Abstract
A metal sulfide negative material of a sodium ion battery and a preparation method thereof. The material has porous nanoparticles with a particle size of 5 nm to 500 nm, and the metal sulfide negative material of the sodium ion battery is at least one of zinc sulfide or copper sulfide. The preparation method includes the steps of preparing a mixed solution of stannous chloride and metal salt, adding polyvinylpyrrolidone into the mixed solution to obtain a solution A, introducing reaction gas into the solution A, aging after the reaction to obtain a precipitate, and soaking the precipitate in a persulfide solution to obtain the metal sulfide sodium ion battery negative material.
