Oxygen Reduction Reactions in Ionic Liquids and the Formulation of a General ORR Mechanism for Li–Air Batteries

TL;DR: In this article, a strong correlation was found between ORR products and the ionic charge density, including those of ionic liquids, and the observed trend was explained in terms of the Lewis acidity of the cation present in the electrolyte using an acidity scale created from 13C NMR chemical shifts and spin-lattice relaxation (T1) times of 13C═O in solutions of these charged ions in propylene carbonate (PC).
Journal ArticleDOI

Mitigation of Layered to Spinel Conversion of a Li-Rich Layered Metal Oxide Cathode Material for Li-Ion Batteries

TL;DR: In this paper, Li-rich layered NMC composite cathode material of the composition 0.3Li2MnO30.33O2, synthesized as 200-300 nm size particles, was compared to its counterpart without Na.
Journal ArticleDOI

Unifying the Hydrogen Evolution and Oxidation Reactions Kinetics in Base by Identifying the Catalytic Roles of Hydroxyl-Water-Cation Adducts.

TL;DR: It is shown that the alkaline HER/HOR kinetics can be unified by the catalytic roles of the adsorbed hydroxyl (OHad)-water-alkali metal cation (AM+) adducts, on the basis of the observations that enriching the OHad abundance via surface Ni benefits the HER/hOR; increasing the AM+ concentration only promotes the HER, while varying the identity of AM+ affects both HER and HOR.
Journal ArticleDOI

Preparation and characterization of poly(vinyl sulfone)- and poly(vinylidene fluoride)-based electrolytes

TL;DR: In this paper, a novel group of polymer electrolytes based on poly(vinyl sulfone) (PVS) and polyvinylidene fluoride (PVdF) polymers, plasticized with highly conductive solutions of LiClO4, LiN(CF3SO2)2 or LiAsF6, were prepared via in situ photopolymerization and solution casting, respectively.

TL;DR: In this article, a rechargeable Li/O{sub 2} battery is reported, which consists of a conductive organic polymer electrolyte membrane sandwiched by a thin Li metal foil anode, and a thin carbon composite electrode on which oxygen, the electroactive cathode material, accessed from the environment, is reduced during discharge to generate electric power.
