Zinc-air batteries are an attractive energy storage technology due to their high energy density, environmental friendliness, and cost-effectiveness. They are based on electrochemical reactions between zinc and oxygen from air offering a promising alternative to lithium-ion batteries. The addition of quantum sensors enable huge potential in monitoring internal dynamics of these batteries.
In this work we present a possible zinc-air battery cell design suitable for quantum sensors based on microdiamonds containing NV centers.The cell includes a zinc anode, nickel and gas discharge sheets for charging and discharging, and a KOH aqueous electrolyte. Additionally, it features an optical access to monitor the cell dynamics.
