Ionic-liquid materials for the electrochemical challenges of the future.

TLDR
The goal in this review is to survey the recent key developments and issues within ionic-liquid research in these areas, and to generate interest in the wider community and encourage others to make use of ionic liquids in tackling scientific challenges.
Abstract
Ionic liquids are room-temperature molten salts, composed mostly of organic ions that may undergo almost unlimited structural variations. This review covers the newest aspects of ionic liquids in applications where their ion conductivity is exploited; as electrochemical solvents for metal/semiconductor electrodeposition, and as batteries and fuel cells where conventional media, organic solvents (in batteries) or water (in polymer-electrolyte-membrane fuel cells), fail. Biology and biomimetic processes in ionic liquids are also discussed. In these decidedly different materials, some enzymes show activity that is not exhibited in more traditional systems, creating huge potential for bioinspired catalysis and biofuel cells. Our goal in this review is to survey the recent key developments and issues within ionic-liquid research in these areas. As well as informing materials scientists, we hope to generate interest in the wider community and encourage others to make use of ionic liquids in tackling scientific challenges.

High Rates of Oxygen Reduction over a Vapor

Abstract: The air electrode, which reduces oxygen (O2), is a critical component in energy generation and storage applications such as fuel cells and metal/air batteries. The highest current densities are achieved with platinum (Pt), but in addition to its cost and scarcity, Pt particles in composite electrodes tend to be inactivated by contact with carbon monoxide (CO) or by agglomeration. We describe an air electrode based on a porous material coated with poly(3,4-ethylenedioxythiophene) (PEDOT), which acts as an O2 reduction catalyst. Continuous operation for 1500 hours was demonstrated without material degradation or deterioration in performance. O2 conversion rates were comparable with those of Pt-catalyzed electrodes of the same geometry, and the electrode was not sensitive to CO. Operation was demonstrated as an air electrode and as a dissolved O2 electrode in aqueous solution.

Ionic liquid salt-induced inactivation and unfolding of cellulase from Trichoderma reesei

TL;DR: Experiments have indicated that [bmim]Cl, and several other ILs, as well as dimethylacetamide–LiCl (a well-known solvent system for cellulose), inactivate cellulase under these conditions.

Preparation of room temperature ionic liquids based on aliphatic onium cations and asymmetric amide anions and their electrochemical properties as a lithium battery electrolyte

TL;DR: In this article, the physical and electrochemical properties of room temperature ionic liquids (RTILs) based on asymmetric amide anions (TSAC: 2,2,2-trifluoro-N -(triffluoromethylsulfonyl)acetamide, C1C2: N -(tricyclic polysilicon)pentafluoroethylsulfonamide) and aliphatic onium cations, such as ammonium, phosphonium and sulfonium, were reported.

Ionic liquids as stable solvents for ionic polymer transducers

TL;DR: In this article, the use of highly stable ionic liquids to replace water is explored, which is due to the chemical breakdown of the water at relatively low operating voltages and the loss of water to evaporation when these devices are operated in air, causing a corresponding loss of performance.

PEO-Based Polymer Electrolytes with Ionic Liquids and Their Use in Lithium Metal-Polymer Electrolyte Batteries

TL;DR: In this paper, the room temperature ionic liquid (RTIL) N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR 1 3 TFSI) was added to LiTFSI polymer electrolytes and the use of these electrolytes insolid-state Li/V 2 O 5 batteries has been investigated.
