Showa Denko Packaging Co., Ltd. (SPA), a consolidated subsidiary of Showa Denko K.K. (SDK), has developed a new product for its SPALF line of aluminium laminate films for packaging small-scale pouch type lithium-ion batteries (LIBs) and will install equipment to mass produce the new product, for large-scale LIBs and use in electric vehicles (EVs). The new production facility is scheduled for operation in March 2021.
SPALF is a laminated composite film consisting of resins and aluminium foil, mainly used as packaging material for small-scale pouch type LIBs. SPALF enjoys a large global market share due to its superb insulation qualities and plasticity. It is more flexible for molding, more lightweight, and with better heat radiation characteristics than metal, so used as casing for small LIBs in devices such as smartphones and tablets.
Recognised for its high quality with safety evaluations progressing, it is increasingly used in large-scale LIB applications, such as EVs. As the EV market is developing in China, following Europe, the Showa Denko Group has decided to install facilities to mass produce SPALF for large-scale LIBs.
The global demand for LIBs (in electrical applications) is expected to increase 30% a year until 2025. The Showa Denko Group produces and sells various LIB materials with distinguishing advantages, such as SPALF, VGCF additives for anode/cathode materials, and POLYSOL aqueous binding resin.
By increasing sales of these LIB materials, the group aims to contribute to the growth of the LIB market and the improvement of LIB functionality.
