AI Technical Summary
Technical Problem
Existing zinc-air batteries use precious metal catalysts, which are costly and have poor stability. The gas diffusion layer is prone to leakage, leading to a decline in battery performance.
Method used
Using a non-metallic PNC catalyst, a highly stable porous network electrode structure is formed by setting an anti-leakage layer, carbon cloth, and catalytic composite layer between the electrode anode and cathode. This avoids electrolyte leakage and reduces costs through carbon cloth protection.
Benefits of technology
This improved the oxygen reaction rate of the zinc-air battery, enhanced the functionality and practicality of the electrode, and reduced the cost of the catalyst.
