Electrochemical performance and microstructure of NCM622, NM64 and Co-NM64 in the full cell. (a) Discharge profiles of NCM622, NM64 and Co-NM64 using graphite as an anode within 2.7–4.4 V at 50 cycles at a current of 1 C. (b) 1 C cycling of NCM622, NM64 and Co-NM64 in the range of 2.7–4.4 V. (c) Comparison of the capacity retention between the Co-NM64 and typical cathodes previously reported for LIBs in the full cell. (d–f) HRTEM images of NCM622 (d), NM64 (e) and Co-NM64 (f) after 50 cycles. Scale bars, 5 nm (c–e), 1 nm (enlarged Figures in (d–f)).
