The formation of the alkyl carbonate-derived solid electrolyte interphase (SEI) enables the use of active materials operating at very cathodic potentials in Li-ion batteries. However, the SEI in semi-solid flow batteries results in a hindered electron transfer between a fluid electrode and the current collector restricting the operating potentials to ca. 0.8 V vs. Li/Li(+) for EC-based electrol...

Single phase sodium/3-alumina solid electrolyte was found to undergo isothermal phase separation in electrochemical ceils, where a large oxygen potential gradient was imposed across the electrolyte and electrodes, not reversible to sodium ions, were short circuited. The experimental conditions and evidence of decomposition are outlined and a thermodynamic explanation for the phenomenon is given...

Single-step ball milling synthesis of a highly conductive glass ceramic solid electrolyte enables low-impedance all-solid-state battery.

The applicability of differential pulse voltammetry (DPV) and adsorptive stripping voltammetry (AdSV) at a non-toxic meniscus-modified silver solid amalgam electrode (m-AgSAE) for the determination of trace amounts of genotoxic substances was demonstrated on the determination of micromolar and submicromolar concentrations of 3-nitrofluoranthene using methanol 0.01 mol L NaOH (9:1) mixture as a ...

In this work, the electrochemical stability and lithium plating/stripping performance of N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (Pyr14TFSI) are reported, by investigating the behavior of Li metal electrodes in symmetrical Li/electrolyte/Li cells. Electrochemical impedance spectroscopy measurements and galvanostatic cycling at different temperatures are performed to ana...

Dye sensitized solar cells (DSSC) are a promising technological alternative to conventional pn-junction solar cells, and therefore attract considerable scientific interest. Different attempts have been made to replace the liquid electrolyte by a solid state hole conducting organic or inorganic medium. This contribution compares electrical properties of three different types of DSSCs. First, we ...

The studies of the electrochemical redox reactions in solvated silica sol–gel glass were reviewed. The methodology of the experiments with emphasis on the direct preparation of the solid electrolyte and the application ultramicroelectrodes was described. Generally, the level of the electrochemical signal is not much below that observed in liquid electrolyte. The current depends on time elapsed ...

Solid-state batteries with inorganic solid electrolytes are expected to be an efficient solution to the issues of current lithium-ion batteries that are originated from their organic-solvent electrolytes. Although solid-state batteries had been suffering from low rate capability due to low ionic conductivities of solid electrolytes, some sulfide solid electrolytes exhibiting high ionic conducti...

Sulfur-containing solid electrolytes are highly attractive to scientists and increasing day by day. Recently, Li7P3S11, Li10GeP2S12, Li11Si2PS12 have been of great interest in literature. The ionic conductivity these can even be reached a value 10-2 S/cm. For this purpose, Li7P3S11 electrolyte is synthesized mechanical alloying method for all-solid-state Lithium Sulfur batteries study. To do th...
