“…Composites of conducting polymers with carbon nanotubes are promising electrode materials as supercapacitors because of their good conductivity, high surface area, and excellent ability to store energy [7,[108][109][110][111][112][113][114][115][116][117]. The composites combine the large pseudocapacitance of conducting polymers with the fast charging/discharging double-layer capacitance and excellent mechanical properties of carbon nanotubes [118].…”

This review is focused on the theoretical and practical aspects of electrochemical c a p a c i t o r sb a s e do nc a r b o nn a n o t u b e s .I np articular, recent improvements in the capacitance properties of the systems are discussed. In the first part, the charge storage mechanisms of the electrochemical capacitors are briefly described. The next part of the review is devoted to the capacitance properties of pristine single-and multi-walled carbon nanotubes. The major portion of the review is focused on the capacitance properties of modified carbon nanotubes. The electrochemical properties of nanotubes with boron, nitrogen, and other atoms incorporated into the carbon network structure as well as nanotubes modified with different functional groups are discussed. Special attention is paid to the composites of carbon nanotubes and conducting polymers, transition metal oxides, carbon nanostructures, and carbon gels. In all cases, the influences of different parameters such as porosity, structure of the electroactive layer, conductivity of the layer, nature of the heteroatoms, solvent and supporting electrolyte on the capacitance performance of hybrid materials are discussed. Finally, the capacitance properties of different systems containing carbon nanotubes are compared and summarized.

Impact of the Acid Treatment on Lignocellulosic Biomass Hard Carbon for Sodium‐Ion Battery Anodes

The investigation of phosphoric acid treatment on the performance of hard carbon from a typical lignocellulosic biomass waste (peanut shell) is herein reported. A strong correlation is discovered between the treatment time and the structural properties and electrochemical performance in sodium-ion batteries. Indeed, a prolonged acid treatment enables the use of lower temperatures, that is, lower energy consumption, for the carbonization step as well as improved high-rate performance (122 mAh g at 10 C).

“…Carbon-based supercapacitors (SCs), also known as electric double layer capacitors, are promising energy storage devices due to their high power density, high rate preference, and ultra-long cycle life. [1][2][3][4][5]33,43] However, compared with the batteries, the relatively low energy density of SCs limits their large-scale application. Therefore, great efforts have been devoted to increase the energy density of SCs.…”

Supercapacitors (SCs) based on porous carbon exhibit high power delivery/uptake and ultra‐long cycle life but are limited by their low energy density. A critical problem is that their theoretical operating potential windows (OPWs) cannot be fully utilized, owing to the unreasonable potential ranges of electrodes, leading to significantly decreased energy density. Here, the electrode potential ranges of SCs based on activated carbon electrodes and ionic liquid electrolytes were successfully optimized by mass‐balancing and pre‐charging strategies. Consequently, the OPWs of the two resultant SCs were extended to the theoretical value of 4.0 V, and superior energy densities of 112.33 Wh kg−1 and 132.56 Wh kg−1 were obtained, respectively. Moreover, the features of these two strategies were compared. Mass‐balancing is easy to implement, but the corresponding SC shows a relatively low energy density because of the different mass loadings of two electrodes. Pre‐charging enables SC to achieve higher energy density, but it is difficult to control due to self‐discharge.
