Nuvvon has announced a milestone in the development of solid-state lithium-ion batteries, with the upcoming release of 1Ah and 5Ah pouch cell samples scheduled for Fall 2025.
These larger-format cells mark a transition from lab-scale prototypes to commercial-grade energy storage solutions, supporting the growing demand for advanced battery technologies in electric vehicles (EVs), aerospace, and defense applications.
The new pouch cells are based on Nuvvon’s proprietary solid polymer electrolyte (SPE) technology. This fully solid-state design eliminates the need for any liquid electrolyte, improving safety while maintaining compatibility with existing lithium-ion manufacturing infrastructure.
Key performance specifications include:
- Over 2000 cycles at 1C/1C using NMC811 cathodes
- Operational temperature range from -20° to +60° C
- Stable operation at atmospheric pressure with no need for applied stack pressure
- Compliance with industry safety tests (nail penetration, thermal runaway, etc.)
- Manufactured in the USA
This scale-up supports next-generation EV battery development by enabling higher-capacity, safer cells with improved thermal stability. The 1Ah and 5Ah samples provide OEMs and integrators a testable baseline for evaluating performance in vehicle environments. Larger 10–20Ah cells are expected to follow upon request.
In parallel with these releases, Nuvvon is also developing variants optimized for fast charging and extreme temperature performance to meet a wide range of application-specific needs.
With this step, Nuvvon aims to accelerate commercialization of solid-state battery solutions for EV and mobility platforms that demand higher energy density and robust safety without the constraints of liquid electrolyte systems.
