By means of in situ IR spectroscopy we investigate the effect of dissolved alkali cations on the electro-oxidation of ethylene glycol on platinum in alkaline media. The results revealed that the increase in the oxidation currents (Li(+) < Na(+) < K(+)) is reflected in the increase in the ratio between carbonate and oxalate produced.

The interaction of the Li-ion battery solvent ethylene carbonate (EC) with Cu(111) was investigated by scanning tunnelling microscopy (STM) and variable temperature X-ray photoelectron spectroscopy (XPS) under ultrahigh vacuum (UHV) conditions. Between 80 and 420 K, the decomposition of EC occurs along with distinct structural and chemical changes of the adlayer.

Monodispersed particles of amorphous calcium carbonate (ACC) 90 to 200 nm in diameter are accessible at room temperature in ethylene glycol and water using a vortex fluidic device (VFD). The ACC material is stable for at least two weeks under ambient conditions.

Ethylene carbonate is a rather uncommon solvent in chemistry, but it can be used as low-viscosity, polar, aprotic solvent. Its most interesting feature the melting point above room temperature, which allows for crystallization of ethylene carbonate-based catalyst phase from reaction solution. The dynamic behavior such systems was investigated depth this work. and hydroformylation product nonana...

The ethylene carbonate additive regulates Zn anode behavior, enhancing the capacity retention of full cell (N/P = 1.3) from 51.1% to 80.5%.

A multifunctional coupler with an ethylene carbonate- and a thiolactone ring was synthesized. As proof of principle the coupler was reacted with four low-molecular weight building blocks to form a multifunctional molecule. The reactivity/selectivity of the coupler towards amines, acrylates and acyl halides was evaluated.

LaNi4.4Sn0.25 and graphite powder disk electrodes sandwiched between two nickel screens were used as working electrodes in 6.0 M KOH and in 1.0 M LiPF6 in propylene carbonate-ethylene carbonate-dimethyl carbonate ~1:1:3! solution, respectively. Different electrochemical impedance spectroscopy protocols were used for analysis of the kinetics of insertion and extraction of hydrogen and lithium in...

Electrolytic solutions of lithium-ion batteries can be modified with additives to improve their stability and safety. Electroactive molecules can be used as such additives to act as an electron (redox) shuttle between the two electrodes to prevent overcharging. The electroactive ionic liquid, 1-ferrocenylmethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (TFSI), was synthesised and i...

The increase in the concentration of electrolytes for secondary batteries has significant advantages terms physicochemical and electrochemical performance. This study aims to explore a highly concentrated electrolyte Na-ion using ternary salt system. eutectic composition Na[N(SO2F)2]–Na[N(SO2F)(SO2CF3)]–Na[SO3CF3] molten system increases solubility into an organic solvent, enabling use batterie...

A small difference caused by a single methyl group between EC and PC could cause large in lithium alkyl carbonates.
