“…Obviously, the voltage attenuation of NCM811 is more serious than that of NCM811@NFO-1.5, which may be caused by the irreversible structural degradation. 41 As exhibited in Figure 3e, the capacity retention has been fairly increased from 52.46% for the bare NCM811 to 80.57% for the NCM811@NFO-1.5 sample after 200 cycles. Therefore, the NFO coating could help suppress the serious degradation of the structure and inhibit the aggravation of the interfacial parasitic reaction during the cycle.…”

The interfacial instability of layered Ni-rich cathodes is acknowledged as a significant obstacle to their usefulness in cutting-edge lithium-ion batteries. Surface engineering is a good option to overcome rapid capacity decay and uncontrolled thermal runaway. Herein, an inverse spinel NiFe 2 O 4 (NFO) interface layer is built on Ni-rich LiNi 0.8 Co 0.1 Mn 0.1 O 2 materials by a simple wet chemical strategy. It is discovered that fast ion transport kinetics between particles are guaranteed by the NFO coating with good lithium-ion conductivity. Additionally, the NFO layer is characterized by high toughness and can accommodate stress changes, which can prevent an irreversible phase transformation. It also functions as a physicochemical barrier to suppress interfacial side reactions and the dissolution of transition-metal ions. The optimized Ni-rich cathode, profiting from the advantages of the lithiumion-conductive NiFe 2 O 4 coating layer, demonstrates improved high-voltage prolonged cycling durability, superior rate capability of 112.7 mA h g −1 at 10C, and high-temperature stability of 130 mA h g −1 after 100 cycles at 60 °C. Our strategy herein provides an alternative route for tuning the surface structural features of the Ni-rich cathodes for advanced lithium-ion storage applications.
