High-energy and high-powered lithium-ion batteries can be achieved when a high-performance multidimensional composite cathode is used.
The composite electrode structure is made up of highly-conductive 3D carbon nanotube (CNT) networks superimposed into interlaced porous LiFePO4 media via an in situ sol–gel process. Hierarchically structured composites based on porous LiFePO4 with CNT networks present significantly improved specific capacity and rate performance in comparison to unmodified porous LiFePO4 when used in lithium ion batteries.
This research has been carried out by Yingke Zhou, Zongping Shao and colleagues, at Nanjing University of Technology, in China along with a collaboration in Colorado. Why not read the article in full, published in Chemical Communications, it is free to access until the 17th September (2010).
