Nuvvon Inc. has announced a couple of developments in 2025 that advance the production of solid-state batteries, including a new state-of-the-art lab in the U.S. and a breakthrough in the scalability of solid-state pouch cells.

The company opened a new lab in Parsippany, N.J. in February that quadruples the existing floorspace and enables greater research, development, and manufacturing of solid-state pouch cells, using its novel solid polymer electrolytes to create safe lithium batteries. The facility brings research, manufacturing, and testing activities into one location, improving communication, productivity, and collaboration.

Nuvvon’s solid polymer electrolyte enables the creation of solid-state pouch cells that operate across a wide range of temperatures without the need for cooling, heating or pressure systems. True solid-state batteries use solid electrolytes throughout the cell, enhancing safety by reducing flammability, leakage, and dendrite formation risks, unlike conventional lithium-ion batteries that use liquid or gel electrolytes, the company said.

In June, Nuvvon announced that it will release the first samples of its 1-Ah and 5-Ah solid-state rechargeable Li-ion pouch cells this Fall. Scaling from 72-mAh to 1-Ah and 5-Ah pouch cells demonstrates that Nuvvon can manufacture the battery cells beyond laboratory-scale prototypes, the company said, offering scalability and compatibility with existing Li-ion manufacturing processes.

The battery cells with a NMC811 cathode feature a completely solid composition with no liquid electrolyte in the cell. Key performance characteristics include 2,000+ cycle life (1C/1C) and a wide operating temperature range of -20°C to 60°C (-4°F to 140°F). They are operational at atmospheric pressure and passed all common safety tests, including nail and thermal runaway. Full performance data is available on request.

Nuvvon will start with a baseline product that potential partners can order to test and evaluate. 10-Ah to 20-Ah cells will be available on request. The company also plans to focus on developing fast charge/discharge and extreme high/low temperature variants tailored to customer specific applications.
