Electrically rechargeable zinc-oxygen batteries are promising for sustainable and resource-uncritical energy storage with high energy density. Their commercialization is hindered by the limited cycling stability – especially due to the zinc anode. In this study, we present a zinc anode that stands out with two advantages: The use of an energy-saving and low temperature preparation method, and the mechanical stabilization of the pore system with a lightweight anion-exchange ionomer.

Our approach increases cycling stability for both the zinc-nickel oxide hydroxide cell and the zinc-oxygen cell: Electrochemical analysis in combination with operando X-ray diffraction measurements prove that the novel zinc anode is electrically rechargeable and can be cycled up to five times more often than zinc sponge anodes without anion-exchange ionomer to a depth of discharge of 35%. Scanning electron microscopy is used to evidence that the anion-exchange ionomer stabilises the entire pore system during cycling. We furthermore analyse zinc-oxygen batteries with anion-exchange ionomer at all parts – inside the zinc sponge anode, as separator and at the cathode. These cells can be electrically recharged with unprecedented high utilization of active material, and thus highlight the benefit of introducing an ion-selective coating into alkaline batteries with zinc anode.

可再充电的锌氧电池有望以高能量密度用于可持续的和对资源无限制的能量存储。有限的循环稳定性（特别是由于锌阳极）阻碍了它们的商业化。在这项研究中，我们提出了一种锌阳极，该锌阳极具有两个优点：使用节能的低温制备方法，以及使用轻量级的阴离子交换离聚物对孔系统进行机械稳定。

我们的方法提高了锌-氧化镍氢氧化物电池和锌-氧电池的循环稳定性：电化学分析与操作性X射线衍射测量相结合，证明新型锌阳极具有可充电性，并且可以循环使用多达五次通常比没有阴离子交换离聚物的海绵锌阳极放电深度达到35％。扫描电子显微镜用于证明阴离子交换离聚物可在循环过程中稳定整个孔系统。此外，我们还分析了在所有部位均具有阴离子交换离聚物的锌氧电池-在海绵锌的内部，作为隔板和在阴极。这些电池可以充满空前的高活性物质充电，
