Nuvvon, the US-based energy storage company, has announced that it will be releasing the first samples of its 1Ah and 5Ah solid-state rechargeable lithium-ion pouch cells this autumn, as part of a breakthrough in scalability.
The firm began developing its solid-state cells from 72mAh and said it is moving beyond laboratory scale prototypes.
These solid-state pouch cells have 2,000+ life cycle and are made from an NMC811 cathode. The battery is entirely made of a solid composition with no liquid electrolyte in any part of the cell.
Nuvvon’s lithium-ion cells have a wide operating range of -20°C to +60°C and are operational at atmospheric pressure with no stack pressure.
The company claims that the solid-state cells have passed all the common safety tests, including the nail and thermal runway tests.
It will now begin with a baseline product that potential partners can request to order to test and evaluate the cells.
The firm is also focusing on developing fast charge/discharge and extreme high/low temperature variants with specific customer variants in mind. Cells between 10-20Ah will be available on request.
Jonathan Lex, chief operating officer, Nuvvon, said, “This is a real breakthrough moment for Nuvvon. 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 commercialisation.”
