| titleOfInvention | Preparation method of organic salt coated lithium iron phosphate cathode material |
| abstract | The invention relates to a preparation method of an organic salt coated lithium iron phosphate anode material, which comprises the following steps: (a) dissolving an organic salt in a solvent to prepare an organic salt solution; (b) adding lithium iron phosphate into the organic salt solution for mixing, and then heating the solution under the condition of continuous stirring until the solvent is completely volatilized; the chemical general formula of the organic salt is Wherein R is hydrogen, alkyl, hydrocarbyl or alkyl chain containing alkenyl or/and carboxylate. Thus, the coating layer can be ensured not to be dissolved and not to fall off in the electrode slice preparation and the battery electrochemical circulation process; when the molecular formula of the lithium iron phosphate composite material contains conjugated carbon-carbon double bonds, a lithium ion transmission channel can be formed, the migration rate of lithium ions on the surface of the electrode is improved, the effective contact of electrolyte and a carbon coating layer on the surface of the electrode is prevented, the erosion of the electrolyte to an electrode material in the electrode circulation process is inhibited, and the stability of a lithium iron phosphate structure is ensured. |
