Abstract

A method for preparing a electrode composite material includes providing an aluminum nitrate solution and introducing a number of electrode active material particles into the aluminum nitrate solution, mixing the plurality of electrode active material particles with the aluminum nitrate solution to form a mixture, and adding a phosphate solution into the mixture to react with the aluminum nitrate solution and form an aluminum phosphate layer on surfaces of the electrode active material particles. Lastly, the electrode active material particles with the aluminum phosphate layer formed on the surfaces thereof are heat treated.
