Nuclei-rich galvanizing strategy for suppressing zinc dendrite growth

The uncontrolled growth of zinc dendrites on zinc anode hinders the application of zinc ion batteries. To solve this problem, Lu's group proposed a nuclei-rich galvanizing strategy for suppressing the zinc dendrite growth. This allows the nuclei-rich zinc electrode to cycle steadily for 1200 h and have a high Coulombic efficiency of 99.7% at 15 mA·cm⁻² with a deposited amount of 10 mAh·cm⁻². Moreover, the Zn-MnO₂ battery with a low N/P ratio of 1.9 exhibited sustained cycling life.
