Mesoporous carbon nanoparticles (MCNPs) with an average particle size of 27.3 nm and a pore size of 3–5 nm were facilely synthesized in ultrahigh yield (91.7 wt%) and used as a high-performance lubricant additive for polyethylene glycol (PEG200).
Combining interfacial methods and mesoporous carbon channels, an asymmetric device, using N,S-codoped mesoporous carbon and a MnO2@MC-30 core shell composite, is assembled with high energy, power densities and outstanding cycling stability.
