Estimated reading time: 2 minutes

Gelion plc, the global energy storage innovator, is delighted, further to its announcement on 16 October 2025, to announce that the Tier One battery manufacturer with whom it has signed a full collaboration agreement is TDK Corporation (TDK), the Japan headquartered global electronics and battery manufacturer with over 100,000 employees worldwide, operating major manufacturing facilities across Asia, Europe, and the Americas, serving industries such as automotive, industrial, and consumer technology.

TDK and Gelion have agreed to collaborate to develop battery technologies which utilise Gelion's Sulfur battery Cathode Active Material (CAM) which is in turn being advanced with the support of a multi-year collaboration partnership between Gelion and the Max Planck Institute of Colloids and Interfaces (MPI).

The multi-year collaboration will:

• Facilitate the development of large format commercial pouch cell prototypes (type of rechargeable batteries), 
• Evaluate how batteries incorporating the CAM perform across various applications to refine practical product fit and helping to de-risk the development of high-power, long-life battery cells,
• Enable integration into TDK prototype production lines,
• Deliver partner revenue from CAM supply,
• Support Gelion's strategic focus on advancing its Sulfur battery platform from prototype to commercial readiness for next generation mobility, aviation, and energy storage markets.

Gelion will now commence production of laboratory scale materials with pouch cell prototyping by TDK at its plant in Nagano, Japan. The main objective will be to progress to prototype lines for qualification of battery cell manufacturing within the next 12 months.

Dr. Yasushi Enokido, the General Manager of the Advanced Products Development Center in TDK, said "We are delighted to collaborate with Gelion and the Max Planck Institute of Colloids and Interfaces to advance next-generation battery technologies. We aim to accelerate the development of practical, high-performance solutions. This partnership reflects our focus on driving innovation and contributing to a more sustainable future."

John Wood, CEO of Gelion, commented:  "It is a great honour to be able to work alongside TDK toward realising the exciting potential of this breakthrough battery technology. TDK is one of the world's great innovation centres and lives its brand identity "In Everything, Better". In Gelion's path, alongside MPI toward positive transformation, there is no better partnership we could form than with TDK to lead the way."
