摘要：

In this paper, electrochemical investigation of LiNiO2 films prepared by molten salt synthesis (MSS) method was performed to develop a storage electrode of solar cell energy. The preferred orientation constantly indicates (111), (012), (110) and (113). The microstructures confirmed the size of the LiNiO2 particles in a narrow range of similar to 200 nm. Cyclic voltammogram (CV) profiles have broad cathodic peak at 3.7 V and three anodic peaks at 3.4, 3.1 and 1.9 V. For the charge and discharge range of 2.5-4.4 V, the discharge capacity was 159 mAh/g at first, and slowly decreased to 148 mAh/g during the 30th cycles. (C) 2009 Elsevier B.V. All rights reserved.
