▎ 摘　　要

NOVELTY - The battery has a battery body provided with an anode, a cathode and an outer circuit. The anode is connected with the cathode through an electric way, where the cathode is selected from carbide key cobalt/graphene composite material and coated with a catalyst layer. The catalyst layer is made of carbide key cobalt/graphene composite material, where mix quality percentage of the carbide key cobalt/graphene composite material is 5 wt. %. A carbon paper is covered with nafion material. USE - Micro-biological fuel battery. ADVANTAGE - The battery uniformly loads graphite alkene to directly make a reduction electrode surface of oxygen process, thus obtaining high power density, achieves 4.2W/m3 maximum output power of the battery body and reduces 50 percentage production cost, and is easy to mass production and low in production cost, and has wide range application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a micro-biological fuel battery manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a micro-biological fuel battery manufacturing method.'(Drawing includes non-English language text)'
