abstract = "Nowadays, research aimed at the development of materials with increased energy density for lithium-ion batteries are carried out all over the world. Composite anode materials based on Si and C ultrafine particles are considered promising due to their high capacity. In this work, a new approach for carbothermal synthesis of C/SiC composite mixtures with SiC particles of fibrous morphology with a fiber diameter of 0.1-2.0 mu m is proposed. The synthesis was carried out on natural raw materials (quartz and graphite) without the use of complex equipment and an argon atmosphere. Using the proposed method, C/SiC mixture as well as pure SiC were synthesized and used to manufacture anode half-cells of lithium-ion batteries. The potential use of the resulting mixtures as anode material for lithium-ion battery was shown. Energy characteristics of the mixtures were determined. After 100 cycles, pure SiC reached a discharge capacity of 180 and 138 mAh g(-1) at a current of C/20 and C, respectively, and for the mixtures of (wt%) 29.5C-70.5 SiC and 50Si-14.5C-35.5SiC discharge capacity of 328 and 400 mAh g(-1) at a current of C/2 were achieved. The Coulombic efficiency of the samples during cycling was over 99%.",
