Xponential Battery Materials (XBM USA LLC)
Volta MemberVFAbout
Xponential Battery Materials develops and manufactures lithium-sulfur cathode active material from domestic industrial byproducts such as lignin, tannin and sulfur.
Its flagship product, CarbonX, is meant to give US and EU battery makers a key material for lithium-sulfur batteries approaching 500 Wh/kg, doubling today's best lithium-ion cathode chemistry while reducing battery cost and weight. It supplies cell makers rather than making cells itself. It is also developing a silicon-carbon anode material and is ramping pilot-scale production of both in the US.
XBM USA LLC was formed in 2020 and is based in Los Angeles, California. It is led by CEO and co-founder Phillip Roberts and CTO Dr. JB Yang, a former Argonne National Laboratory staff scientist.
