Improving bifunctional catalytic activity of biochar via in-situ growth of nickel-iron hydroxide as cathodic catalyst for zinc-air batteries
| • | Heteroatom-doped wood-derived biochar was assisted in situ growth of NiFe-LDH. |
| • | NiFe-LDH@NC exhibited excellent bifunctional activity and stability toward ORR/OER. |
| • | The ZAB achieved a peak power density of 123 mW cm−2 and a cycling stability of 270 h. |
