NOVELTY - A zinc-ion battery comprises a shell, a positive electrode column, a negative electrode column, a positive plate and a negative plate. The shell is filled with an electrolyte, and the positive plate has an activation film layer and a water-proof powder layer. A conductive network electrically connected with the positive electrode column is buried in the water-proof powder layer. The positive plate is embedded in the wall of shell. The negative plate is composed of conductive network buried in the zinc powder layer and electrically connected with the negative electrode column.    USE - Zinc-ion battery.    ADVANTAGE - The zinc-ion battery is manufactured easily, and exhibits excellent workability and charging characteristics.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of zinc-ion battery, which involves positioning positive plate and negative plate in the shell, connecting the plates with corresponding wire, filling electrolyte and packing. The negative plate is obtained by screeding the mixture of zinc powder and microcrystalline cellulose in weight ratio of 100:6-8 on battery cotton paper, embedding in the conductive network using another battery cotton paper, and press-molding. The water-proof powder is obtained by adding acetylene black and low-pressure polyethylene in weight ratio of 100:30-35 in a container, adding desired amount of kerosene, blend-heating, cooling, pressing in oil hydraulic press, crashing and filtering. The activation film is formed by adding suitable distilled water into acetylene black, activated carbon and silver nitrate in weight ratio of 100:500-550:30-35, blending, drying, locating in muffle furnace, heating at 370 plus minus 5 degrees C for 8-8.5 hours, cooling to room temperature, filtering, adding distilled water to the obtained activated powder, polytetrafluoroethylene emulsion and Emulsifier OP (RTM: polyoxyethylene octylphenol ether) in weight ratio of 100:50-55:25-26, mixing uniformly, and rolling at 40-50 degrees C to form film using absolute ethyl alcohol. The positive plate is manufactured by providing some amount of water-proof powder on the activation film, screeding, embedding in the conductive network using mold, pressing in oil hydraulic press at 170-180 degrees C, soaping in toluene for 12-13 hours, and drying.
