From: Li2SO4 coating for enhanced electrochemical performance of Co-free, Li-rich layered oxide cathode
Figure 4. Electrochemical performance charts of LLC, CF-LLC and S-CF-LLC: (A) 1st cycle charge-discharge curves; (B) specific discharge capacity across 100 cycles; (C) Coulombic efficiency across 100 cycles; (D) midpoint voltage across 100 cycles; (E) specific discharge energy across 100 cycles; (F) Rate capability test of CF-LLC and S-CF-LLC. C-rate was increased sequentially from 0.1, 0.2, 0.5, 1, 2 C with 5 cycles per C-rate, after which the C-rate was returned to 0.1 C. CF-LLC: Co-free, Li-rich layered oxide cathodes;
