Red phosphorus and black phosphorus anodes have very similar lithiation/sodiation reaction mechanism, both of which can form Li3P/Na3P in a fully discharged state, thus having a high theoretical specific capacity of 2596 mAh/g [59,60,61]. Unlike lithiation in red phosphorus, which only involves a one-step synthesis. Black phosphorus has great potential as an electrode material, but its anisotropic ion diffusion path causes a negative effect on lithium/sodium storage performance. Additionally, anisotropic volume. One isoform of phosphorus, blue phosphorus, is receiving more attention in recent years because of its special structure and electrochemical characteristics. Unlike graphene, blue phosphorus has a.
