Open Image…Save ImageOpen Image (using #TmpD/ia)… A joint research group from Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) and Humboldt-Universität zu Berlin has investigated new combinations of electrolyte solutions and electrode materials for sodium ion battery chemistry. The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. The study findings have been reported entitled “Co‐Intercalation […]

City University of Hong Kong researchers have announced two new hydrogen production catalysts based on mineral gel and ‘crystalline-amorphous’ dual-phase nano-aluminum alloy. In the first topic the researchers’ findings have been published in the scientific journal Nature Communications under the title “Two-dimensional mineral hydrogel-derived single atoms-anchored heterostructures for ultrastable hydrogen evolution”. The first author of […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Lawrence Berkeley National Lab scientists have measured the highest toughness ever recorded of any material. The discovery came while investigating a metallic alloy made of chromium, cobalt, and nickel. Not only is the metal exceptionally strong and ductile, its properties become enhanced as it gets colder. This runs counter to most other materials in […]

DOE/SLAC National Accelerator Laboratory researchers reported a polymer-based electrolyte makes for batteries that keep working – and don’t catch fire – when heated to over 140° F. Rechargeable lithium-ion batteries power phones, laptops, other personal electronics and electric cars, and are even used to store energy generated by solar panels. But if the temperature of […]

Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) researchers reported a new world record for tandem solar cells consisting of a silicon bottom cell and a perovskite top cell. The new tandem solar cell converts 32.5 percent of the incident solar radiation into electrical energy. The certifying institute European Solar Test Installation (ESTI) in Italy measured […]
