Lithium‐Ion Batteries: Tailored Yolk–Shell Sn@C Nanoboxes for High‐Performance Lithium Storage (Adv. Funct. Mater. 8/2017)

In article number 1606023, Chengzhong Yu and co-workers describe the synthesis of novel yolk-shell Sn@C nanoboxes via a facile, template-free strategy. The thickness of the carbon shell is proved crucial to the nanostructure and electrochemical performance. With an optimized thickness, the Sn@C nanoboxes exhibit a high specific capacity, excellent rate capability, and long cycle life as an anode in lithium ion batteries.
