Sodium ion secondary battery anode material and preparing method and application thereof

Abstract

The invention discloses a sodium ion secondary battery anode material, and a preparing method and application thereof. The material is an amorphous carbon material, and is obtained by performing high-temperature pyrolyzing on coal as a main raw material, the material is prepared by using coal and a hard carbon precursor as raw materials, mechanical mixing after adding a solvent, drying, and crosslinking, curing and pyrolyzing under an inert gas atmosphere, or prepared by using coal as a raw material, and pyrolyzing under an inert gas atmosphere. The sodium ion secondary battery prepared from the amorphous carbon material as anode material has lower cost and higher work voltage, and is stable in cycle and good in safety.
