“…[19][20][21] Room temperature ionic liquids (ILs) are promising electrolytes because they possess negligible vapour pressure, low flammability, high ionic conductivity and high electrochemical stability. 22,23 Amongst a variety of ILs, choline-based ILs are considered to be promising, low toxicity ILs for a variety of biomedical applications. [24][25][26] This is mostly due to the fact that choline (more correctly cholinium) is a naturally occurring cation that shows very low toxicity and it can work as a cell signaling agent.…”

With the surge of interest in miniaturized implanted medical devices (IMDs), implantable power sources with small dimensions and biocompatibility are in high demand. Implanted battery/supercapacitor devices are commonly packaged within a case that occupies a large volume, making miniaturization difficult. In this study, we demonstrate a polymer electrolyte-enabled biocompatible magnesium-air battery device with a total thickness of approximately 300 μm. It consists of a biocompatible polypyrrole-para(toluene sulfonic acid) cathode and a bioresorbable magnesium alloy anode. The biocompatible electrolyte used is made of choline nitrate (ionic liquid) embedded in a biopolymer, chitosan. This polymer electrolyte is mechanically robust and offers a high ionic conductivity of 8.9 x 10-3 S cm-1. The assembled battery delivers a maximum volumetric power density of 3.9 W L-1, which is sufficient to drive some types of IMDs, such as cardiac pacemakers or biomonitoring systems. This miniaturized, biocompatible magnesium-air battery may pave the way to a future generation of implantable power sources.

“…From these ionic structures emerge interesting properties such as: low viscosity; low vapor pressure [2]; and good dissolution in many inorganic, organic and polymeric compounds [3]. Huge interest in IL chemistry, and intensification of research on ILs in the last decade is reflected in a growing number of publications referring to IL properties, synthesis and applications [1,[4][5][6] starting with their solvent properties in organic synthesis [7] as well as use in energy storage materials [8], medicine [9], catalysis [10], separation science [11] or crystallography [12] to name only a few. However, the most useful feature of ILs is their tunability of properties possible through chemical modifications of cations or anions and hence adjustment of the intermolecular and interionic interactions [12].…”

Ionic Liquids as Solvents for Rhodium and Platinum Catalysts Used in Hydrosilylation Reaction

et al. 2016

A group of imidazolium and pyridinium based ionic liquids has been synthetized, and their ability to dissolve and activate the catalysts used in hydrosilylation reaction of 1-octane and 1,1,1,3,5,5,5-heptamethyltrisiloxane was investigated. An organometallic catalyst as well as inorganic complexes of platinum and rhodium dissolved in ionic liquids were used, forming liquid solutions not miscible with the substrates or with the products of the reaction. The results show that application of such a simple biphasic catalytic system enables reuse of ionic liquid phase with catalysts in multiple reaction cycles reducing the costs and decreasing the amount of catalyst needed per mole of product.

“…Several authors have already noticed the use of ionic liquids for their use in energy applications such as thermoelectrochemical cells, fuel cells, dye-sensitized solar cells, CO 2 and SO 2 capture and separation, and production of H 2 by water splitting Smiglak et al, 2014). Although most immediate and attractive applications are those involving the electrochemical behavior of ILs, there is an ongoing and emerging research for the use of ILs as fluids for thermal energy storage applications.…”

New technology requirements derived from the exploitation of novel energy resources, and the needs for improvement of the energy efficiency of current power generation systems are pushing the industry towards the search of alternative working fluids. The great challenge for these non-conventional fluids is to provide satisfactory performances and fill the existing lack of media for some innovative energy applications. In this review a number of emerging working fluids for thermal power generation are presented. Also, a special emphasis is devoted to the discussion about new promising fluids, such as nanofluids or ionic liquids, that could be an important breakdown for power generation in the near future.
