Invited for this month's cover picture is the group of Prof. Keun Yong Sohn and co‐workers at Gimhae, Gyeongnam (Korea). The cover picture shows the successful doping of conductive cobalt into silicon nanoparticles as a negative electrode for lithium‐ion rechargeable batteries. The doped cobalt effectively suppresses the structural changes of the silicon nanoparticles and facilitates lithium‐ion diffusion kinetics, thus resulting in superior rate capability and high specific energy capacity with long‐term cyclic stability, which can potentially be used for future energy storage applications.
