“…Ionic liquids have attracted considerable attention as electrolyte components in various electrochemical systems such as supercapacitors, [1][2][3] lithium ion batteries, [4,5] electrochromic devices [6] and dye sensitized solar cells (DSSCs) [7,8] because of their favourable properties such as high thermal and electrochemical stability, low volatility and high conductivity. [9][10][11] The most attractive property of ILs is the possibility of fine tuning of their physical and electrochemical properties by changing the chemical composition. ILs have been widely studied as electrolytes for DSSC applications and solar to electric power-conversion efficiency of 10 % was obtained for an ionic liquid based DSSC.…”

Imidazolium-based ionic liquids (ILs) with allyl and ether side chains were synthesized and characterized. Comprehensive structural and photoelectrochemical characterizations were performed, transport properties of ILs were also examined as electrolyte components in dye sensitized solar cells (DSSCs). The properties of synthesized materials and DSSC performances were compared with 1-propyl-3methyl imidazolium iodide (PMII) and 1-allyl-3-ethyl imidazolium iodide (AEII) as reference ILs. Ionic conductivities, diffusion coefficients and charge transfer resistances of synthesized ionic liquids were investigated on DSSCs by Electrochemical Impedance Spectroscopy (EIS). The diffusion coefficient values of triiodide ions in different ionic liquid-based electrolytes were measured by the means of diffusion limited current density method and found to be 1.75 × 10 À 7 cm 2 s À 1 and 2.05 × 10 À 7 cm 2 s À 1 with corresponding photocurrent densities of 10.38 mAcm À 2 and 12.13 mAcm À 2 for the reference AEII and PMII based electrolytes, respectively. However, for the electrolytes of 1-(2-methoxyethyl)-3allyl imidazolium iodide and 1-allyl-3-methyl imidazolium iodide ionic liquids, these values were found to be 0.86 × 10 À 7 cm 2 s À 1 and 0.57 × 10 À 7 cm 2 s À 1 with photocurrent densities of 9.53 mAcm À 2 and 8.98 mAcm À 2 , respectively. Allyl and ether substituted imidazolium ILs exhibited promising results as potential alternative electrolyte materials for DSSCs.

“…Ionic liquids are formed by an organic cation and an organic or inorganic anion presenting as molten salts, many of which are liquid at room temperature. 16 They possess several excellent properties including negligibly low vapor pressures, 17 electrochemical stability, chemical stability, 18 thermal stability, high ionic conductivity, 19 low flammability, 20 and excellent lubricity, 21 which promotes the application of them in various energy fields such as fuel cells, 22 solar cells, 23 batteries, 24 and energy storage. 25 As the most promising compression solution, in the ionic liquid compressor, the solid piston of the reciprocating compressor is substituted by the ionic liquid piston and driven by the hydraulic system.…”

Summary The ionic liquid compressor is regarded as the most promising compression technology for the hydrogen refuelling station due to the combined application of ionic liquid and the hydraulic driving system. However, the design, mathematical and experimental investigations of the ionic compressor are still absent from the open literature. This paper proposed a new structure design and the design methodology of the ionic liquid compressor. The mathematical modelling considering the valve dynamics was provided for simulating the thermodynamic process, which was verified by the experimental data. The results showed that the delayed closing of the discharge valve would take place due to a high or low stiffness of the valve. The increase in the stiffness alleviated the rebound issue of the suction valve. An increase in the stroke to diameter ratio could solve the rebound issue of the discharge valve. A low or high trajectory coefficient would cause an intense rebound during the closing procedure of the discharge valve. The designed results of the main parameters of the compressor based on the simulation were the suction valve stiffness of 100 N/m, the discharge valve stiffness of 500 N/m, the stroke to diameter ratio of 1.0, and the trajectory coefficient of 0.125 under the given design condition.
