Nickel-zinc (Ni-Zn) batteries are a promising technology due to their high output voltage, high theoretical specific energy, high safety and low cost. However, rechargeable alkaline Ni-Zn batteries are challenging, because the cathodic side reaction of oxygen evolution results in low energy efficiency and poor stability.
