Abstract Aqueous zinc‐selenium (Zn‐Se) batteries have garnered much attention due to their inherent safety and high specific capacity. Unfortunately, the problem of sluggish redox reaction represents a significant obstacle development aqueous Zn‐Se batteries.

Abstract The crosstalk of transition metal ions between the oxide cathode and Zn anode restricts practical applications aqueous zinc‐ion batteries (ZIBs). Herein, we propose a decoupled electrolyte (DCE) consisting nonaqueous‐phase (N‐phase) anolyte an aqueous‐phase (A‐phase) catholyte to prevent Mn 2+ , thus extending lifespan MnO 2 ‐based ZIBs. Experimental measurements theoretical modelling verify that trimethyl phosphate (TMP) not only synergistically works with NH 4 Cl in N‐phase enable fast conduction while blocking diffusion toward anode, but also modifies solvation structure suppress dendrite formation corrosion on anode. Meanwhile, A‐phase effectively accelerates reaction kinetics. as‐developed Zn|DCE|MnO cell delivers 80.13 % capacity retention after 900 cycles at 0.5 A g −1 .

Abstract In tackling the stability challenge of aqueous Zn‐ion batteries (AZIBs) for large‐scale energy storage, adoption electrolyte additive emerges as a practical solution. Unlike current trial‐and‐error methods selecting additives, data‐driven strategy is proposed using theoretically computed surface free descriptor, benchmarked against experimental results. Numerous additives are calculated from existing literature, forming database machine learning (ML) training. Importantly, this ML model relies solely on values, effectively addressing large solvent molecule models that difficult to handle with quantum chemistry computation. The interpretable linear regression algorithm identifies number heavy atoms in and liquid tension key factors. Artificial intelligence (AI) clustering categorizes molecules, identifying regions most significant impact enhancing battery stability.
