Interfacial Molecular Repulsion Engineering for Durable 5 V-Class Cobalt-Free Lithium-Ion Batteries
The cobalt-free LiNi0.5Mn1.5O4 (LNMO) cathode exhibits severe interfacial instability when employed with carbonate-based electrolytes. Here, we introduce methyl(3,3,3-trifluoropropyl)diethoxysilane (MFS) as a nonsacrificial additive that creates a molecular “repulsion layer” on LNMO. MFS preferentially adsorbs onto t...
