The emerging fields of electric vehicles and renewable energies demand significant improvements in Li-ion battery technologies. To enhance the energy and power densities of Li-ion batteries, high capacity Si anodes and high power LiFePO4 cathodes, with long cycle life, were investigated. Self-aligned Si and LiFePO4 nanorods were fabricated on a genetically-modified Tobacco mosaic virus (TMV) template and shown both improved Li+ and electronic conductance. Specifically, TMV templated Ni nanorods were directly attached to the main current collector in a near-vertical manner.    The sequential layering of active materials creates a unique architecture where the highly conductive Ni layers act as nano-scale current collectors connecting the electrochemically active species covering each virus nanorod directly to the main current collector.   TMV enabled Si nanorod anodes and LiFePO4 nanorod cathodes demonstrated exceptionally high capacity and cycling stability
