“…a high surface carbon electrode and electrolyte. The electrolyte may be aqueous [18], organic (where usually acetonitrile (AN) or propylene carbonate (PC) are applied as solvents [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]), a solvent-free ionic liquid [34][35][36][37] or polymer gel electrolyte [38][39][40][41][42]. Inspection of original papers and review articles [43][44][45][46] suggests that most of EDLC research is devoted to the preparation of new carbons and studies of their performance as electrode materials.…”

“…In an earlier publication, we had reported excellent properties of SBP BF 4 salt (1,1 0 -spirobipyrrolidinium (SBP, 5-azoniaspiro [4.4]nonane)), and its oxygenated derivatives for electric double layer capacitor applications [1,2]. Their superior chemical and electrochemical robustness, high solubility range, wide voltage window, and conductivity make them especially suitable for electrical energy storage applications, including supercapacitors [3][4][5][6][7][8].…”

“…Their superior chemical and electrochemical robustness, high solubility range, wide voltage window, and conductivity make them especially suitable for electrical energy storage applications, including supercapacitors [3][4][5][6][7][8]. We have been investigating SBP-based oxygen-containing spiroammonium salts for preparation of room temperature ionic liquids (RTILs) without sacrificing other preferable properties [1,2]. Introduction of oxygen atoms to aliphatic ammonium cations frequently lead to formation of low melting point and less viscous salts [9][10][11][12][13] is widely reported.…”

“…The presence of organic solvents yields better conductivity than neat ILs. As this chapter is devoted to EDLCs based on solvent-free ILs, for supercapacitors with mixed IL/organic solvent electrolytes see [36][37][38][39][40][41].…”

IntroductionEDLCs are supercapacitors featuring two high-surface-area porous carbon electrodes and an electrolyte are electrochemical energy storage systems that are electrostatically charged by separation of charge at both the electrode/electrolyte interfaces. They store charge in the double layers without chemical reactions and physical changes in the electrode material bulk and, hence, the charge/discharge process is highly reversible and fast. This implies the advantage of high power and long cycle life (at least 300 000 cycles). The maximum energy (E max ) of supercapacitors, delivered between V max and V max /2, is calculated according to Eq. (9.1),where C SC is the supercapacitor capacitance expressed in F and V max the maximum cell voltage in V. The maximum power (P max ) is given by Eq. (9.2),where ESR is the equivalent series resistance in [1,2]. Since the first patents on supercapacitors appeared, EDLCs have been largely used in consumer electronic products and in uninterruptible power supply (UPS) systems. Worldwide demand for ''clean'' energy in the past few years has fostered the interest in supercapacitors for applications in grid-connected renewable energy plants, so as to enhance grid reliability by buffering the small and rapid (≤ minute) fluctuations, and in sustainable transportation. EDLCs are also being increasingly exploited in hybrid diesel-electric seaport cranes, where they enable size reduction of the diesel engine and capture energy otherwise wasted as heat in the down movement of heavy containers [2][3][4].In transportation, supercapacitors can store energy from regenerative braking and provide and/or assist power train in heavy electric vehicles (EVs) and hybridelectric vehicles (HEVs) of limited driving range with frequent stop-and-go, such
