Abstract

Ti3+-doped TiO2 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. A composite electrode was fabricated into a pouch type cell and exhibited a capacity of 160 mAh g-1 in the bent state, demonstrating the applicability of the Ti3+-doped TiO2 based composite electrode in lithium polymer secondary batteries.
