Abstract
LiCo1-xMxO2 materials, having the layered α-NaFeO2 type structure, are promising cathodes for advanced lithium batteries. Their good performance is very much conditioned by the presence of a good lamellar structure that needs to be stable enough to stand many charge/discharge cycles. In our case, we focus on LiCo1-xMxO2 samples (M=Ni, A1) prepared by a low temperature route: we synthesize them by a sol-gel method using succinic acid as chelating agent. We study the details of their crystallographic structure by XRD, we analyse their chemical composition by ICP and get information about the morphology of the powders by SEM. Also, we carry out a study of their local structure by means of FTIR spectroscopies. Finally, we show the results of the electrochemical studies of the Li//LiNi0.5-xAlxCo0.5O2 prepared cells
