“…It retained a capacitance of 114 F g -1 (12.8 lF cm -2 ) at a higher current density of 30 A g -1 . The results are higher than those for the reported carbon materials templated such as mesoporous-activated carbon spheres(204 F g -1 at 0.5 A g -1 ) [34], coconut kernel-derived activated carbon (173 F g -1 at 0.25 A g -1 ) [35], template carbon materials(180 F g -1 at 0.625 A g -1 ) [36], and ZIF-derived porous carbon (228 F g -1 at 0.1 A g -1 ). [37] The electrochemical long-term cyclic stability of the highly mesoporous carbons and their repeatability was investigated by GCD measurement.…”

This paper presents the direct synthesis of highly porous carbons via the carbonization of potassium humate in inert atmosphere without any activation. Carbonization temperature is important for carbon structures and their electrochemical performance in electric doublelayer capacitors. The CK800 material derived from potassium humate has a high-specific surface area of 890 m 2 g -1 and an ideal average pore size of 2.56 nm. The CK800 material can also deliver a high-specific capacitance of 232 F g -1 (26.1 lF cm -2 ) at a constant charge/ discharge current of 0.5 A g -1 . This capacitance is maintained at a value of 114 F g -1 (12.8 lF cm -2 ) at 30 A g -1 . This material also has good cycle stability with over 93.5 % capacitance retention after 5000 cycles when measured in a three-electrode system using 6 M KOH as electrolyte. In this study, the CK800 material is tested in a three-electrode system using 1 M NaHCO 3 as electrolyte. Operational voltage in 1 M NaHCO 3 aqueous solution could be extended up to 1.3 V.

“…In addition, biomass contains more active substances, which can provide a natural heteroatom source for carbon materials, making the prepared carbon materials themselves contain a large number of heteroatoms such as N, O, S, P, etc . For these reasons, so far researchers have turned almost every conceivable biomass on earth into carbon for supercapacitors …”

In this paper, we developed a simple strategy for preparing three‐dimensional porous carbon from xylose mother liquor for high‐performance supercapacitors. Through simple regulation of activation temperature, the porous carbon prepared under optimized conditions have a perfect honeycombed structure with fewer layers and co‐existing macropores, mesopores and micropores. The product also has high content of self doped hetero‐atoms of O (10.2 at%) and N (0.5 at%). The constructed supercapacitors based on this porous carbon exhibited excellent performance with fantastic specific capacitance of 544 F/g at 0.5 A/g, excellent rate performance of 260 F/g at 20 A/g, as well as long cycle stability of 90.2% capacitance retention after 10000 cycles at 10 A/g in 6 M KOH in three‐electrode systems. Notably, symmetric supercapacitors exhibited energy density of 22.3 Wh kg−1 at a power density of 448 W kg−1 in the aqueous electrolyte Na2SO4, and a even higher specific energy density of 42.8 Wh kg−1 was achieved at a high power density of 749.8 W kg−1 in the organic electrolyte Et4NBF4.
