Abstract
we use SiO and Li₁₃Si₄ (lithium accounted for 10% of the mass fraction of the whole material) in a closed space to weigh and mix after ball milling, and then heated at 750 and 950 degrees Celsius respectively. Try to use the mechanical encapsulation of lamellar graphene to cover the mixed material of SiO and Li₁₃Si₄, so as to try to improve SiO-based anode performance. Both graphene and lithium silicon alloy will contribute to the higher reversible capacity and long-term stability, realizing the application of SiO anodes.
