XBM USA and SiCAM Technologies Collaborate to Advance Next-Generation Silicon-Sulfur Battery Technology

Collaboration pairs SiCAM's low-cost silicon-carbon anode material with XBM's sulfur cathode and cell technologies, to offer US battery OEMs an integrated silicon-sulfur (Si-S) battery platform.

LOS ANGELES, Oct. 8, 2026 /PRNewswire/ -- XBM USA LLC ("XBM") and SiCAM Technologies, Inc. ("SiCAM") today announced a technology collaboration to develop a Silicon-Sulfur (Si-S) very high-energy-density battery materials platform by coupling SiCAM's silicon-carbon (Si-C) anode material with XBM's lithium-sulfur (Li-S) cathode materials and advanced cell technologies.

Silicon-sulfur is amongst one of the most promising next-generation battery cathode and anode chemistry platforms, with substantially higher theoretical energy density than conventional li-ion batteries (LIBs). Silicon is the second-most-abundant element in the Earth's crust, sulfur is a U.S. petroleum-refining byproduct, and XBM's Li-S cathode is derived from lignin, an abundant U.S. paper pulping byproduct.

Asia, predominantly China, currently controls ~80–95% of the global battery cell and materials supply chain. U.S. battery manufacturers are seeking better, lower-cost, domestically sourced chemistries that reduce reliance on foreign materials. This shift creates opportunities for U.S. OEMs to leapfrog legacy technologies. Jon Shan, Chief Technology Officer of XBM USA, said, "Our near-term objective is to optimize our high-capacity Li-S cathode and SiCAM's Si-C anode in a first-of-its-kind silicon-sulfur battery platform, initially targeting high-energy-density, lightweight eMobility battery applications such as eVTOLs and drones."

SiCAM's proprietary silicon anode material and process are unique amongst all other Si-C anode products made today. Most other Si-C anode material developers use silane (silicon) in a CVD process to make their Si-C anode products. SiCAM uses chlorosilane (TCS) silicon in a fluidized-bed chemical vapor deposition (FB-CVD) process. This novel approach creates a true bonded silicon-composite primary structure, helping to reduce the 300% silicon swelling problems experienced during battery charge and discharge cycles.

On the cathode side, XBM's high-capacity Li-sulfur cathode targets improved sulfur utilization, cycle life and cell-level energy density using abundant industrial byproducts, such as sulfur and lignin. "This silicon-sulfur cell technology collaboration is the natural evolution of our company's US centric "Sustainable Battery" vision avoiding longstanding battery chemistries that are mined, more expensive, and foreign sourced and controlled" said Phillip Roberts, co-founder of SiCAM Technologies and XBM USA.
