What's Happening?
Recent research has demonstrated the effectiveness of LAPONITE, a commercially available material, in improving zinc electrodeposition. The study highlights LAPONITE's ability to selectively permit Zn2+ passage while blocking SO4 2−, leading to a more uniform Zn2+ flux. This results in dense, vertically aligned zinc deposition, significantly mitigating dendrite formation compared to standard zinc. Computational fluid dynamics simulations corroborate the elimination of ion flux vortices with the LAPONITE coating. The research indicates that LAPONITE has selective interaction capabilities, resulting in a higher Zn2+ transference number for LAPO@Zn compared to bare Zn, suggesting that the current source is primarily Zn deposition rather than SO4 2−-related capacitance or ZHS formation.
