Carbon Nanopatch‐Decorated Defect‐Rich Regions for Stable Zinc Metal Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To improve the stability of Zn anodes, a carbon‐nanopatch strategy based on candle‐flame pyrolysis is proposed. After rinsing, carbon nanoparticles are mainly retained in defect‐rich regions on the Zn surface, where they help alleviate local field intensification, improve interfacial uniformity, and mitigate parasitic reactions.
