“…Previous research explained that carbon from plants has the potential to be used as a supercapacitor that ranging from banana peels (Nazhipkyzy, Yeleuov, et al, 2022), grass (She et al, 2018), soybeans (Chung et al, 2020), corn stalks (Kigozi et al, 2020), coconut shell (Lee et al, 2021), and water spinach (Lin et al, 2022). Water spinach (Ipomoea Aquatica) is an aquatic plant that can be found in Southeast China, India, and Southeast Asia that can easily grow in water areas such as rivers, rice fields, and swamps by forming large colonies (Yu et al, 2018;Ma et al, 2019;Abdul Aziz et al, 2020).…”

Currently, lithium-ion batteries still use electrodes from graphite, which is a natural resource for non-metallic minerals. As a sustainable plan, research on the manufacture of lithium-ion batteries based on biomass electrodes has prospects for commercial development. In this study, carbon stems of water spinach (Ipomoea Aquatica) were used as electrodes on the battery. Water spinach is processed into nanocarbon by hydrothermal method and pyrolysis. The size of the nanocarbon particles from water spinach in this study was 200 mesh resulting from the grinding method. The type of battery made is a bag battery with a size of 8×12 cm by performing variable optimization by using a concentration of 50% LiCl/Li 2 SO 4 electrolytes media, Polyurethane/Polyacrylate binder, and Triethylamine/ Non-emulsifier. The highest power and energy values are generated from carbon based lithium-ion batteries from water spinach with LiCl electrolyte media, Polyurethane binder, and Triethylamine emulsion which is 5.404 W and 4.511 W•h.

“…Additionally, biomass as an activated carbon precursor is a renewable, sustainable, and eco-friendly resource. 6,7 So far, activated carbons from various biomass sources such as rapeseed meal, 8 water spinach, 9 cotton stalk, 10 cherry flowers, 11 mango seeds, 12 spruce bark, watermelon rind, 13 tree bark, 14 and many more have been explored and investigated for supercapacitor electrodes. Corn derivatives are the choice of biomass precursors in this work, as they are inexpensive and a readily available agricultural resource.…”

Porous activated carbons from four types of corn derivatives (husk, fiber, grain, and cob) are compared for the first time regarding their structural, morphological, and electrochemical characteristics for application as electrode materials in flexible supercapacitors. Benefiting from its hierarchical porous structure, appropriate amount of N and O functional groups, large specific surface area (1804 m 2 g –1 ), and high degree of graphitization, the activated carbon from corn grains displayed the best electrochemical performance as an electrode material for supercapacitor applications; when tested in a three-electrode configuration, it had a high specific capacitance (411 F g –1 at 1.0 A g –1 ) and an excellent rate capacity (85.7% capacitance retention at 30 A g –1 ) in an aqueous 6 M KOH electrolyte. The high specific surface area and high degree of graphitization of the activated carbon from corn grains (AC grain) played crucial roles in its excellent energy storage performance. Most importantly, the flexible supercapacitor that was assembled with slot-die coated AC grain electrodes and a hydroxyethyl cellulose (HEC)/KOH biopolymer electrolyte delivered an outstanding electrochemical performance with an energy density of 31.1 Wh kg –1 at 215 W kg –1 and ultrahigh cyclic stability (91.3% capacitance retention after 10 000 cycles at a current density of 5 A g –1 ). Also, the assembled flexible supercapacitor maintained an energy density of 20.03 Wh kg –1 even under a high power density of 28.01 kW kg –1 . These findings conclude that the porous carbon material obtained from corn grains has enormous potential as a high-performance electrode material for supercapacitors.
