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.
