The benefits of the conformal coating of polyethylene oxide (PEO)-based polymer electrolyte by the electropolymerization technique on titania nanotubes (TiO(2)nts) are highlighted. Due to the presence of polymer electrolyte coating the nanotubes, the capacity of the half cell is improved by 45% at 1 C compared to bare TiO2nts. The polymer-coated TiO2nts in the full cell deliver an average capacity of similar to 30 mu A h cm(-2) (120 mA h g(-1)) with LiNi0.5M1.5O4, similar to 25 mu A h cm(-2) (100 mA h g(-1)) with LiFePO4 and similar to 23 mu A h cm(-2) (90 mA h g(-1)) with LiCoO2, respectively during 50 cycles.
