Showa Denko KK (SDK), a subsidiary of Showa Denko KK (SPA), has developed a new product that will become a SPALF aluminum-plastic composite film (mainly used as a soft-pack lithium-ion battery (LIB) Packaging materials) new members of the product line, SPA will start mass production of this new product. The new product is mainly designed for large-size lithium-ion batteries used in electric vehicles, and is expected to be put into production in March 2021.
SPALF is a composite film made of resin film and aluminum foil, which is mainly used as a packaging material for soft pack lithium ion batteries. SPALF is excellent in electrical insulation, plasticity and corrosion resistance.
The shape of the soft battery is very flexible, so it can be used in various small devices such as smart phones and tablet computers. In addition, in recent years, soft-packed lithium-ion batteries have been widely recognized for their high quality, and have made great progress in verifying safety, so they have also begun to be widely used in large-scale equipment such as electric vehicles. The continuous development of electric vehicles in countries such as China and Europe has led to an increase in demand for soft-pack lithium-ion batteries. Therefore, Showa Denko Co., Ltd. developed the SPALF aluminum-plastic composite film for large-size soft-pack lithium ion batteries.
Showa Denko's vision is to be a KOSEIHA company (personalized company), that is, to ensure that various KOSEIHA businesses maintain a high level of profitability and stability for a long period of time. By 2025, the global demand for lithium-ion batteries is expected to grow at an annual rate of 30%. Showa Denko Co., Ltd. produces and sells various lithium ion battery materials with unique advantages, such as SPALF aluminum-plastic composite membranes, VGCFTM additives for anode / cathode, POLYSOLTM water-soluble resin, etc. The company will expand its influence in the lithium-ion battery market by increasing the sales of such lithium-ion battery materials, improve the functions of lithium-ion batteries, and grow the company's lithium-ion material business into the KOSEIHA business in the field of advanced battery materials.
