Abstract
The LiCoO2 compound with trigonal structure (R-3m), is the most common positive electrode material used in Li-ion batteries. In this paper, we report nanoprobe electron diffraction results of two surface phases in LiCoO2 formed by two different heat treatments conditions. The nanoprobe diffraction patterns were taken at 200 kV with a Topcon TEM and using a 5nm probe size of convergence semi-angle α=2.4 mrad. Kinematical simulations of the nanoprobe diffraction patterns were done using JEMS program [1]. The diffraction patterns were analyzed with respect to published crystallographic data of stoichiometric LiCoO2 and Li deficient LixCoO2 phases [2, 3].
