The ever‐increasing consumption of a huge quantity of lithium batteries, for example, Li–MnO2 cells, raises critical concern about their recycling. We demonstrate herein that decayed Li–MnO2 cells can be further utilized as rechargeable lithium–air cells with admitted oxygen. We further investigated the effects of lithiated manganese dioxide on the electrocatalytic properties of oxygen‐reduction and...
Nanokristallines MnO2 mit Sauerstoff‐Fehlstellen wurde nach einem einfachen Verfahren durch Erhitzen des reinen Oxids in Ar oder O2 erhalten. Experimente und Rechnungen belegen, dass die katalytische Aktivität von MnO2 in der Sauerstoffreduktion durch die Einführung von Sauerstoff‐Fehlstellen in mäßiger Konzentration zunimmt.
