One-step Preparation of Nanoarchitectured TiO(2) on Porous Al as Integrated Anode for High-performance Lithium-ion Batteries
Titanium dioxide (TiO(2)) is an attractive anode material for energy storage devices due to its low-volume-change and high safety. However, TiO(2) anodes usually suffer from poor electrical and ionic conductivity, thus causing dramatic degradation of electrochemical performance at rapid charge/disch...

description | Titanium dioxide (TiO(2)) is an attractive anode material for energy storage devices due to its low-volume-change and high safety. However, TiO(2) anodes usually suffer from poor electrical and ionic conductivity, thus causing dramatic degradation of electrochemical performance at rapid charge/discharge rates, which has hindered its use in energy storage devices. Here, we present a novel strategy to address this main obstacle via using nanoarchitectured TiO(2) anode consisting of mesoporous TiO(2) wrapped in carbon on a tunnel-like etched aluminum substrate prepared by a simple one-step approach. As a result of this nanoarchitecture arrangement, the anode exhibits excellent rate performance and superior cyclability. A rate up to 100 C is achieved with a high specific capacity of about 95 mA h g(−1), and without apparent decay after 8,000 cycles. |
