Solvay doubles PVDF capacity in China ahead of schedule to meet growing demand for EV batteries

Share to

Solvay’s Changshu site has significantly increased production capacity for Solef® PVDF, demonstrating the Group’s commitment to meeting the needs of customers worldwide.

Solvay continues to extend its leadership position in the global lithium-ion battery market with the early completion of its PVDF capacity increase in Changshu, China. The Group has now more than doubled the onsite production volume of its high-performance polymer Solef® polyvinylidene fluoride since mid-May 2022.

The rapid growth of electric and hybrid vehicles is driving record demand for PVDF. This thermoplastic fluoropolymer is used both as a binder and a separator coating in lithium-ion batteries. It plays an essential role in ensuring that batteries perform better, last longer and operate safely. Developed using Solvay’s research and innovation expertise in fluorinated chemistry and polymerization technology, Solef® PVDF is an industry-leading product, inspiring the continuous development of new solutions that will help meet customers’ needs both now and in the future.

Solvay also recently announced significant investment in Solef® PVDF production at its site in Tavaux, France, which will turn it into the largest PVDF production site in Europe. The increased  production capacity in China serves as further evidence of the Group’s deep commitment to ensuring that material is readily available to customers worldwide

“Demand for lithium-ion batteries is undergoing massive growth," said Francescantonio Azzariti, Head of Commercial for Solvay's Battery Platform. “We are inspired both by the environmental benefits as we transition to cleaner mobility and by the commercial opportunities these new technologies offer.”

Solvay's plans exemplify the execution of its Solvay One Planet sustainability ambitions and G.R.O.W. strategy, which focuses investments on high-growth, sustainable solutions that are aligned with important emerging megatrends. Solef® PVDF has also been recognized as a sustainable and profitable solution by the World Alliance for Efficient Solutions, and was an essential component of the Solar Impulse aircraft, the world's first solar-powered aircraft to circumnavigate the world.
