| 英文摘要 | The formation of impurity LixNi1-xO when synthesizing spinel LiNi0.5Mn1.5O4 using solid state reaction method, and its influence on the electrochemical properties of product LiNi0.5Mn1.5O4 were studied. The secondary phase LixNi(1-x)O emerges at high temperature due to oxygen deficiency for LiNi0.5Mn1.5O4 and partial reduction of Mn4+ to Mn3+ in LiNi0.5Mn1.5O4. Annealing process can diminish oxygen deficiency and inhibit impurity LixNi1-xO. The impurity reduces the specific capacity of product, but it does not have obvious negative effect on cycle performance of product. The capacity of LiNi0.5Mn1.5O4 that contains LixNi1-xO can deliver about 120 mAhg(-1). (C) 2011 Elsevier B.V. All rights reserved. |
