Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are critical to renewable energy conversion and storage technologies. Heteroatom-doped carbon nanomaterials have been reported to be efficient metal-free electrocatalysts for ORR in fuel cells for energy conversion, as well as ORR and OER in metal-air batteries for energy storage. We reported that metal-free three-dimensional (...
this study investigates the vertical replacement of salts, variability of electrical conductivity (ec) and soil acidity (ph) due to direct electrical current. a plexiglas cylinder 100 cm in depth with a 14 cm radius was used as a soil container and filled with uniform moist soil to 90 cm. during the experiments, the bottom 10 cm of soil in the cylinder was kept saturated. a steel bar was used a...
Novel ionic liquid polymer electrolytes based on polymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP), lithium bis(tri-fluoromethanesulfonyl)imide (LiTFSI) with different 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMITFSI) weight ratios have been synthesized and applied to quasi-solid state Li–air batteries. The morphology, electrochemical properties of prepa...
