Abstract

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.
