Cherry stones as precursor of activated carbons for supercapacitors

It is shown that cherry stones-wastes can be recycled as activated carbons for electrode material in supercapacitors. KOH-activation of this precursor at 800-900oC is an efficient process to obtain carbons with large specific surface areas (1100-1300 mg), average pore sizes around 0.9 to 1.3 nm, which makes them accessible to electrolyte ions, and conductivities between 1 and 2 S cm. These feat...

Carbon-enriched coal fly ash as a precursor of activated carbons for SO2 removal.

Carbon-enriched coal fly ash was evaluated in this work as a low-cost adsorbent for SO2 removal from stack gases. The unburned carbon in coal fly ash was concentrated by mechanical sieving and vegetal oil agglomeration. The carbon concentrates were activated with steam at 900 degrees C in order to develop porosity onto the samples. The performance of these samples in the SO2 abatement was teste...

Mechanochemistry-assisted synthesis of hierarchical porous carbons applied as supercapacitors

A solvent-free synthesis of hierarchical porous carbons is conducted by a facile and fast mechanochemical reaction in a ball mill. By means of a mechanochemical ball-milling approach, we obtained titanium(IV) citrate-based polymers, which have been processed via high temperature chlorine treatment to hierarchical porous carbons with a high specific surface area of up to 1814 m2 g-1 and well-def...

Optimization of the characterization of porous carbons for supercapacitors

The optimization of carbon-based supercapacitors is of great technological importance for electrical energy storage. This challenge stresses the relevance of current attempts to increase the surface-related capacitance C/S (F m) of carbons. We show that for microporous carbons this property is practically constant for pore widths between 0.7 and 1.8 nm. The study is based on two independent app...

Enhanced life-cycle supercapacitors by thermal treatment of mesophase-derived activated carbons

This paper studies the effect of thermal treatment on the long-term performance of carbon-based supercapacitors. Two active electrode materials were studied: a mesophase derived activated carbon (AC), rich in oxygen functionalities, and an activated carbon obtained from treating AC at 1000 °C (AC-1000), from which most of the functionalities had been removed. Up to 10,000 cycles were performed ...
