US solid-state battery know-how developer Nuvvon’s polymer electrolyte has handed a collection of nail penetration assessments, which create a brief circuit contained in the cell to find out if the battery catches hearth or explodes.
In two units of assessments, which have been carried out at The College of Texas at Austin (UTA), conventional 1 Ah cells of economic grade have been constructed with both Nuvvon’s stable polymer electrolyte (SPE) or typical liquid electrolyte. The cell containing the liquid electrolyte exploded immediately, whereas neither of Nuvvon’s SPE cells, the Graphite-NMC811 nor the Lithium-NMC9, ignited.
Nuvvon’s stable polymer electrolyte is a pure polymer system that doesn’t include any sulfide or oxide nanoparticles. It has room-temperature ionic conductivity of better than 1 mS/cm at 25° C. It allows skinny format for separators (?20 µm) and is used because the catholyte, anolyte and separator. It’s made out of low-cost uncooked supplies which might be simple to obtain, and the cells could be made utilizing present lithium-ion processes, in response to the corporate.
The know-how is designed for functions resembling EVs, moveable electronics, aerospace and unmanned aerial automobile (UAVs).
“Battery security is a key concern for our companions and prospects, and we’re delighted to show our proprietary know-how’s security traits via impartial testing, paving the way in which for quicker commercialization of our know-how,” stated Jonathan Lex, Chief Working Officer at Nuvvon.
