Si-C-O glass-like compound/exfoliated graphite composites for negative electrode of lithium ion battery

Abstract Two low molecular weight silicone compounds, a cyclic type having vinyl groups and a chain-type having Si–H bonds, a catalyst for curing, and a catalyst regulator were mixed. The mixture was impregnated into exfoliated graphite (EG) by sorption, and cured in air at 200 °C. By this process cross-linked silicone coatings were formed on graphite flakes. The composites of Si–C–O glass-like compounds and EG were synthesized by heat treatment of this precursor at 1000–1400 °C for 1 h in argon. The composites formed at 1000–1300 °C were amorphous by XRD and had practically the same chemical composition: Si 44–45, C 27–29, O 25–26, H
