Biomimetic Honeycomb Zn Anode Enabled Multi‐Field Regulation toward Highly Stable Flexible Zn‐Ion Batteries

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(25)

Published: March 21, 2023

Abstract Flexible Zn‐ion batteries (ZIBs) emerge as a promising entrant for flexible and safe energy systems in the post‐Li era, while instability of Zn anode including inferior flexibility, uncontrollable plating, dendrite growth remains challenge. Naturally inspired, topology‐optimized biomimetic honeycomb (BH‐Zn) through mechanical‐electrochemical processing is demonstrated. Numerical simulations experimental observations reveal BH‐Zn engenders smooth current–stress–thermal field distributions, concurrently realizing multi‐field regulation effect boosted stability. After situ alloying, enables half‐diminished voltage polarization, superior electrochemical stability 2000 h cycling, thermal even at 30 mA cm −2 . Moreover, assembled ZIBs manifest over 20 times enhanced capacity retention are integrated self‐powered wearable system real‐time health monitoring. This strategy can be extended to customizable metal anodes promises applied stable batteries.
