- As a continued effort to make Zn metal anode reversible at lower cost, researchers at ARL explored a new supporting salt based on ammonium salt to alter the interfacial structure and interphasial chemistries.
- The salt was synthesized at ARL and much cheaper than the phosphonium salt used in the prior work.
- Zn reversibility is significantly enhanced with HER suppressed, as evidenced by widened electrochemical stability window and improved Coulombic efficiency.
- The interphase chemistry brought by this ammonium salt allows a Na2V6O16-1.63H2O/Zn cell with >1,000 cycle lifetime.
- Modeling reveals a reaction pathway forming an interphase comprising ZnF2, ZnCO3, and fluoro-polymeric species.

By using Li isotopic labelling of SEIs and electrolytes followed by time-of-flight secondary-ion mass spectroscopy and solid-state NMR analyses, we found that the majority of Li+ “immobilized” in the chemical ingredients were exchanged after 1 SEI formation cycle. Ion exchange by diffusion based on concentration … Read More
