The cycle performance of graphite/Li(Ni,Co,Mn)O 2 battery coated with and without Al 2 O 3 positive active material was studied comparatively, including charge–discharge curve, capacity, discharge curve at 0.2C rate of 25°C, and impedance. The results show that the coating can obviously ...
The electrocatalytic reduction of CO2 to C2H4 is a topic of great interest. It is known that the preparation of efficient catalysts for this transformation is the key factor that determines the yield of C2H4. In this study, we prepared 1-octyl-3-methylimidazole functionalized graphite sheets (...
