    SiO vs Graphite

    • Graphite, with its exceptional capacity retention rate, is widely used in secondary batteries. However, its capacity is inherently limited due to material constraints.
    • Silicon, offering ten times the theoretical capacity of graphite, is proposed as an alternative. Yet, challenges like short circuits, fires, and explosions, etc. within the electrode caused by the high volume expansion of silicon must be addressed.
    • The SiOx anode material overcomes the stability issues of conventional silicon while simultaneously delivering high volumes.
    POSCO Silicon Solution Co., Ltd's high-performance silicon oxide anode materials

    Through our unique silicon oxide manufacturing technology, high energy densities have been achieved, and volume expansion issues have been resolved.
    We have successfully developed the world's first high-temperature liquid process (patented domestically, applications filed in major international markets).

    Resulting in effective pricing with lower
    production costs, compared to competitors.
