| titleOfInvention | Preparation LiFe xm 1-xpO 4the method of/C lithium ion composite positive pole |
| abstract | The invention discloses a kind of method of production anode material for lithium-ion batteries of low cost, described anode material for lithium-ion batteries basic structure formula is LiFen x mn 1-x pOn 4 , wherein metallic element M can be manganese, cobalt, nickel or its mixture.This positive electrode is olivine-type crystal structure, and it has relative to LiFePOn 4 the discharge voltage plateau that material is higher and energy density.Said method comprises the following steps for the production of the process of positive electrode: (1) makes the soluble compound being selected from molysite, metal M salt and phosphorous acid group react in the basic conditions to generate to precipitate to collect and washs the dry nanoscale presoma obtaining iron content and metal M under water, the aqueous solution or solvent existent condition; (2) nanoscale presoma is mixed with lithium salts presoma, and be mixed into carbon matrix precursor, and after nanometer and dry process, calcining generates LiFe under inertia or reproducibility environmentn x mn 1-x pOn 4 / carbon composite anode material.Wherein x value is between 0 ~ 1.Another object of the present invention is to provide a kind of electro-chemical activity positive electrode of low cost of being produced by described method.The electro-chemical activity positive electrode manufactured thus can be used for manufacturing electrode and battery. |
