Batteries: From Checkerboard‐Like Sand Barriers to 3D Cu@CNF Composite Current Collectors for High‐Performance Batteries (Adv. Sci. 7/2018)

Inspired by the structures and functions of sand barriers in the desert region, in article number https://doi.org/10.1002/advs.201800031 Wei Yuan, Meilin Liu, and co‐workers report a 3D composite current collector with checkerboard‐like surface structure for lithium‐ion batteries. Like the windbreak and sand fixation effects of the sand barrier, the checkerboard‐like surface structure helps to effectively alleviate the pulverization of electrode materials and enhance the electrochemical performance of lithium‐ion batteries.
