13 May Ampcera and Xponential Battery Materials (XBM) sign MoU to Develop a Sustainable Sulfur-Solid-State Battery

Ampcera Inc. International Battery Company (“Ampcera”) and Xponential Battery Materials (“XBM”) have signed a MoU to collaborate on the production of a NextGen sustainable, high-energy density, low weight, and cost-effective Sulfur (“S”) Solid-State Battery (S-SSB) for EVs.

Global Surge in Demand

The demand for affordable and sustainable, eMobility battery solutions presents a massive opportunity for new Sulfur cathode and Solid-State electrolyte technologies in the global EV/3C battery industries. This collaboration between Ampcera and XBM establishes a novel Li-S-SS and Na-S-SS battery development partnership that aims to leverage both company’s chemistries related Li-S/Na-S and Solid-State electrode manufacturing know-how to help OEMs accelerate commercial scale Li-S/Na-S-SS cell production in the US. “Ampcera is now working closely with XBM to further develop and produce a collaborative Sulfur+Solid State battery materials platform offering”, says Sumin Zhu, PhD, CEO of Ampcera. 

The battery chemistry in a Li-S/Na-S Solid-State battery system is quite unique. Different from NMC, LFP, or graphite-based EV Li-ion batteries (LIBs), in which the lithium ions intercalate into accessible space, Li-S-SSB is a conversion system. The cathode active material, sulfur as S8 covalently bonds with Li or Na ions through a series of reactions to create Li/Na2S, two Li/Na ions for each sulfur atom, creating some very promising SS battery performance opportunities.

Turning Industrial Waste Byproducts into Sustainable Sulfur Cathode Battery Materials

XBM takes abundant waste byproducts from petroleum (sulfur) and paper processing (lignin/tannin) industries to serve as a critical domestic EV battery material supply chain feedstock. According to Phil Roberts, XBM’s CEO, “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. We are very excited to be working with Ampcera as a leading Solid-State materials platform partner”. 

Ampcera is a U.S. based company focused on solid-state battery technology, specifically developing advanced solid-state electrolyte materials and scalable manufacturing processes. Their mission is to revolutionize energy storage by creating the foundation for next-generation lithium batteries, with a focus on applications like electric vehicles, consumer electronics, and defense systems. Ampcera’s technology centers around IP-protected sulfide-based solid electrolytes, which offer superior ionic conductivity, enabling fast charging and improved performance. www.ampcera.com

XBM is a pioneer in the 21st Century sustainable eMobility battery transition, seeking to address environmental, domestic supply chain, and mass production cost concerns. By leveraging the vast potential of abundant paper processing biomass materials (tannin/lignin) and petroleum industrial byproducts (sulfur), XBM is scaling up into commercial scale CarbonX Sulfur cathode material production – setting new global standards for next generation sustainable battery materials. www.xbmusa.com
