Talga Group Wins Three US Patents, Advancing Battery Anode Tech Amid China Export Controls

Talga Group Secures US Patents for Graphite Battery Anode Innovations

Talga Group Ltd, a leading battery materials and technology company, has been granted three new patents by the United States Patent and Trademark Office for its proprietary graphite-based technologies. These patents bolster Talga’s intellectual property portfolio for advanced battery anode materials and processes, with exclusive rights extending through 2042. The timing of these awards is notable, arriving just as China announces upcoming export controls on lithium-ion battery graphite materials, technologies, and production equipment—measures set to take effect on November 8, 2025. 

Details of Talga’s Patented Technologies

The newly issued patents cover several proprietary innovations:

• Tanode-C: Talga’s flagship graphite battery anode material, developed in Europe and the UK, now has patent protection in the US, securing Talga’s exclusive rights to both the material and its production technology.
• : A patent for a method of producing oblate spheroid graphite particles enables faster battery charging, higher energy density, and enhanced low-temperature reliability—key advantages for next-generation batteries.
• Hydrometallurgical Purification Process: This patented process allows Talga to produce battery-grade graphite from natural or recycled sources, reducing reliance on China-based equipment or technology.
• Graphene Production Method: Utilizing a chemical linker, Talga’s graphene method supports safer, more cost-effective metal coatings and expands application from battery foils to automotive, infrastructure, and aerospace industries.

Talga’s intellectual property is protected globally under the Madrid Protocol and other international IP frameworks, further supporting its expansion in Western markets.

China’s Export Controls Heighten Supply Chain Security Concerns

China’s Ministry of Commerce and General Administration of Customs recently announced sweeping export controls on graphite-related battery materials and production equipment, effective November 8, 2025. These restrictions include not only natural graphite, but also artificial (synthetic) graphite anode materials, blends, and key manufacturing technologies. Exporters will be required to secure licenses, a move designed to safeguard national interests and reinforce China’s dominant position—supplying roughly 99% of the world’s battery-ready graphite and anode technologies.

Most Western battery manufacturers rely on Chinese technology and equipment, except for vertically integrated firms like Talga. As a result, these new controls are expected to disrupt global battery supply chains, prompting Western countries to seek alternative sources and secure domestic capabilities.

Industry Reaction and Strategic Impact

Industry observers and investors have responded positively to Talga Group’s patent wins, noting the strengthened position of the company in the US and European battery markets as supply chain security moves to the forefront of industry priorities. Technology analysts cite Talga’s vertical integration and independence from Chinese technology as critical advantages, especially in light of the emerging “Graphite Crisis.”

Mark Thompson, Talga Group’s Managing Director, emphasized the significance of these developments:

“These US patents validate our innovation and strength of graphite material technology in the world’s most dynamic market. As industrialised society faces a ‘Graphite Crisis’, our vertical integration and technology offer a unique 100% controlled alternative for global customers seeking supply chain security and performance excellence.”

Talga’s share price has reflected this optimism, with a notable increase following the patent announcement. The company’s expanded presence in the US, coupled with its proprietary technologies, positions it as a key player in the Western push for secure, high-performance battery materials.

Outlook: Western Battery Sector Poised for Change

Talga Group’s latest patent awards are expected to accelerate the development of secure supply chains for energy storage, defense, and mobility sectors across the US and Europe. With China’s export controls set to reshape global sourcing, Talga’s innovations and independence offer Western manufacturers a critical alternative.

As demand for advanced battery materials grows, Talga’s technology portfolio and strategic timing may prove pivotal in driving the next phase of energy storage and electrification across key regions.
