Taming Interfacial Ion-Dipole Interactions With d-Orbital Delocalized Electron Catalysis Expediates Low-Temperature Li Metal Batteries.

ABSTRACT: Low-temperature lithium metal batteries (LT-LMBs) are increasingly desired for higher energy density and longer lifespan. However, due to organic electrolyte solidification, LT-LMBs are impeded by huge barriers resulting from the hindrance of larger solvation shells with strong ion-dipole interactions, leading to depressive Li kinetics and severe dendrite formation. Herein, interfacial catalysis by constructing electron delocalization d-orbital metal oxides toward the ion-dipole interactions is pioneered to accelerate the larger Li(solvents)_x ⁺ dissociation under the low-temperature environment. Specifically, various kinds of d-orbital metal oxides (M = Ti, V, Fe, Co) with oxygen defect modulation are systematically screened and investigated for breaking the ion-dipol
