Peanut shell derived hard carbon as ultralong cycling anodes for lithium and sodium batteries

Enhanced Lithium Storage in Hierarchically Porous Carbon Derived from Waste Tea Leaves

“…This capacity increase phenomenon has already been reported in previous studies involving rich hush-derived carbon23, peanut shell derived hard carbon28, and Portobello mushroom-derived porous carbon47. It can be primarily attributed to the hierarchically porous carbon structure resulting from acid treatment, suggesting that various unexposed micro- and mesopores are more accessible during repeated cycling.…”

“…As an available natural resource, biomass has recently attracted a great deal of attention for use in the preparation of carbon anode materials owing to ease of access, eco-friendliness, and low cost. Thus, the use in LIBs using carbon obtained from biomass waste has been explored with sources as diverse as rice husks, mangrove charcoal, wheat stalk, banana peels, cherry stones, and peanut shells2122232425262728. The electrochemical properties of such materials are critically dependent on the optimization of the preprocessing procedure, pyrolysis temperature, and reaction time to control product crystallinity, morphology, and porosity2930.…”

A Novel 2D Porous Print Fabric-like α-Fe2O3 Sheet with High Performance as the Anode Material for Lithium-ion Battery

“…9b) assigned to the characteristic peak of esters carbonyl [42]. [45,46], we deduce the alkali ammonia solution here may be also used as the porogen. Thanks to the capillarity-driven infiltration of liquid ammonia, a large number of pores can be penetrated into the activated flower spikes of Thyphas orientalis, which is helpful for the growth of α-Fe 2 O 3 nanocrystals.…”

Impact of the Acid Treatment on Lignocellulosic Biomass Hard Carbon for Sodium‐Ion Battery Anodes

“…In line with the low-cost and sustainability issues, [38,39] biomass-derived hard carbons play akey role in the development of SIBs. [44][45][46][47][48] Nonetheless,c urrent studies on hard carbon anodesm ainly focus on morphology control, [49] heteroatom-doping, [50,51] and annealing temperature regulation.
