TL;DR: Using nitrogen-doped graphene produced by a simple plasma process, ultracapacitors are developed whose capacitances are about 4 times larger than those of pristine graphene based counterparts without sacrificing other essential and useful properties for ultracAPacitor operations including excellent cycle life, high power capability, and compatibility with flexible substrates.

TL;DR: This study shows that MOFs made as nanocrystals (nMOFs) can be doped with graphene and successfully incorporated into devices to function as supercapacitors.

TL;DR: Nitrogen doping enables unprecedented cell performance by engaging anomalous electrochemical phenomena such as nanoparticles division into even smaller ones, their agglomeration-free diffusion between nitrogen-doped sites as well as capacity rise with cycles.

TL;DR: The single crystal X-ray diffraction structure of the Fe-CAT-5 shows bound sulfate ligands with DMA guests residing in the pores as counterions, and thus ideally suited for proton conductivity.

TL;DR: In this article, ultrathin vanadium pentoxide (V2O5) nanowires were uniformly incorporated into graphene paper to overcome the agglomeration issue, which enabled substantially improved cycle life.
