Utilizing Cyclic Voltammetry to Understand the Energy Storage Mechanisms for Copper Oxide and its Graphene Oxide Hybrids as Lithium-Ion Battery Anodes.

Invited for this month's cover is the group of Robert A. W. Dryfe at the University of Manchester in collaboration with William Blythe Ltd. (Lancashire). The image shows bees building a graphene-containing battery that powers an external circuit, depicted by a purple curve. This curve represents a cyclic voltammogram, specifically of copper oxide during a charge/discharge cycle in a Li-ion half-cell, as presented in the article. The use of bees has both scientific and geographic significance. For the former, bees are assisting in building the honeycomb-like hexagonal graphene lattice, just as they do in nature. Geographically, bees are symbolic to the locations of both collaborators on this project, the University of Manchester and William Blythe (Lancashire).
