with amorphous carbon, so that the In < 2.67 > Se2S2/C composite material has higher conductivity, an excellent electronic structure and more active sites, the transfer of electrons and ions is accelerated, meanwhile, the interlayer spacing is enlarged, aggregation in the charging and discharging process is prevented, and the reaction kinetics is further improved. Experiments show that the In2. 67Se2S2/C composite materia
