Characterization of Ti-doped TiO based composite electrode for lithium polymer secondary batteries.

Ti-doped TiO nanoparticles were synthesized and fabricated into a composite electrode as an anode material for lithium polymer batteries. The composite electrode contained polymer electrolyte (PE) to reduce interfacial resistance between the solid PE and electrode. The effect of PE content on the composite electrodes was analyzed by GITT, and it was found that PE significantly influenced lithium storage as well as internal resistance.

Mesoporous amorphous binary Ru-Ti oxides as bifunctional catalysts for non-aqueous Li-O batteries.

Mesoporous amorphous binary Ru-Ti oxides were prepared as bifunctional catalysts for non-aqueous Li-O batteries, and their electrochemical performance was investigated for the first time. A Li-O battery with mesoporous amorphous binary Ru-Ti oxides exhibited a remarkably high capacity of 27100 mAh g as well as a reduced overpotential. A GITT analysis suggested that the introduction of amorphous TiO to amorphous RuO was responsible for the enhanced kinetics toward both the oxygen reduction reaction and oxygen evolution reaction.
