▎ 摘　　要

NOVELTY - Preparing porous iron-based phosphate lithium battery material comprises (i) mixing manganese, iron, phosphorus and ball-milling according to the ratio required by the product to obtain mixed powders, where the mole number of manganese is 35-60%, (ii) obtaining the mixed powder by arc melting to obtain a Mn-Fe-P ternary alloy, (iii) adding an etchant to etch the ternary alloy to obtain a FeP porous precursor, (iv) soaking the above-mentioned porous precursor material with ethanol, and obtaining a filter cake by a solid-liquid separation method, and placing the filter cake in a vacuum environment to dry to obtain the dry powder of the porous precursor material, (v) mixing the dry powder of the precursor material with the lithium source and the carbon source, calcining at 650-850°C for 10-25 hours in a nitrogen atmosphere, and crushing. USE - The method is useful for preparing porous iron-based phosphate lithium battery material. ADVANTAGE - The material effectively adsorbs ethanol and improves the conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for porous iron-based phosphate lithium battery material prepared by the above method. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the method for preparing porous iron-based phosphate lithium battery material (Drawing includes non-English language text).
