Figure 3. (A) Rate performance, (B) discharge capacities and coulombic efficiencies of pouch cells at 0.2 C; (C) initial charge/discharge profiles of pouch cells; (D) GITT profiles and Li⁺ diffusion coefficient of both samples; dQ/dV profiles of (E) P-NCM and (F) C-NCM samples after cycles; (G) O₂ and (H) CO₂ release from both samples during heating process in the TG-MS testing. GITT: Galvanized intermittent titration technique; TG-MS: thermogravimetric analysis-mass spectroscopy; C-NCM: C₆₀-COOH modified NCM811; P-NCM: pristine NCM811.
