▎ 摘　　要

NOVELTY - The method involves adding the graphene into the second solvent to disperse to prepare the graphene graphene mixing and dispersing the conductive silver paste and the third solvent according to the mass ratio of 1: (10-20), where the conductivity silver paste diluent is prepared. The first, second and third solvents are dissolved in each other and do not generate chemical reaction, and the pH of the second and second solvent can be graphene, and pH of third solvent is neutral. The conductive carbon material is acetylene carbon black, carbon fibre, pyrolytic carbon, foam graphite, conductive carbon black, crystalline flake graphite and expanded graphite. USE - Preparation method of water activated magnesium primary battery positive electrode. ADVANTAGE - The method improves the heating problem of the battery in the using process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a water-activated magnesium primary battery positive electrode.
