  "textContent": "The present disclosure provides a method for preparing a porous micron-sized silicon ball negative electrode material, including the following steps: performing high-temperature expansion and mechanical ball milling on a layered silicate raw material, and purifying same by hydrochloric acid washing to obtain a layered silicon dioxide; mixing the layered silicon dioxide with aluminum powder, sodium chloride and aluminum chloride, putting the mixture into a reaction container, and heating the mixture to perform a reduction reaction; and washing the reaction product by using a hydrochloric acid and hydrofluoric acid solution, then performing suction filtration to be neutral, and vacuum-drying same to obtain the porous micron-sized silicon ball.",
