Supercapacitors: Cross‐Coupled Macro‐Mesoporous Carbon Network toward Record High Energy‐Power Density Supercapacitor at 4 V (Adv. Funct. Mater. 51/2018)

In article number 1806153, Ning Wang, Weizhong Qian, Wei Chu, and co-workers develop an unique macromesoporous coupled carbon framework via a NaNO3-template strategy from a biopolymer aerogel. The suitable pore size of the carbon electrode expedites the fast diffusion of EMIBF4 ionic liquid electrolyte in a 4 V supercapacitor, and enables extraordinary energy-power density performance.
