Published: April 8, 2024

Abstract Cobalt‐free and spinel LiNi 0.5 Mn 1.5 O 4 (LNMO) cathodes commonly suffer from undesirable solvent decomposition, serious transition‐metal dissolution, unstable cathode electrolyte interphase (CEI) layers, incurring rapid capacity decay at high voltages low temperatures. Herein, these issues are well addressed by utilizing fluorinated solvents with a coordination number ethyl propionate melting point. A Li 2 CO 3 /LiF‐rich heterostructured CEI layer, which possesses good electron blocking capability of LiF, fast + transport kinetics mechanical stability, is generated the synergistic decomposition hybrid solvents. The robust, homogeneous, well‐balanced layers subsequently prevent catalyzed parasitic side reactions, prohibit ensure interfacial reaction crossover to LNMO cathode, thus improving its cycling stability. Consequently, delivers high‐capacity retention 95.8% over 500 cycles 25 °C 97.5% after 180 −20 °C. This work provides an encouraging alternative design high‐voltage low‐temperature for pushing ongoing research stabilize Co‐free materials toward practical applications.
