▎ 摘 要
NOVELTY - A porous graphene/transitional metal sulfur compound film preparing method involves mixing the transition metal chalcogenide dispersion with graphene dispersion uniformly and vacuum filtering to obtain the film with water content of 10-20%. The resulting film is frozen, dried, placed at 300-800 degrees C and calcined to obtain the finished product. USE - Method for preparing porous graphene/transitional metal sulfur compound film. ADVANTAGE - The method enables preparing the porous graphene/transitional metal sulfur compound film with stable pore structure and active material, and better effect of exhibiting better electrochemical stability, improving the rate performance and increasing the scanning speed of 10-200 mV s-1.
