Material characteristics and electrochemical performance of lithium-ion capacitor with activated carbon cathode derived from sugarcane bagasse

Abstract

Lithium-Ion Capacitor (LIC), a hybrid energy storage device, is believed to be an ideal option for energy storage device applications due to its properties with high specific energy and high specific power. In this study, LIC’s cathode material is made of activated carbon derived from sugarcane bagasse prepared by the carbonization process at 500OC for 60 minutes and activation process utilizing KOH as an activating agent at varying temperatures and varying ratios of carbon to KOH mass. This paper also compares the material characteristic and electrochemical performance. In this paper, full cells of LIC are fabricated using activated carbon as the cathode material and LTO as the anode material. Sugarcane bagasse activated carbons are characterized by Scanning Electron Microscopy (SEM) and Brunauer Emmett Teller (BET). The electrochemical performance of LIC is obtained from cyclic voltammetry (CV) and charge-discharge (CD). Sugarcane bagasse activated carbon (SBAC) produces a high specific surface area with values from 1095 m2/g to 3554 m2/g. The assembled LIC can produce a maximum specific capacitance of 31.94 F/g, the highest specific energy of 35.49 Wh/kg, and high specific power of 2954.36W/kg.

Electrochemical characteristics of sugarcane bagasse-activated carbon as cathode material of lithium-ion capacitors

“…As shown in Figure 5, SBAC has the dominant element C (carbon) with a percentage of more than 80% and some others O, Si, Cl, and K, which indicates that the method used in this study has succeeded in synthesizing bagasse into activated carbon. The same results were obtained by most of the researchers who used the pyrolysis method with an inert gas (Barruna et al, 2021;Dwiyaniti et al, 2020;Guo et al, 2020;Luo et al, 2019). The dominant carbon content would affect the ion adsorption process in LIC.…”

“…Moreover, 85.7% capacity retention was reported, even after 10 000 cycles. Sugarcane bagasse [ 46 ] was used to produce AC (SBAC) as a cathode material in LIC. The carbon pyrolyzed at 840 °C exhibited a honeycomb‐like morphology with many pores (Figure 3f).…”

Material Characteristics and Electrical Performance of Perovskite Solar Cells with Different Carbon-Based Electrodes Mixed with CuSCN

“…Te frst step in making carbon paste is mixing 1 g of carbon material with 0.1 g of CuSCN [33] and 0.1 g of ethyl cellulose in a ball mill jar and stirring with a ball milling machine for 30 minutes. Te ball milling technique was used because it efectively prepares materials with a large surface area, such as carbon [34,35]. Subsequently, the mixed carbon powder was dissolved in 0.3 ml of C 6 H 5 Cl (chlorobenzene) until it became a carbon paste.…”
