Abstract

original image

CuO/Cu electrodes comprising a surface layer of a densely packed array of unusual cog-shaped CuO microparticles with hierarchical nanofilament-based superstructures are presented by Stephen Mann and co-workers on page 3516. The electrodes demonstrate an improvement in coulombic efficiency, specific capacity, and cycling performance as anodes in lithium-ion batteries. The initial discharge capacity and reversible capacity are higher than for most copper oxide materials used.
