摘要：

Layered single-crystalline LiNi0.5Mn0.5O2 nanostructures were synthesized through a citric acid-assisted sol-gel method. The results of XPS match well with the expected stoichiometric formula (Ni0.5Mn0.5IV)-Mn-II. Electrochemical tests show that it delivers a large discharge capacity of 160.7 mA h g(-1) vs. Li metal at 0.2 mA cm(-2) (voltage window 2.5-4.5 V). (C) 2004 Elsevier B.V. All rights reserved.
