Chemists from the University of Waterloo have successfully resolved two of the most challenging issues surrounding lithium-oxygen batteries, and in the process created a working battery with near 100 per cent coulombic efficiency. The new work, which appears this week in Science, proves that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The team is the first to achieve four-electron conversion,

Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult for the starting material for the reaction – hydrogen – to reach the enzyme-loaded electrode. Researchers solved this problem by combining previously developed

If you’ve ever used a smartphone for more than a year or two, you know that the lithium ion batteries degrade over time and refuse to hold a charge like they used to when they were new—but the reason why has been little understood. But research published today in Nature Materials could have a few answers. A group of researchers

A new type of battery developed by researchers at MIT could be made partly from carbon dioxide captured from power plants. Rather than attempting to convert carbon dioxide to specialized chemicals using metal catalysts, which is currently highly challenging, this battery could continuously convert carbon dioxide into a solid mineral carbonate as it discharges. While still based on early-stage research

TDK Corporation has extended the lineup of proven CeraLink™ capacitors with CeraLink FA types in modular flex-assembly technology. This space-saving design connects two, three or ten identical capacitors in parallel over the same terminals in order to increase the capacitance. Thanks to their low parasitic effects, CeraLink capacitors are ideally suited for converter topologies on the basis of fast-switching semiconductors
