TL;DR: In this article, Nitrogen-enriched nonporous carbon materials derived from melamine-mica composites are subjected to ammonia treatment to further increase the nitrogen content and are tested as electrodes for supercapacitors, and in acidic or basic electrolytes, the gravimetric capacitance of treat samples is three times higher than that of untreated samples.

TL;DR: In this article, the performance of electric double layer capacitors in nonaqueous electrolyte of a series of alkaline agent-activated carbons with high surface area is presented. And the results obtained in this study confirm that capacitance not only depends on surface area, but also on pore size distribution and surface chemistry.

TL;DR: In this paper, the surface film formed on lithium immersed in propylene carbonate or {gamma}-butyrolactone containing 1.0 mol/dm{sup 3} LiBF{sub 4}(LiBF{ sub 4}/THF) for three days consists of LiF and a small amount of organic compounds.

TL;DR: In this article, X-ray photoelectron spectroscopy and scanning electron microscopy methods were used for analysis of the surface layers of lithium deposited at various current densities from propylene carbonate containing 1.0 ml/dm{sup 3} LiClO{sub 4} and various amounts of HF, to investigate the effect of HF in electrolytes on the surface reaction of lithium during electrochemical deposition.

TL;DR: The double layer capacitance of highly pure single-walled carbon nanotubes (SWCNTs) prepared by the HiPco(TM) process was measured in 1.0 mol dm(-3) LiClO4/propylene carbonate solution.
