Biomimetic honeycomb Zn anode enabled multi-field regulation toward highly stable flexible Zn-ion batteries

Flexible Zn-ion batteries (ZIBs) emerge as a promising entrant for flexible and safe energy systems in the post-Li era, while the instability of Zn anode including inferior flexibility, uncontrollable plating, and dendrite growth remains a challenge. Naturally inspired, a topology-optimized biomimet...
