“…So, the current research is focused on developing high performing anode materials in order to prevail over the limitations from using graphite. Carbon materials in various forms such as mesoporous carbons, CNTs, carbon nanofibers, graphene, carbon spheres have been explored over the years and these carbon materials usually have high theoretical specific capacity in comparison to graphite due to storage of more number of lithium ions in the high surface area materials. Nevertheless, the synthesis of porous carbons from bio mass waste is a convenient and economic process, since the raw material is naturally available and does not require any tedious procedures for material processing and engineering.…”

Summary Graphitic porous carbon sheets (GPCS), which were synthesized at a low temperature of 900°C by KOH chemical activation technique, possess a specific surface area of 1246 m2 g‐1 with high pore volume. The size of the pores varied in micro‐mesopore regions and exhibited three‐dimensional sheet‐like morphology composed of multilayered graphene sheets with an inter planar distance of 0.360 nm. The GPCS material was tested as anode for Li‐ion battery (LIB) application in half cell mode (vs Li+/Li). The fabricated GPCS electrode shows excellent electrochemical properties in comparison with commercial graphite such as a high discharge specific capacity of 1022 mA h g‐1 after 10 cycles at 100 mA g‐1 and excellent specific capacity retention of 170 mA h g‐1 at a very high current rate of 8000 mA g‐1 and also retains a high capacity of 541 mA h g‐1 after 250 cycles at 500 mA g‐1, which suggests that GPCS material can be a promising electrode for LIB application. A brief comparison with commercial graphite and various carbonaceous materials from literature demonstrated that the GPCS electrode was potential material for high rate LIBs.

The design and development of bio‐renewable and sustainable carbon‐carbon based supercapacitor electrodes provide high volumetric energy density and high durability even at higher potential window are one of the major technological challenges. The present study demonstrates the conversion of wheat flour as bio‐renewable and sustainable resource into hierarchical high surface area bi‐model porous carbon nanosheets (1620 m2 g−1) as high performance supercapacitor electrode. Bi‐model porous carbon can provide the high electrochemical performance because it has optimum textural characteristic. The benefit from simultaneous achievement of extended voltage window of 3.2 V and high volumetric capacitance of 86 F cm−3 with high electrode density of 0.76 g cm−3, the supercapacitor cell can provide higher volumetric energy density of 30.46 Wh L−1. Particularly, supercapacitor cell shows exceptional rate capability at commercial level active mass loading (10 mg cm−2) and high durability at 3.2 V upon 15,000 charge‐discharge cycles with 95 % of capacitance retention. The integrated power electronic booster and the concept of recovery of the stored energy from the supercapacitor are explained by a simulation as well as experimental study for the first time. This work inspires new insights to develop a sustainable high volumetric supercapacitor for portable and wearable device applications.

“…Figure 8A shows the chargedischarge curves of mesoporous carbon for the 1 st , 2 nd , 50 th , 100 th , 200 th and 300 th cycles at 0.5 A/g current density in the voltage window of 0.01-3 V. It shows a high irreversible discharge capacity of 1546 mA h/g in the 1 st cycle with a high initial coulombic efficiency of 65.3%, which is higher than some of the porous carbon materials reported for state of the art LIBs as seen in Table 3. [17,[45][46][47][48][49][50][51][52] Moreover, a large irreversible capacity in the 1 st cycle can be ascribed to the solid electrolyte interphase (SEI) layer formation, caused due to the reaction of lithium with electrolyte, decomposition of electrolyte and also due to irreversible lithium insertion into special positions in the vicinity of residual H atoms in the carbon material. [49,50,53] Nevertheless, in the 2 nd cycle, a significant steady reversible capacity of 820 mA h/g with 98.5% coulombic efficiency was obtained.…”

“…After cycling at various current densities, when the current density was switched back to 0.1 A/g, the specific capacity of mesoporous carbon can still be recovered to 1050 mA h/g, indicating highly stable cycling performance and good reversibility. As seen in Table 3, the rate performance of the mesoporous carbon is superior to some of the carbon materials reported in literature such as carbon nano particles, [51] graphene, [47] carbon spheres, [48] hierarchical porous carbon, [49] 2D mesoporous carbon CMK-3, [17] MOF derived nitrogen doped carbon, [50] 3D microstructure carbon [45] and slightly inferior to nitrogen doped graphitic carbon spheres [52] and nitrogen doped porous carbon nanofiber materials. [46] The superior rate capability can be attributed to the unique 3D cubic mesostrucuture of the ordered carbon which would facilitate rapid electrolyte ion transport throughout the mesoporous channels without any pore blockage and also reduces the transport path for electrolyte diffusion which improves the rate performance characteristics of the electrode material.…”

Pore Size‐Engineered Three‐Dimensional Ordered Mesoporous Carbons with Improved Electrochemical Performance for Supercapacitor and Lithium‐ion Battery Applications

Three-dimensional ordered mesoporous carbons (OMCs) are desirable for high performing energy storage devices because they provide a continuous electron pathway to ensure good electrical contact and also facilitate electrolyte ion transport by reducing diffusion lengths during charge-discharge process. Here, we report the synthesis of three dimensional mesoporous carbon (CMK-8) using KIT-6 and sucrose as silica template and carbon source, respectively. Initially, KIT-6, synthesized at different hydrothermal temperature (100, 130 and 150°C) is used as silica template to prepare OMCs with different pore diameter. The resulting OMCs were extensively characterized by SAXS, FE SEM, HR-TEM, BET and Raman techniques. The SAXS pattern shows distinct reflections at low 2θ range corresponds to ordered mesoporous structure of cubic Ia3d space group. The OMC possesses a specific surface area of 1017 m 2 /g with a mean pore size of 4.1 nm and large pore volume of 1.14 cm 3 g À 1 . As electrode material for supercapacitor application, the resulting mesoporous carbon delivers a high capacitance of 252 F/g @ 0.5 A/g and shows good rate performance (75% retention in capacitance at high current rates) and outstanding cyclic stability (91% retention after 30,000 cycles). Further, as anode for Li-ion battery application, it also exhibits promising specific capacity (856 mAh/g) with good cyclic and rate capability. The excellent electrochemical properties of the mesoporous carbon material are attributed to its three dimensional porous structure and high surface area with interconnected mesopores that provides rapid ion and electron transport during electrochemical process.
