Abstract:
1. A process of manufacturing a lithium ion battery, the process comprising assembling a cathodic electrode layer and a composite structure to form a stack, the stack comprising the cathodic electrode layer, an anodic electrode layer and a separator layer between the cathodic electrode layer and the anodic electrode layer wherein the composite structure comprises the anodic electrode layer and the separator layer, wherein the separator layer comprises a porous anodized metal oxide layer containing substantially straight and parallel nanometer scale through-pores having a diameter of greater than 10 but less than 100 nm and extending through the entire thickness of the porous anodized metal oxide layer, the anodic electrode layer comprises an anodic material capable of reversibly inserting lithium, and the cathodic electrode layer comprises a cathodic material capable of reversibly inserting lithium, wherein the porous anodized metal oxide separator layer comprises an anodized metal oxide selected from the group consisting of aluminum oxide, titanium oxide, zirconium oxide, niobium oxide, tungsten oxide, tantalum oxide, and hafnium oxide, and wherein the anodic electrode layer comprises a material selected from the group consisting of vanadium, carbon, silicon, aluminum, tin, and lithium titanate.
