Press Release, 10 December 2025
A new solid-state battery pack co-developed by BASF and Welion New Energy Technology has made its public debut at the 23rd Guangzhou International Automobile Exhibition — presenting a potentially major leap forward for electric vehicle safety and efficiency. The pack integrates BASF’s advanced materials such as Ultramid®, Ultradur® engineering plastics, and a suite of polyurethanes including Elastolit®, Elastoflex®, Elastan®, and Elastocoat®. These help cut pack weight, improve thermal management, and significantly bolster safety performance.
Compared with traditional metal-based battery enclosures, BASF’s lighter-weight materials deliver nearly a 50% reduction in pack weight, which can translate to better vehicle range and efficiency. Flame-retardant cell holders, high-voltage busbars with superior fire-resistant compounds, and fire-protection coatings work together to guard against thermal runaway, overcharging, short circuits, and mechanical impact — helping meet China’s GB 38031 safety standard while aligning with global battery safety norms.
According to Welion Chairman Huigen Yu, this collaboration signals a turning point: by removing flammable liquid electrolytes typically used in EV batteries, the solid-state design boosts thermal stability, addresses charging-speed and driving-range challenges, and brings forward safer, more reliable electric vehicles for the mainstream.
With this unveiling, BASF and Welion underline how high-performance materials and smart design can accelerate the broader adoption of EVs — proving that innovation beneath the hood can be just as important as the vehicle itself.
