▎ 摘　　要

NOVELTY - A nickel based metal organic framework-melamine-graphene foam compressible composite material is prepared by coating compressible composite material with graphene to form melamine foam network, calcining and adsorbing two-dimensional nickel-based metal organic framework. USE - Nickel based metal organic framework-melamine-graphene foam compressible composite material for use in zinc-air battery (claimed) as positive electrode material. ADVANTAGE - The nickel based metal organic framework-melamine-graphene foam compressible composite material has high conductivity, specific surface area, rich catalytically active sites and direct contact with melamine-graphene carbon foam, promotes diffusion of electrolyte and charge transfer and is prepared by not utilizing special device at large scale under easily controlled conditions. The zinc-air battery has large capacity and better flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing the nickel based metal organic framework-melamine-graphene foam compressible composite material.
