The application relates to a polyanion sodium ion battery positive electrode composite material, and belongs to the technical field of sodium ion batteries. The chemical expression of the positive electrode composite material is sintered by compounding and sintering of specific design carbon-doped potassium pyrophosphate iron powder and a sodium pyrophosphate iron phosphate matrix. The carbon-doped potassium pyrophosphate iron is prepared by a vacuum calcination process by using a structure control agent synthesized by p-ethylphenylthiophenol and triallylamine, and the unique space symmetry structure can chelate iron and potassium ions at the molecular level, form a uniform precursor, and produce an ultra-microstructure wrapped by an edge brittle carbide after calcination. The composite material constructs a continuous three-dimensional electron conductive network and a long-range ion channel in the NFPP matrix, forms an ion conductivity transition zone at the phase interface, significantly improves the ion migration efficiency, and effectively solves the technical bottleneck of poor high-rate performance of the NFPP material.

The invention relates to a polyanion sodium ion battery positive electrode composite material, and belongs to the technical field of sodium ion batteries. The chemical expression of the positive electrode composite material is as follows: the positive electrode composite material is formed by compounding and sintering specifically designed carbon-doped potassium ferric pyrophosphate superfine powder and a ferric sodium pyrophosphate matrix. Wherein the carbon-doped potassium ferric pyrophosphate is prepared by adopting a structure control agent synthesized by p-ethyl thiophenol and triallylamine through a vacuum calcination process, the unique space symmetric structure of the carbon-doped potassium ferric pyrophosphate can be chelated with iron and potassium ions on a molecular level to form a uniform precursor, and an ultrastructure wrapped by edge brittle carbides is generated after calcination. According to the composite material, a continuous three-dimensional electronic conductive network and a long-range ion channel are constructed in an NFPP matrix, and an ion conductivity transition region is formed on a phase interface, so that the ion migration efficiency is remarkably improved, and the technical bottleneck of poor high-rate performance of the NFPP material is effectively solved.
