“…[17][18][19][20] Mesophase pitch, which consists of parallel-stacked lamellar macromolecules and has a dense structure, has drawn attention as a raw material for high-density isotropic graphite. [21][22][23][24] The specific structural features of mesophase pitch also facilitate its activation into porous carbon of extremely high specific surface area. 11,12,[25][26][27][28][29][30] The pores created in the lamellar carbon structure have been reported to be favorable for high-capacitance double-layer formation.…”

“…The capacitance of the electrodes is further enhanced via Faradaic reactions on the pseudocapacitive materials. 173 In particular, composite electrodes developed through the hybridization of CNTs and polypyrrole have been observed to demonstrate capacitance values higher than either of the parent materials. 173,174 This is due to the presence of the matted structure, allowing a uniform overlay of polypyrrole and three-dimensional charge distribution.…”

The chemistry underlying the storage phenomena in batteries and supercapacitors has been known to mankind for quite some time now. Nonetheless, a holistic apprehension of their rudimentary characteristics throughout their lifetime and beyond is imperative to accentuate their maximum potential. Although numerous reviews have addressed many of the facts individually, a consolidated report on the associated history, challenges, and environmental aspects considering the cutting‐edge advancements in this field is missing. This review gives a comprehensive insight into the two technologies by drawing a detailed comparison between their governing attributes and potential challenges. First, a brief history of batteries and supercapacitors along with their classifications based on materials and corresponding working mechanisms are delineated. Thereafter, some of the inexorable losses restricting the performance of these systems from reaching their theoretical limits are outlined. A picture of the significance of theoretical modeling of batteries and supercapacitors highlighting the associated challenges in the same is drawn. Furthermore, their fates after retirement as well as their scopes in the future based on their current trends are reported in the ensuing sections. Alongside detailed tutorial background of energy storage literature, this review compares different energy storage devices and the latest developments in this field.

“…188,223-227 Similar effects have been found for boron-doped MCMB, graphite, and graphitized coke. [228][229][230][231][232][233][234][235][236] Contrary to boron, nitrogen acts as a donor weakening the bond of lithium to the carbon host structure which causes less positive lithium intercalation potentials in comparison to pure carbon. C x N (7.3 < x < 62) and BC x N (x = 2, 3, 7, 10) compounds have been prepared by CVD of acetylene and ammonia or by pyrolysis of nitrogen-containing organic molecules like acetonitrile, acrylonitrile, or pyridine with BCl 3 between 400°C and 1000°C.…”

“…Improved graphitization at temperatures above 3000°C and the use of graphitization promoters like boron during the graphitization (incorporated by co-pyrolysis of coal tar pitch and boron compounds) as well as surface oxidation allow to increase the maximum obtainable specifi c charge capacity to about 340 mAh g −1 . [224][225][226][227]229,231,235,630,639,640 A further surface modifi cation may establish a favorable surface morphology for a tailored electrolyte compatibility as well as an improved energy density and safety of the lithium-ion cell (cf. Figure 7.20).…”
