NOVELTY - Conductive coating comprises aqueous emulsion and conductive functional material; the aqueous emulsion comprises resin, coupling agent and emulsifying agent. USE - The conductive coating is useful for battery shell (claimed). ADVANTAGE - The coating can improve the contact area of the battery shell and the anode ring, increases the current collecting effect and conductivity, can reduce the diffusion of the metal element of the battery in the battery shell for a longtime storage period; improves the long-term storage discharge performance of the alkali manganese battery and greatly reduces the liquid leakage rate after the long-term storage of the batter. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing conductive coating comprising (1) mixing the resin, coupling agent, wetting agent, emulsifying agent and solvent to obtain aqueous emulsion, (2) adding conductive functional material into the aqueous emulsion and mixing to obtain the conductive coating; (2) battery shell comprising shell and conductive paint; and (3) battery comprising battery shell, preferably, the battery is an alkali manganese batter.
