DOI: 10.1002/aenm.201600922 considering the overpotential during charge process. Recently, Yamada et al. reported that LiNi0.5Mn1.5O4 can only reversibly provide capacity of ≈75 mA h g−1 in the more concentrated hydrate melt electrolytes (≈30 mol kg−1), which is 50% of theoretical capacity.[14] The oxygen evolution side reaction also largely significantly reduce the coulombic efficiency. In add...

Compared to aqueous electrolytes, fundamental understanding of the chemical and electrochemical processes occurring in non-aqueous electrolytes is far less developed. This no different for Li-ion battery (LiB) where many questions regarding solid-electrolyte interphase (SEI) on anode side remain unanswered, including its composition, mechanism formation, impact LiB performance. Here, we present...

A hydrated eutectic electrolyte with 3D percolating hydrogen bond network is designed for high-performance aqueous Mg-ion batteries.

In this work, reactive absorption of gases in aqueous electrolyte solutions has been investigated resulting in the development of a procedure in order to calculate the concentrations of ionic and molecular species in the liquid phase. Two duplicate experiments were conducted to investigate simultaneous reactive absorption of ammonia and carbon dioxide in partially carbonated ammonia solutio...

Intermolecular forces tend to organize water molecules into a tetrahedral lattice, conferring "crystalline" properties on the liquid. The simple ions, such as Na+, K+, and Cl-, have dinmensions which are of the same order as the water nmolecule. Therefore, in aqueous solution, ions can substitute for water molecules in the water lattice. However, because the force between ion and water molecule...

Aqueous ammonium ion battery is a promising sustainable energy storage system. However, the side reactions originating from electrolytes (the water decomposition and host material dissolution) preclude its practical applications. Unlike metal-based aqueous batteries, idea of “ultrahigh concentrated electrolyte” not feasible due to strong hydrolysis ions. Therefore, we propose an effective strat...

copolymerization of aniline and 2-anilinoethanol was carried out by electrochemical and chemical polymerization. homo and copolymer thin films were synthesized electrochemically, under cyclic voltammetric conditions in aqueous solutions of sulfuric acid as electrolyte at room temperature. the films were deposited on the surface of working electrode [glassy carbon ()gc)(] versus ag/agcl electrod...

Capillary electrophoretic methods are traditionally used for the separation of charged species. A neutral compound is often used as a background (electroosmotic flow) marker. The assumption made is that no significant interaction occurs between neutral compounds and the various ions moving through the capillary. This is true for aqueous environments because the very polar nature of water overpo...

With the aid of density functional calculations, it was revealed that neuraminidase (NA) inhibitors (Scheme 1) exist exclusively in the neutral form. However, the docking and molecular dynamics simulations indicated that the zwitterionic, rather than neutral, isomers are the active form in NA-receptors. The neutral and zwitterionic isomers of BA (Compound 7 in Scheme 1) are quite different in s...
