摘要
Truly long-life: A LiFePO4/carbon composite containing a highly crystalline LiFePO4 core witha size of about 20-40 nm and a semi-graphitic carbon shell with a thickness of about 1-2 nm provides bothh igh power and very long cycling life (see picture). The synthetic method can be extended to the preparation of other materials, such as Li4Ti 5O12/carbon and Mn3O4/carbon composites. (Graph Presented) © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
