摘要： A lithium-ion battery having an anode including an array of nanowires electrochemically coated with a polymer electrolyte, and surrounded by a cathode matrix, forming thereby interpenetrating electrodes, wherein the diffusion length of the Li+ ions is significantly decreased, leading to faster charging/discharging, greater reversibility, and longer battery lifetime, is described. The battery design is applicable to a variety of battery materials. Methods for directly electrodepositing Cu2Sb from aqueous solutions at room temperature using citric acid as a complexing agent to form an array of nanowires for the anode, are also described. Conformal coating of poly-[Zn(4-vinyl-4′methyl-2,2′-bipyridine)3](PF6)2 by electroreductive polymerization onto films and high-aspect ratio nanowire arrays for a solid-state electrolyte is also described, as is reductive electropolymerization of a variety of vinyl monomers, such as those containing the acrylate functional group. Such materials display limited electronic conductivity but significant lithium ion conductivity. Cathode materials may include oxides, such as lithium cobalt oxide, lithium magnesium oxide, or lithium tin oxide, as examples, or phosphates, such as LiFePO4, as an example.
