NOVELTY - The method involves adding 1.25 g sodium nitrate and 100-150 ml sulphuric acid to perform stirring process to obtain black colloid substance, where temperature and time duration of the stirring process are about 70 to 90 degree Celsius and 1-2 hrs, respectively. The black colloid substance is added with hydrochloric acid to obtain brown-yellow solution. Graphene oxide is put into a microwave oven for heating to obtain black flocculent graphite. Black slurry is coated on copper metal that is put into vacuum drying oven for drying to obtain lithium battery electrode material. USE - Microwave lithium battery electrode sulfur graphene material preparation method. ADVANTAGE - The method enables performing electrochemical testing for graphene sulfur composite electrode material to improve circulation stability and preparation capacity. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing a microwave lithium battery electrode sulfur graphene material preparation method. '(Drawing includes non-English language text)'
