▎ 摘　　要

NOVELTY - The method involves mixing aqueous suspension manganese oxide nano-particle, precursor and graphene i.e. graphene oxide, to obtain mix solution, where the manganese oxide nano-particle is manganese dioxide and tri-manganese tetroxide. The mix solution is dried by using a spray dryer to obtain solid powder. Heating process is perfumed by the solid powder to obtain manganese oxide/graphene porous microsphere, where temperature value is about 80 to 350 degree Celsius. Micro-sphere is made of lithium ion battery cathode material and super capacitor electrode material. USE - Manganese oxide/graphene porous micro-sphere preparation method. ADVANTAGE - The method enables executing micro-sphere preparation process to obtain excellent storage of manganese oxide/graphene composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a manganese oxide/graphene porous microsphere. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing a manganese oxide/graphene porous micro-sphere preparation method. '(Drawing includes non-English language text)'
