Major Research Areas
Development of separators for lithium-ion secondary batteries
An advantage of our separators is the coating of a heat-resistant layer formed from aramid resin, which offers high thermal stability, on a polyolefin film, thereby contributing to improvements in the safety of batteries, which have increasingly larger capacities. In response to the rapid growth in the market for lithium-ion secondary batteries, we are increasing production capabilities and developing products that address customer needs.
Development of high performance engineering plastics
High performance engineering plastics
Sumitomo Chemical’s high performance engineering plastics are used in a wide range of applications, including electrical and electronic components, separation membrane materials, and carbon fiber composite materials for aircraft. We strive to create new high-performance products that meet contemporary demands, including for improvements for the different applications, digital transformation, and energy and resource savings.
