Dual carbon engineering enabling 1T/2H MoS2 with ultrastable potassium ion storage performance

“…5,6 Nevertheless, the size of potassium ions (with a radius of 1.40 Å) significantly exceed that of lithium ions (0.78 Å). 7 This size a Key Laboratory of Superlight Materials and Surface Technology, Ministry of difference engenders challenges during the potassiation/ depotassiation processes, inducing sluggish diffusion kinetics and enormous volume changes within the electrode material. 8 Thus, obtaining high capacity and desirable stability remains a formidable hurdle for PIBs.…”

Aromatic biomass (torch ginger) leaf‐derived three‐dimensional honeycomb‐like carbon to enhance gravimetric supercapacitor

“…The recent attention paid to the continuous improvement of supercapacitors as electrical energy storage devices, in terms of electrodes and electrolytes, is because of their advanced performance with superior energy and power capacities compared to conventional capacitors and batteries. 1 Some of these innovations include graphene, 2 graphene oxide, 3 activated carbon/porous carbon, 3 carbon aerogel, 4 conductive polymer 5 and metal oxide. 6 Activated carbon materials with unique geometries such as nanofibers, 7 nanotubes, 8 nanoballs, 9 nanosheets 10 and nano-3D 11 have become of interest due to their thermal stability and electrochemical conductivity.…”

Corn Husk‐Derived Activated Carbon as High‐Performance Anode Constituent for Rechargeable Aqueous Zn/α‐MnO2 Batteries

“…An illustration of this would be the preparation of activated carbon (AC) from biomass resources, such as different leaves, fruit peels, waste husks, trees, plant roots, and grasses. [ 22–26 ] AC derived from waste biomass is suitable for EES applications due to its porous and conductive properties, hierarchical structure, low cost, recyclability, and natural abundance of waste precursors. [ 22 ] Several biomass precursors have been utilized until now to derive carbon‐based battery materials such as sorghum in K‐ion battery, sugarcane in Na‐ion battery, and corn cob in Li‐ion battery.…”

“…[ 22 ] Several biomass precursors have been utilized until now to derive carbon‐based battery materials such as sorghum in K‐ion battery, sugarcane in Na‐ion battery, and corn cob in Li‐ion battery. [ 23–25 ] The internal pores of carbon‐based materials get activated during the activation process due to the removal of contamination and impurities (raw natural fibers, silica, and biomass ash) providing the high surface area and porous network. [ 26 ] To produce AC from waste biomass, a variety of activation mechanisms was used such as catalytic, physical, chemical, and microwave activation.…”
