Engineering the formulation of an Mn-based positive electrode is a viable strategy for producing efficient aqueous zinc-ion battery. However, Mn dissolution and byproducts result in capacity fading, thus limiting its electrochemical performances. To solve undesirable issues, concept in-situ forming electrode/electrolyte interface on commercial MnO2 designed, with help introducing Dioctyl Phthalate into ZS-based electrolyte (2 M ZnSO4 + 0.2 MnSO4), designated as ZS-DOP electrolyte. An advanced three-dimensional chemical imaging analysis model material reveals dynamic formation interface. The formed organic effectively suppresses corrosion electrolytes hydrophobicity, adjusts pH value according to Le Chatelier's Principle inhibit production by-products. Specifically, pouch cell assembled attains reversible ~2.5 Ah powers unmanned aerial vehicle. Furthermore, photovoltaic energy storage applications deliver stable 0.5 realize power supply mobile phones other electronic devices. Our results facilitate development surface protection battery, providing insights practical application.

Zinc-ion batteries (ZIBs) have attracted widespread attention in recent years. However, due to the aqueous electrolyte's high activity, zinc anode is affected by severe side reactions such as corrosion and hydrogen evolution, resulting poor reversibility. Inspired structure of a lipid bilayer biology, this paper, we introduce lithium nonafluorobutylsulfonate inhibit water activity via vigorous binding between S═O H2O form lipid-like protective on surface anode, thereby improving reversibility extending lifespan ZIBs. The biomimetic electrolyte demonstrated outstanding with 880 h cycle life 99.91% average Comlombic efficiency Zn||Cu asymmetric battery, well 2460 cumulative capacity 6 Ah cm-2 Zn||Zn symmetric battery (5 mA 5 mAh cm-2). In addition, full cells Zn0.25V2O5·nH2O MnO2 show excellent retention 91.67% after 1200 cycles 100% 1000 cycles, respectively. After ampere-hour-level pouch cell showed rate 93%. This method provides strategy for constructing electrolytes improve anodes.

Aqueous zinc-ion batteries have promising potential as energy storage devices due to their low cost and environmental friendliness. However, development has been hindered by zinc dendrite formation parasitic side reactions. Herein, we introduce a low-concentration sodium benzoate (NaBZ) electrolyte additive stabilize the electrode–electrolyte interface promote deposition on Zn (002) crystal plane. From experimental characterization computational analyses, NaBZ was found adsorb surface inhibit reactions while guiding homogeneous Consequently, Zn|Zn symmetric cells with cycled stably for over 1000 h at current density of 0.5 mA cm–2 an areal capacity mAh cm–2, Zn|Cu showed excellent reversibility Coulombic efficiency 99.05%. Moreover, Zn|Na0.33V2O5 full achieve high specific 124 g–1 cycling 600 2 A g–1. These findings present low-cost modification strategy reversible batteries.
