High‐Performance Supercapacitors: In Situ Synthesis of Vertical Standing Nanosized NiO Encapsulated in Graphene as Electrodes for High‐Performance Supercapacitors (Adv. Sci. 3/2018)

In article number 1700687, Junlei Qi, Jian Cao, and co-workers report the development of vertical-standing nanosized NiO encapsulated in graphene as electrodes for high-performance supercapacitors. The resultant NiO encapsulated in high-quality graphene layers as electrodes can exhibit a high specific capacity, good rate capability, and excellent cycling performance because of the integrated structures of NiO nanoparticles, the high-quality graphene layers, and the vertical-standing nanosheets.
