Transforming gum wastes into high tap density micron-sized carbon with ultra-stable high-rate Li storage
Original language description
Among various natural wastes, gum wastes pose major issues, as they are unusable and hard to be disposed due to their acidic and sticky nature. Herein, a rational synthetic strategy is employed to transform various kinds of gum wastes into micron-sized carbon, which also exhibit high tap density (1.4-1.7 g cm(-3)) desirable for practical application in lithium-ion batteries (LIBs). Gum karaya (GK) micronsize functional carbon (GKMFC) exhibits the most outstanding electrochemical performance, with a volumetric capacity of 175.4 mAh cm(-3) at a current density of 3000 mA g(-1) for 5000 cycles, and possesses ultra-stable high-rate cyclability (a capacity decay of only 0.001881% per cycle). Additional electrochemical analyses reveal that GKMFC exhibits stable structural integrity as well as minimal cell resistance even after cycling, showing its practical application as viable electrode for LIBs. This work sheds light on utilizing high tap density carbon from gum wastes for LIBs, which can also be applicable to other natural wastes and carbon. (C) 2020 Published by Elsevier Ltd.
