Correlation of energy storage performance of supercapacitor with iso -propanol improved wettability of aqueous electrolyte on activated carbon electrodes of various apparent densities

Fabrication of N-doped and shape-controlled porous monolithic carbons from polyacrylonitrile for supercapacitors

“…In addition, the capacitive behaviors of electrodes were also dependent on the wettability of the inner pores for the electrolyte. 53 Contact angle (CA) measurement was also carried out to study the surface wettability of all electrodes for 1 M H 2 SO 4 aqueous electrolyte, which was used to preliminary evaluate the performance of the electrodes for SCs (Fig. S6, † inset).…”

Synthesis of hierarchically porous MnO2/rice husks derived carbon composite as high-performance electrode material for supercapacitors

“…In contrast to organic electrolytes, mild aqueous electrolytes have merits of high ionic conductivity, nontoxic, safety, non-corrosiveness and convenient assembly in air http://dx.doi.org/10.1016/j.apenergy.2016.06.057 0306-2619/Ó 2016 Elsevier Ltd. All rights reserved. [10,11]. However, the aqueous-based symmetric supercapacitors suffer from narrow potential window due to the limitation of water decomposition.…”

Asymmetric supercapacitor based on activated expanded graphite and pinecone tree activated carbon with excellent stability

“…Electrochemical capacitors (ECs) (ultracapacitors or supercapacitors) [1] have evolved as important electrical energy storage systems for the development of wide range of electrical applications adopted in memory backup devices, hybrid electric vehicles (HEVs), digital and portable electronic devices, etc. [2][3][4]. Their attractiveness is attributed to their high power density, fast charging-discharging mechanism as well as long cycle life and high durability [5].…”
