Reaktor gewinnt Batterie-Lithium mit Wasser und Strom im Großmaßstab

TECH XPLORE

Ein Team an der Rice University hat einen elektrochemischen Reaktor entwickelt, der Alt-Batteriekathoden direkt in Lithiumhydroxid von >99 % Reinheit umwandelt – bei ~90 % Rückgewinnung über 1.000 Stunden und deutlich geringerer Energie­aufnahme als herkömmliche Säureverfahren.
