Showa Denko to expand production capacities for carbon-based anode materials for Li-ion batteries

Showa Denko will expand its production capacity for SCMG carbon-based anode material used in lithium-ion rechargeable batteries (LIBs) in response to growing demand from customers.

Commercial operation of the expanded production facility is scheduled to start at the end of 2016. Through this capacity expansion, Omachi Plant’s SCMG production capacity will be increased by 50%, to 1,500t per year. In addition, SDK started to outsource a part of its SCMG production to a manufacturer in China in this June.

SCMG offers low resistance and long life, and demonstrates high performance when used in LIBs for EVs.

In January 2016, SDK also started to outsource a part of its production of SDX carbon-coated aluminum foil, which is used as collector for cathode in LIB, to a Chinese manufacturer. SDX has the advantages of low resistance and close adhesion to cathode materials in LIBs, thereby improving charge/discharge performance of LIBs and contributing to a reduction in the amount of conduction supportive agents and binders added to cathode materials in LIBs.

Demand for SDX has also been increasing especially in the field of LIBs for EVs. To meet this increase in demand, it became necessary for SDK to expand its SDX production capacity; thus, SDK started to produce SDX in China.

In addition to SCMG and SDX, SDK’s lineup of LIB materials includes aluminum laminate film (SPALF), conduction supportive agent (VGCF), and binder (Polysol).

Showa Denko K.K. is a major manufacturer and marketer of chemical products serving a wide range of fields ranging from heavy industry to the electronic and computer industries.
