Breakthrough for rechargeable non-aqueous magnesium-metal battery that would be twice as good lithium ion batteries

Scientists at the Department of Energy’s National Renewable Energy Laboratory (NREL) have discovered a new approach for developing a rechargeable non-aqueous magnesium-metal battery. Scientists have pioneered a method to enable the reversible chemistry of magnesium metal in the noncorrosive carbonate-based electrolytes and tested the concept in a prototype cell. The technology possesses potential advantages over …

Toyota has reduced the rare earth materials used in electric vehicle magnets by 50%

Toyota has developed the world’s first neodymium-reduced, heat-resistant magnet. Neodymium magnets are used in various types of motors such as the high-output motors found in electrified vehicles, use of which is expected to increase rapidly in the future. The new magnet uses significantly less neodymium, a rare-earth element (“rare earth”), and can be used in …

Lithium metal electrode batteries

Reversible lithium metal electrode has potential to almost double the energy density of lithium-ion batteries and lower the cost to $100 per kilowatt hour. Researchers identified critical parameters against which to assess progress and provided a summary of published efforts. Using lithium (less than 30 microns) rather than thick lithium foils for numerous reasons, including …
