Method for preparing hollow microporous carbon sphere coated nanometer sulfur molecular material

The invention discloses a method for preparing a hollow microporous carbon sphere coated nanometer sulfur molecular material, and belongs to the field of the chemical battery. The method comprises the steps of dissolving TPOS into a solution containing ethyl alcohol, water and ammonia water; then adding resorcinol and formaldehyde; carrying out centrifuging, washing, and calcining under argon after the reaction is finished; then mixing with an HF water solution to perform a corrosion reaction to obtain hollow microporous carbon spheres; and enabling the hollow microporous carbon spheres to be reacted with sublimed sulfur in a grinding and mixing manner to obtain the hollow microporous carbon sphere coated nanometer sulfur molecular material. The hollow microporous carbon sphere coated nanometer sulfur molecular material prepared by the invention is uniform in appearance, and relatively high in specific surface area and large-pore volume, so that the material can contain relatively high sulfur content; and the
