摘要

A high-capacity stretchable graphitic carbon/Si foam electrode is enabled by a conformal self-healing elastic polymer coating. The composite electrode exhibits high stretchability (up to 88%) and endures 1000 stretching-releasing cycles at 25% strain with detrimental resistance increase. Meanwhile, the electrode delivers a high reversible specific capacity of 719 mA g(-1) and good cycling stability with 81% capacity retention after 100 cycles.
