▎ 摘　　要

NOVELTY - Preparing nano hybrid material comprises (i) preparing n-hexane solution of Mx(oleate)y by chemical substitution reaction, then stirring and adding silicon and reduced graphene oxide to obtain precursor solution, then evaporating by rotary evaporation to obtain final precursor, where the silicon-based material is a silicon nanosphere, silicon nano-rods, silicon nano-wires, silicon nanotubes and hollow silicon nanoparticles, and (ii) heating the precursor obtained in step (i) in an inert atmosphere to obtain (silicon/manganese(II) oxide)/carbon/ reduced graphene oxide nano-hybrid material. USE - Nano hybrid material in long-circulating lithium ion battery material (claimed). ADVANTAGE - Nano hybrid material has integrated positive/negative cyclical effects(claimed); and has simple preparation process and low production cost.
