Explosion-proof composite wall and application thereof in storage battery isolation protection

The invention discloses an anti-explosion composite wall which is formed by compounding concrete blocks, calcium silicate boards and expanded perlite powder. The calcium silicate plates are vertically arranged at intervals; the concrete blocks are piled on the outer side and the upper portion of the periphery of the calcium silicate board to form a concrete protective layer, and a gap is reserved between the concrete protective layer and the calcium silicate board; the expanded perlite powder is filled in gaps between the calcium silicate boards and between the concrete protective layer and the calcium silicate boards; the concrete block is prepared from the following raw materials: cement, composite fibers, gravel, gravel, silica fume, diatomite, a polycarbonate grafted copolymer, an alkynylated graphene/palladium composite material, nano calcium carbonate powder, a coupling agent and water. The anti-explosion composite wall body is prepared by taking the concrete building blocks, the calcium silicate boards
