a Differential capacity curves of CD-LNMO, LLO, and LNMO from the 1st to 80th cycles. The cycling tests were performed from 2.0–4.8 V at a specific current of 100 mA g⁻¹, and the curves were plotted every 10 cycles. b–d The charge–discharge profile of CD-LNMO (b), LLO (c), and LNMO (d) in the first five cycles with a specific current of 100 mA g⁻¹. e Cycling tests of CD-LNMO, LLO, and LNMO with a specific current of 100 mA g⁻¹. All the tests are performed in Li-metal coin cells within 2.0–4.8 V at 25 ± 5 °C.
