Controllable Fabrication of Multi-tiered Nanoporous Anodic TiO2-TiN Composite Films as High-Performance Anode Materials for Lithium-Ion Batteries

A novel nanoporous anodic TiO2-TiN composite film with a nanolaminated structure was achieved by anodizing Ti foil in an aqueous ammonia nitrate electrolyte as a promising high-performance anode material for LIBs.
