Lithium‐Ion Batteries: A Single‐Step Hydrothermal Route to 3D Hierarchical Cu2O/CuO/rGO Nanosheets as High‐Performance Anode of Lithium‐Ion Batteries (Small 5/2018)

In article number 1702667, Jie Xiong, Weidong He, and co‐workers synthesize high‐performance Cu2O/CuO/rGO through a facile single‐step hydrothermal method and employ it as an anode of a lithium‐ion battery, delivering remarkable energy capacity, rate capacity and thermal stability. In the cover, the two “magic” hands represent the 3D hierarchical network of rGO. The robust “magic” network mitigates the volume expansion of Cu2O/CuO, facilitates the electron transfer in anode reactions, and expedites the Li+ diffusion for high‐rate charges/discharges of the lithium‐ion battery.
