Abstract

A method for preparing an anode material for lithium-ion batteries, the method including: (1) mixing a raw residue from a biomass gasifier and an aqueous solution including a surfactant to yield a mixed solution, grinding the mixed solution to disperse the raw residue, washing the mixed solution using water to remove the surfactant, leaching the mixed solution, to yield a first intermediate residue; (2) adding hydrochloric acid to the first intermediate residue, stirring to remove impurities, filtering, and washing the residue to be neutral, to yield a second intermediate residue; (3) adding polyethyleneimine and ethanol to the second intermediate residue, shaking, washing away the polyethyleneimine and the ethanol, filtering, to yield a third intermediate residue; and (4) adding nitric acid to the third intermediate residue, fully stirring, washing away the nitric acid, filtering and drying, to yield the anode material for lithium-ion batteries.
