Figure 7. (A) Schematic diagram of the synthesis process for Se-LNO. Long-term testing of LNO and Se-LNO at 1 C and cutoff voltages of 2.8-4.3 V over 300 cycles. This figure is quoted with permission from Chu et al.^[73]. (B) Schematic illustration of the advantages and cycling performance of the dual-protection PP-coating layer. This figure is quoted with permission from Kim et al.^[15]. (C) Differences in mechanism and effects of low-valence (Al) and high-valence (Nb, Ta, and Mo) dopants, including the incorporation into bulk and the grain boundary coating, (D and E) Cycling performance (0.5 C, 2.7-4.3V) of half-cells featuring LNO, Al-LNO, Nb-LNO, Ta-LNO, and Mo-LNO cathodes calcined at 650 °C (D) and their respective optimized calcination temperatures (E).
