Preparation of Li_(4/3)Ti_(5/3)O_4 Thin Film Anode with High Electrochemical Response for Rechargeable Lithium Batteries by Sol-Gel Method

摘要

A stoichiometric spinel Li_(4/3)Ti_(5/3)o_4 thin film was prepared by a sol-gel method with poly(vinylpyrrolidone) (PVP) as an anode of rechargeable lithium micro-batteries. The prepared film was evaluated electrochemically by cyclic voltammetry (CV). One-time-coated thin film had 0.4 #mu#m of thickness and showed high electrochemical response until 50 mV s~(-1). In this study, it was first reported that a thin film electrode with high electrochemical response obtained by the sol-gel method with PVP.
