Abstract

The invention discloses a doping type lithium battery anode material. The doping type lithium battery anode material contains the following components in percentage by weight: 92wt%-96wt% of a ternary material and 4wt%-8wt% of a doping material, wherein the doping material is a mixture of at least two of ferrous sulfide, manganese sulfide and titanium disulfide. The doping type lithium battery anode material is high in monomer energy density, the electrode polarization phenomenon after a lithium battery is repeatedly charged at a high temperature is relatively high, and the working time and service life of the lithium battery at high temperature can be effectively prolonged.
