A new carbonaceous material derived from biomass source peels as an improved anode for lithium ion batteries

Bean-dreg-derived carbon materials used as superior anode material for lithium-ion batteries

“…The reversible capacity is still as high as 595 mAh g -1 after 500 cycles cycled under 1 C rate, which represents only 92.5% capacity retention. To our knowledge, this excellent rate capability is much better than that of some biomass-derived anodes of lithium ion batteries [55][56][57].…”

High-defect hydrophilic carbon cuboids anchored with Co/CoO nanoparticles as highly efficient and ultra-stable lithium-ion battery anodes

“…2b) exhibit two characteristics of carbon peaks, the graphitic carbon peak (G band) located at $1593 cm À1 and the disordered carbon peak (D band) at $1371 cm À1 . [39][40][41] In the spectrum of the PCC-CoO x sample, four peaks are also observed at $673, $609, $516, and $473 cm À1 , matching with A 1g , F 2g , F 2g , and E g modes of CoO. 42 The peak area ratio between the D and G bands (I D /I G ) is $1.11, which is higher than that of the amorphous PCC ($0.95), suggesting that more structural disorder is introduced into the composite during the impregnation process and thermal treatment.…”

From grass to battery anode: agricultural biomass hemp-derived carbon for lithium storage

“…The capacity of 190 mA h g À1 at the 100 th cycle with stable capacity retention indicates that natural hemp reversibly delivers 0.51 lithium per 6 carbons. For the milled hemp electrode, enhanced capacity of 300 mA h g À1 is achieved, which is better than [48][49][50] or comparable [51][52][53][54][55] to that of biomass-derived carbon anodes reported in recent years. As observed, the lithium storage capacity depends on whether ball-milling was conducted or not; therefore, for optimizing the condition, the ball-milling time was extended to 3 h. Fig.…”
