A positive electrode includes a lithium-based active material, a binder, a conductive filler, and discrete aluminum oxide nanomaterials. The aluminum oxide nanomaterials are mixed, as an additive, throughout the positive electrode with the lithium-based active material, the binder, and the conductive filler. The positive electrode with the discrete aluminum oxide nanomaterials may be incorporated into a lithium ion battery. The aluminum oxide nanomaterials may be formed by the following method. A solution is formed by mixing an aluminum oxide precursor and an acid. A carbon material is added to the solution, thereby forming an aqueous mixture having the carbon material therein. Hydrothermal synthesis is performed using the aqueous mixture, and precursor nanostructures are grown on the carbon material. The precursor nanostructures on the carbon material are annealed so that the carbon material is removed and aluminum oxide nanomaterials are formed.
