Due to diminishing available petroleum resources, alternative sources of power storage have become ever more necessary. Since the discovery of lithium-ion batteries in the 1970s and the first commercialized material (lithium cobalt oxide), research in this field has exploded. Herein is described the synthesis methods and morphologies of several lithium iron phosphate morphologies, one of which is lithium iron phosphate nanobelts, along with the synthesis of pyridine functionalize graphene. The crux of which involves maximization of the primary channel of lithium-ion diffusion within the material via excess chloride, an ion which lends to inhibiting particle growth of the material in the <010> direction, within the precursor solution, as well as maximizing the aspect ratio of the material, and subsequently modifying the material with nitrogen-doped graphene materials to act as a conducting agent. Additionally is explored the effectiveness of a copper titanate anode. Finally, a cholesterol oxidase biosensor is discussed.
