Ge decoration of Si@C core‐shell nanoparticles is easily achieved by a sol‐gel method and applied in lithium ion battery anodes, as described by Y. X. Wang, J. P. Yang, and co‐workers on page 7800. The Ge nanograins enhance electrode capacity and ensure a high rate capability by accumulating Li ions and by facilitating their efficient transfer. Structural stability and electrochemical kinetics are also enhanced.
