ABSTRACT WITHDRAWN

Spinel Li4Ti5O12 has become an alternative anode material for graphite in lithium ion batteries for large scale electrical energy storage in terms of solving safety issues and improving battery life-time. In order to form a much more bonding between the LTO and current collector, which is beneficial for stable cycling and high rate performance, we introduce a wrinkled graphene between the electrode layer and aluminum current collector to improve the rate performance and cycling performance of Li4Ti5O12 electrode. The introduced wrinkled graphene layer provides larger contact area, lower contact resistance, stronger adhesion and better electrode stability of Li4Ti5O12 electrode. This excellent electrochemical performance and very simple preparation method makes LTO@G-Al electrodes suitable for high-rate lithium ion batteries.
