Ampcera, a US-based developer of solid electrolyte materials and battery technology and Xponential Battery Materials (XBM), have signed an agreement to collaborate on the production of a high-energy density, low weight and cost-effective sulfur solid-state battery for EVs.

The collaboration establishes a lithium and sodium solid-state battery development partnership that aims to leverage both companies’ chemistries and electrode manufacturing know-how to help OEMs accelerate commercial scale solid-state cell production in the US.

Unlike lithium-ion batteries, in which the lithium ions intercalate into accessible space, a sulfur solid-state battery is a conversion system, in which the cathode active material covalently bonds with lithium or sodium ions through a series of reactions to create Li/Na2S, two lithium or sodium ions for each sulfur atom. This creates promising performance opportunities, according to the companies.

XBM takes waste byproducts from the petroleum (sulfur) and paper processing (lignin/tannin) industries to serve as a feedstock for the US EV battery material supply chain.

“Our CarbonX Li-S cathode material is the most sustainable EV battery cathode material with nearly 2x the capacity compared to other LIB cathode materials, at roughly half the cost of competing EV LIB cathode materials,” said Phil Roberts, XBM’s CEO.

“Ampcera is now working closely with XBM to further develop and produce a collaborative Sulfur+Solid State battery materials platform offering,” said Sumin Zhu, CEO of Ampcera.
