摘要
(Figure Presented) A new electrode material that is expected to have promising applications in energy storage and energy-harvesting systems is presented. In this material, which consists of Ca3Co 4O9 nanoplates with a high theoretical gravimetric capacity, the lithium-driven conversion process results in the formation of active/inactive nanocomposite electrodes that mitigate the aggregation of the active nanometals (see picture). © 2007 Wiley-VCH Verlag GmbH & Co.
