The performance of zinc-ion batteries (ZIBs) is often hindered by issues such as dendrite formation, hydrogen evolution, and limited cycling stability. 1,3-Dihydroxyacetone (DHA) not only stabilizes the anode modulating anode/electrolyte interface (AEI) but also enhances electrochemical battery through its spontaneous reversible keto-enol tautomerization, reducing concentration gradient on surface. Using a combination DFT calculations experimental characterization, regulation hydrated Zn2+ structure adsorption at AEI this additive investigated. Overall, incorporating DHA extends stability Zn||Zn symmetric to 400 h, even depth discharge 56.7% (DOD). Zn||VNNC full exhibit stable for 700 cycles 5 A g-1 with low N/P ratio (2.69), while Zn||AC capacitors (ZICs) significantly enhanced. This study evaluates potential in ZIBs dynamic characteristics molecular structures.
