German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.Researchers from Germany's Karlsruhe Institute of Technology (KIT) and the Helmholtz-Institut Ulm (HIU) have built a lithium-metal battery with a new combination of cathodes and electrolytes, which they claim can help the device reach an energy density of 560 watt-hours per kilogram. The battery is based on a low-cobalt, nickel-rich layered cathode known ...Den vollständigen Artikel lesen ...
