This invention belongs to the technical field of sodium-ion battery electrode materials, specifically relating to a preparation method and application of an air-stable molten asphalt-coated sodium selenide composite cathode sodium replenisher. The invention first prepares pure-phase sodium selenide nanoparticles in a glove box by room temperature stirring. Then, asphalt is grown in situ on the surface of the sodium selenide through ball milling and high-temperature calcination, thereby forming a core-shell structured sodium selenide composite sodium replenisher material coated with molten asphalt. The resulting composite sodium replenisher is stable in air for extended periods without deterioration, while simultaneously reducing the decomposition potential of sodium selenide and improving its decomposition efficiency. Coupled with a layered oxide cathode, it can achieve cathode sodium replenishment, compensating for the loss of active sodium caused by the growth of the SEI film on the surface of the hard carbon anode. Furthermore, its decomposition product, selenium, can inhibit the lattice oxygen evolution of the layered oxide cathode, improving the structural stability of the cathode and thus effectively enhancing the battery's initial efficiency and cycle performance, demonstrating promising commercial application prospects.
