Silicon Powders

[INQ. NO. 2408M27] Since its establishment in 2008, Korea Metal Silicon Co., Ltd. (KMS) has specialized in “silicon,” a core material in various industrial fields.
From 2017 to 2018, KMS partnered with Research Institute of Industrial Science & Technology (RIST), the research institute utilized by POSCO group, and LG Chem, the predecessor of LG Energy Solution, to produce composite anode material with graphite and silicon through utilizing its own nano-silicon technology.
Furthermore, KMS has developed “Pure SiliconTM” in collaboration with LG Energy Solution. Pure SiliconTM is the stand-alone active material for LIB (lithium-ion battery) anode materials.
Pure SiliconTM has a micrometer particle size and a special particle size distribution, so Pure SiliconTM is used as the sole active material without carbonaceous active materials such as graphite. Pure SiliconTM is a registered trademark of KMS.

Metal silicon powder
Metal silicon is a material manufactured by reducing silica, and is used as the main raw material for polysilicon, a core material for alloys, semiconductors, and solar energy. It is widely used in secondary battery anode materials, special industrial gases, and organic silicone manufacturing.

Silicon powder for lithium-ion battery
Currently, silicon is used as an anode active material in lithium-ion batteries. Silicon has a larger capacity and faster charge/discharge speed than the existing material graphite. Silicon is applied to the anode in various forms such as SiOx, Si/C, Pure SiliconTM and silicon nanowire.
KMS possesses technologies and patents that can produce high-quality silicon powder at high yields, so KMS produces and supplies silicon powder of purity and particle size that meets customer requests. KMS is the only domestic company that produces metal silicon powder from non-Chinese raw materials.
