Nuvvon Inc. this week announced a significant advance in the scalability of its solid-state rechargeable lithium-ion batteries, with plans to distribute 1 Ah and 5 Ah pouch-cell samples this fall. The company, headquartered in Parsippany, New Jersey, has moved beyond its earlier 72 mAh prototypes by leveraging proprietary solid polymer electrolyte (SPE) technology that is compatible with existing lithium-ion manufacturing infrastructure.
“This is a real breakthrough moment for Nuvvon,” notes Jonathan Lex, Chief Operating Officer of Nuvvon Inc. “While we’ve always maintained that our technology is inherently scalable and compatible with existing lithium-ion manufacturing infrastructure, we focused first on advancing our materials science. Now, we have validated our approach by successfully producing larger format cells, paving the way for faster commercialization.”
Key performance metrics for the new SPE cells include a cycle life exceeding 2,000 cycles at a 1C charge/discharge rate paired with an NMC811 cathode, and a broad operating temperature range from –20 °C to +60 °C (–4 °F to 140 °F). Nuvvon also highlights the cells’ fully solid composition—eliminating all liquid electrolyte—and their ability to pass standard safety tests such as nail penetration and thermal-runaway assessments, all while operating at atmospheric pressure.
“Progress has accelerated beyond expectations since the expanded team moved into our new, larger facility,” explains Dr. Simon Madgwick, Nuvvon CEO. “We know our product is unique – a completely solid compressionless cell – and now is available at commercial grade and made entirely on the existing Li-ion process. It has been a lot of hard work and, with some ongoing testing to finish, we will be ready to take orders for pilot samples.”
Initially, Nuvvon will offer a baseline cell for evaluation, while concurrently developing variants optimized for fast charge/discharge performance and extreme-temperature environments. Customers may also request larger 10–20 Ah formats for specific applications.
Founded in 2017, Nuvvon is a solid-state battery materials company focused on novel polymer electrolytes for next-generation rechargeable batteries. The company’s research and production are based in Parsippany, New Jersey.
