摘要：

Orthorhombic LiMnO2 with small grain size was successfully synthesised using a one-step middle-temperature solid-state reaction (OSSS). Compared with the methods other researchers used, the OSSS method is much simpler. It is a one-step method without intermediate regrinding or other treatments. The o-LiMnO2 obtained showed a high initial capacity 180 mAh/g when cycled at a current density of 0.5 mA/cm(2) at room temperature, and the rate capability was improved due to the smaller particle size. Therefore, the one-step middle temperature solid-state reaction could be a promising method for o-LiMnO2 compound synthesis. (C) 2002 Elsevier Science B.V. All rights reserved.
