Ni‐Ion‐Chelating Strategy for Mitigating the Deterioration of Li‐Ion Batteries with Nickel‐Rich Cathodes (Adv. Sci. 5/2023)

Lithium‐Ion Batteries Structural insights into a tricoordinate phosphorous compound can enhance the efficiency of chelating strategies in tackling Ni‐ion dissolution from Ni‐rich cathodes. In article number 2205918, Nam‐Soon Choi and co‐workers present a phosphine‐based compound that provides effective donor ligands and is capable of forming complexes with Ni(2+) dissolved in electrolytes, leading to the realization of high‐energy‐density lithium‐ion batteries.
