Gelion, a UK-based energy storage innovator, has announced a collaboration with Japan’s TDK Corporation to advance sulphur battery technology.
This partnership aims to revolutionise sulphur battery technology using Gelion’s Sulphur Cathode Active Material (CAM), developed in collaboration with the Max Planck Institute of Colloids and Interfaces (MPI).
The multi-year agreement will focus on developing large-format commercial pouch cell prototypes, evaluating their performance across various applications to ensure high-power, long-life battery cells. It will also integrate Gelion’s CAM into TDK’s prototype production lines in Nagano, Japan, and generate revenue through CAM supply.
This collaboration supports Gelion’s goal of advancing its sulphur battery platform from prototype to commercial readiness for next-generation mobility, aviation and energy storage markets. Laboratory-scale material production has begun, with pouch cell prototyping underway, targeting qualification for battery cell manufacturing within 12 months.
Dr Yasushi Enokido, general manager of TDK’s Advanced Products Development Center, 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, added, “It is a great honour to be able to work alongside TDK toward realising the exciting potential of this breakthrough battery technology.”
