摘要：

Electrochemical activities of layered LiCrO2 (R-3m) and NaCrO2 (R-3m) materials were investigated at room temperature in aprotic organic electrolyte solutions. LiCrO2 and NaCrO2, possessing the same polytypism and the same transition metal atom, were inactive and active in 1 mol dm(-3) LiClO4 and NaClO4 propylene carbonate, respectively. The NaCrO2 electrode performed the highly reversible capacities of ca. 120 mAh g(-1) with satisfactory capacity retention in a Na cell. (C) 2010 Elsevier B.V. All rights reserved.
