A viable Li/O2 battery will require the development of stable electrolytes that do not continuously decompose during cell operation. Recent experiments suggest that reactions occurring at the interface between the liquid electrolyte and the solid lithium peroxide (Li2O2) discharge phase are a major contributor to these instabilities. To clarify the mechanisms associated with these reactions, a ...

Polymer electrolyte membrane fuel cells (PEMFCs) are prone to dehydration and liquid water flooding, negatively impacting their performance lifetime. Therefore, PEMFCs require appropriate management, which makes accurate modeling indispensable. Unfortunately, available control-oriented models only replicate individual water-related aspects or use oversimplistic approximations. This paper resolv...

Two dynamic models have been built for air-breathing and conventional polymer electrolyte fuel cells (PEFCs) in order to comparatively investigate the impacts of some key parameters on transient response load alterations steady-state performance each cell type. It was found that with alterations, PEFC is significantly slower than this due heat transfer coefficients associated natural convection...

Solid–liquid equilibria in mixed electrolyte aqueous solution have been investigated using available thermodynamic data for solids and for aqueous electrolyte solutions. The mean spherical approximation (MSA) modified by Lu et al. [Fluid Phase Equilib. 85 (1993) 81] is used to calculate the mean ionic activity coefficients in mixed electrolyte solutions at saturation conditions. Solid–liquid eq...

Nowadays it is extremely urgent to seek high performance solid polymer electrolyte that possesses both interfacial stability toward lithium/graphitic anodes and high voltage cathodes for high energy density solid state batteries. Inspired by the positive interfacial effect of vinylene carbonate additive on solid electrolyte interface, a novel poly (vinylene carbonate) based solid polymer electr...

ten solanum tuberosum cultivars and accessions from 11 wild solanum species were evaluated for their tolerance to salt (200 mm nacl or 100 mm na2so4), drought (35% peg), cold (-4ºc) and heat (37ºc). evaluation was based on electrolyte leakage from de-tached leaves of in vitro plantlets. testing involved a rinsing treatment with three changes of distilled water to remove electrolytes from leaf a...

Pure water does not conduct electricity, but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound, which produces the ions as it dissolves, is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly, a weak electrolyte dis...
