Abstract

Ni(core)/TiO₂(shell) nanocomposite anodes were fabricated on three-dimensional, self-assembled nanotemplates of Tobacco mosaic virus using atomic layer deposition, exhibiting high capacities and rate capability and extremely low average capacity fading (∼0.024% per cycle) for ∼1000 cycles.
