    Recently, Chengdu Sibao Technology Co.
    , Ltd.
    "a modified silicon oxide/carbon nanotube composite anode material and preparation method thereof" was authorized
    by the State Intellectual Property Office for invention patent.

    The patent innovatively uses the special structure and organic functional groups of silane coupling agents to form a solid network structure protective layer on the surface of silicon oxide through chemical reaction, so as to inhibit the cracking and volume expansion effect
    of silicon oxide.
    Carbon nanotubes have good conductivity, and the modified silicon oxide is composited to form a three-dimensional structure, which can better inhibit the volume expansion of silicon oxide, and the conductive layer is not easy to fall off, improve the conductivity of materials, improve the cycle performance of electrode materials, and improve the energy density of batteries, thereby improving the endurance of energy vehicles
    .

    Compared with the traditional graphite anode material, the battery using this material has the characteristics of low cost and high first coulombic efficiency, and has broad
    application prospects.

    According to reports, SiBao Technology has built a 50 tons/year silicon-carbon anode pilot production line in 2019, and the products have passed the evaluation
    of battery companies.
    In November 2021, the company established a wholly-owned subsidiary Sibao (Meishan) New Energy Materials Co.
    , Ltd.
    , planning to invest a total of 560 million yuan to build 10,000 tons/year silicon-carbon anode materials for lithium batteries, 40,000 tons/year special adhesive production base and lithium battery material R&D center, in preparation
    for the industrialized large-scale production of the company's silicon-carbon anode materials.
