A Charge Confinement Strategy for Boosting Interfacial Space Charge Storage in Manganese Ferrites Enabled by Highly Polarized Fluorinated‐Interfacial Layer for High‐Energy‐Density and Ultrafast Rechargeable Lithium‐Ion Batteries (Adv. Funct. Mater. 2

Highly Polarized Fluorinated-Interfacial Layer In article number 2408986, Won Bae Kim and co-workers report a rational charge confinement strategy that substantially boosts interfacial space charge storage and constructs a stable SEI on manganese ferrites via a conducting and highly polarized fluorinated-interfacial layer. This innovative anode effectively promotes charge transport and structural stability, and exceeds theoretically limited energy storage capacity even under fast recharging.
