α-MnO₂ Nanowires: A Catalyst for the O₂ Electrode in Rechargeable Lithium Batteries

Higher‐capacity lithium batteries can be fabricated by using α‐MnO2 nanowires as the catalyst in a porous, composite oxygen cathode. In the depicted scanning electron micrograph of a composite positive electrode, deposits of Li2O2, which accumulates during discharge, can be seen within a porous matr...

Zusammenfassung:Higher‐capacity lithium batteries can be fabricated by using α‐MnO2 nanowires as the catalyst in a porous, composite oxygen cathode. In the depicted scanning electron micrograph of a composite positive electrode, deposits of Li2O2, which accumulates during discharge, can be seen within a porous matrix consisting of α‐MnO2 and carbon.
