Sicona Battery Technologies has won a significant boost from the Australian Renewable Energy Agency (ARENA) with a $45 million grant to develop a commercial-scale silicon-carbon battery anode plant in Wollongong’s Illawarra region. This funding supports Sicona’s transition from prototype development to manufacturing, with plans to produce up to 230 tonnes of its proprietary silicon-carbon anode material annually for supplier qualification and commercial sales.
The silicon-carbon composite, branded as SiCx, is designed for integration with existing lithium-ion battery manufacturing lines. This compatibility offers Sicona a streamlined route to securing customer contracts and entering global supply chains. The material reportedly increases energy density by more than 20% and enables charging speeds over 40% faster than traditional graphite anodes, leveraging silicon’s higher lithium storage capacity while managing its tendency to expand during charge cycles.
Sicona has formalized an exclusivity agreement with BlueScope Steel to explore situating the new production facility within BlueScope’s Port Kembla precinct, further strengthening local industrial collaboration. The Wollongong plant is expected to create approximately 36 skilled manufacturing positions, contributing to Australia’s efforts to establish sovereign battery materials capabilities ahead of expanding international demand.
ARENA’s CEO noted that independent testing has validated Sicona’s technology, which is already under evaluation by leading battery and electric vehicle manufacturers worldwide. Beyond electric vehicles, Sicona targets growing markets such as AI data centers, robotics, defense, and power tools, positioning SiCx as a versatile solution for diverse battery applications.
The $45 million grant complements previous strategic moves, including a licensing and investment partnership with India’s Himadri that included a follow-up funding injection of AU$17.5 million. Sicona also aims to scale production significantly, with plans for a larger facility capable of producing as much as 6,500 tonnes annually, with potential expansion to 26,500 tonnes.
The company’s founder emphasized that while electric vehicles remain a critical market, rapid growth is expected in sectors such as AI infrastructure, drones, and robotics. The Wollongong plant will serve as the first commercial validation of Sicona’s process, accelerating its entry into multiple industries while supporting Australia’s role in high-value battery material manufacturing.
