Abstract

The relationship between surface coverage of the shell layer in core-shell nanostructured electrodes and the resulting electrochemical performance of the electrodes is described. Systematic studies and theoretical modeling reveal that partially covered core-shell nanostructured electrodes are beneficial to release the stress induced by lithiation and delithiation, leading to the excellent cycle performance without any capacity fading up to 50 cycles.
