Sicona’s proprietary SiCx® silicon-carbon composite anode technology combines silicon and carbon to deliver up to 50% higher energy density compared to graphite-only cells. The manufacturing process uses abundant silicon metal instead of silane gas, integrates seamlessly into existing battery production lines and next-generation dry electrode systems, reduces charging times by over 40%, and addresses silicon anode volume expansion through innovative material design.
SiCx® silicon-carbon anode materials featuring up to 50% increased energy density, over 40% faster charging, compatibility with existing battery manufacturing processes and next-generation dry electrode technology, designed for electric vehicles and energy storage applications.
In 2025, Sicona announced plans to build its first commercial manufacturing facility in the southeastern United States with an initial capacity of 6,700 tonnes per annum of silicon-carbon anode material, expanding to 26,500 tonnes by the 2030s. The project includes a partnership with Bechtel for front-end engineering design, product sampling with potential U.S. customers, and ongoing material supply qualification throughout 2025.
Sicona Battery Technologies closed its Series A financing led by Himadri Speciality Chemical Ltd, with participation from Artesian, Electrification & Decarbonization AIE LP (Waratah Capital), Riverstone Ventures, Chaos Ventures, Investible Climate Tech Fund LP, and Club Investible.
