a, DEMS of G0, G4 and G6 in a CV test in a voltage range of 2.2–4.8 V with 0.1 mV s−1 scan rate. The weights of all G0, G4 and G6 active materials were from 8.0 to 9.0 mg. The mass spectra of m/z = 32 for O2 and m/z = 44 for CO2 were collected in the initial two positive scanning sweeps. b, Charge/discharge profiles of G0, G4 and G6 in the first cycle at 0.1C (1C ≡ 250 mA g−1). c, Discharge profiles of G0 and G4 for 200 cycles at 0.2C and 25 °C after five formation cycles at 40 °C and 0.1C. d, Discharge capacity, average discharge voltage and energy density of G0 and G4 at 0.2C collected from c. e,f, CV of G0 (e) and G4 (f) in the 2nd and 50th cycles.
