Abstract

As new substrate materials to replace a conventional carbon substrate, TiO ₂ and Nb-doped TiO ₂ air-electrodes for Li-air batteries were investigated. Through a simple two-step process, we successfully synthesized anatase Nb-doped TiO ₂ nanoparticles and demonstrated the potential applicability of TiO ₂ -based materials for use in Li-air battery electrode. An air-electrode with Nb-doped TiO ₂ nanoparticles could deliver a higher discharge capacity than a bare TiO ₂ electrode due to the enhanced conductivity, which implies the importance of facile electron transport during the discharge process.
