Abstract: Increasing upper cut-off voltage is capable of achieving higher charge capacity whereas this strategy always causes a dramatic degradation of cycling and thermal stability. In this study, we first report spinel LiNi0.5Mn1.5O4-modified LiCoO2 ([email protected]) as… read more here.

Abstract: In this study, the effects of charge/discharge cycling on the thermal stability of LiNi0.8Co0.1Mn0.1O2, a high-Ni cathode material, are systematically investigated. X-ray diffraction measurements show that there is almost no change in the bulk structure… read more here.
