Crossover Effects of Transition‐Metal Ions on Lithium‐Metal Anode in Localized High Concentration Electrolytes

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the impact of transition‐metal (TM) ions (Ni2⁺, Mn2⁺, Co2⁺) on the performance of lithium‐metal anode in localized high‐concentration electrolytes. Mn2⁺ and Co2⁺ destabilize SEI and CEI layers, causing capacity fade and overpotential, while Ni2⁺ shows minimal effects. These findings underscore the need for electrolyte optimization

Superionic Disulfonic Acid Polymers

open access: yesAdvanced Functional Materials, EarlyView.
A strategy is presented to enhance the mechanical and ion transport properties of acid‐functionalized polymers through controlled polymerizations of precisely designed disulfonic acid monomers with well‐defined functional group arrangements. This approach allows for fine control over molecular interactions, and unexpected hydrophobic characteristics ...
