“…As the area of the plate increases and the distance between the plates decreases, the capacitance of the capacitors increases. Specific capacitance of super-capacitors is heavily influenced by carbon electrodes with a significant surface space available to electrolyte ions, porous carbon materials such as activated carbon [132], carbide-derived carbons [133,134], arranged meso-porous carbons [135,136], carbon aerogels and carbon nanotubes have been investigated as large-surface electrodes [137]. Graphene-based materials are desirable because of their elevated theoretical volume ratio (2630 m 2 g −1 and electrical conductivity) [138] as electrode materials for super-capacitors.…”

Two-dimensional (2D) graphene and its outstanding properties such as, enormous conductivities, mechanical strength, optical and electrical properties brought it one of the most studied materials for the production of energy using renewable resources. The composites of graphene with the same morphological materials such as layered transition metal oxides will be the most aspiring combination to boost their conducting, optoelectronic and mechanical properties. Furthermore, the transition metal chalcogenides materials attracted significant attention due to their atomically thin layers and enormous optical, conducting and electrical properties. The layered materials offer mostly atomically thin 2D plane to the charge carrier with superior conducting properties. The thickness at atomic level, band gap, spin orbit coupling electronic and optoelectronics properties of transition metal dichalcogenides makes them one of the promising entities in energy harvesting technologies. The review suggests some strategies to improve the transition metals-composites stability conducting properties to be tailored in various applications.

“…Over the years, many carbon based materials including activated carbon, mesoporous carbon, carbon aerogels, carbon nano fibers, carbon spheres, carbon nanotubes, graphene, carbide derived carbons etc have been studied as electrode materials for LIBs & SCs applications . However, inappropriate pore size/shape and tedious synthesis process of these carbon materials impedes their practical application . In recent years, ordered mesoporous materials are quite fascinating and attractive for energy storage because of their excellent textural characteristics such as high specific surface area, pore volume, tunable pore size, and also provide mesochannels for rapid and easy diffusion of electrolyte ion species at high rates …”

“…have studied the supercapacitive properties of mesoporous carbon materials with various pore sizes that are prepared from SBA‐15 silica template and concluded that the size of the pores highly influences the specific capacitance of the material . Also extensive efforts have been made to study the effect of pore structure of two dimensional (CMK‐3) and three dimensional (CMK‐8) mesoporous carbons on the electrochemical properties of supercapacitor and Li‐ion battery applications and concluded that the unique three dimensional cubic mesostructure of CMK‐8 helps in rapid mass transport and charge transfer better than 2D hexagonal CMK‐3, which helps in delivering better electrochemical performance for CMK‐8. However, to the best of our knowledge, the study on pore size engineering/tuning of three dimensional ordered mesoporous carbon (CMK‐8) for SC and LIB applications has been rarely reported.…”

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.

“…Материал типа СМК-3 привлекает внимание в связи с большой площадью поверхности (около 1000 см 3 /г), упорядоченной мезопористой структурой, которая способствует доступности поверхности при формировании двойного электрического слоя (ДЭС), скорости внутрипорового ионного переноса и высокой электропроводности [3]. CMK-3 демонстрирует бóльшую удельную емкость (около 80 Ф/г), чем CMK-8 -68 Ф/г [12]. Авторы утверждают, что удельная емкость зависит от площади мезопористой поверхности (S meso ), а не от общей удельной площади BET (S BET ).…”

Mesostructured carbon material CMK-3 for electrodes of electrochemical capacitors was obtained by the method of template synthesis. In order to increase the capacitance characteristics, impregnation of metal ions (Co, Ni, and Cu) into the structure of mesoporous carbon CMK-3 was carried out. The structure of the obtained materials was studied by X-ray diffraction and gas adsorption. The study by TEM showed that highly dispersed, nanosized particles are metal oxides Co, Ni and Cu with the size of 30-50 nm. The particles are uniformly distributed inside the carbon material. Electrochemical characteristics were studied in aqueous electrolytes (1M KCl and 1M KOH). It has been established that the impregnation of metal ions increases in the specific capacity of the mesoporous carbon material by about 30 % (from 110 to 156 F/g) in KOH
