The high energy density and long cycling life of zinc-based batteries are restricted by the single electro-chemical reaction system.To improve the electrochemical performance of batteries,electrode materials,electrolytes and membranes are regularly modified,while the construction of battery systems is often ne-glected.Herein,a multifunctional electrode was prepared via 3D printing,which successfully coupled the metal oxide/hydroxide-zinc battery(MZB)reaction and rechargeable zinc-air battery(RZAB)reaction.The ultrathick hierarchical 3D electrode provided a tunable capacity for the MZB system,which enabled the possibility for feasible output regulation of this hybrid system.The active material NiCoLDH was discov-ered to undergo structure reconstruction during cycling,which revealed the capacity fading mechanism.The delicate system design and discovery ensured a high-performance battery configuration and revealed the corresponding mechanism,opening a new avenue for developing high-performance zinc batteries.
