25 oC cycling: The capacity retention during long-term cycling is up to 95.8% after 500 cycles at 2 C

20 °C cycling: When cycled at 20 °C, LNMO exhibits a reversible capacity of 114 mAh g1 at 0.2 C with a capacity retention of 97.5% even after 180 cycles FULL CELL

Li4Ti5O12 LTO) is known as a “zero-strain materialˮ, which is suitable for pairing with LNMO for high-power applications

LNMO||LTO coin cells were fabricated over the voltage range of 2.03.5 V. Even at 30 °C, 96.0% capacity retention is achieved after 200 cycles. Source: Adv. Funct. Mater. 2024, 34, 2400996

STRUCTUREPERFORMANCE CORRELATION A Li2CO3/LiF-rich heterostructured CEI layer, which possesses the electron blocking capability of LiF, the fast Li+ transport kinetics of Li2CO3 and good mechanical stability, is generated by the synergistic decomposition of hybrid solvents. The robust, homogeneous, and well-balanced CEI layers subsequently prevent catalyzed parasitic side reactions, prohibit transition-metal dissolution, and ensure fast interfacial reaction kinetics crossover to the LNMO cathode, thus improving cycling stability of the cell.
