“…S7,† the above two reduction peaks no longer appear in the following charging and discharge processes, which means that a stable SEI film is formed during the first cycle. 7,42 The above two reduction reactions are irreversible and consume Li ions in the electrolyte, increasing irreversible capacity loss. The potentials of lithium intercalation and the alloying reaction for d-SiO-G@C and d-SiO-G-5% materials are between 0 and 0.2 V. During the discharge process, there are three obvious reduction peaks for d-SiO-G@C, which are respectively at 0.04 V, 0.1 V, and 0.18 V. In the corresponding charging process, the oxidation potential appears at 0.11 V, 0.15 V, 0.24 V, and 0.44 V. Among them, 0.11 V, 0.15 V, and 0.24 V correspond to the delithium reaction of graphite, while 0.44 V corresponds to the oxidation reaction of Li x Si to Si.…”
