On October 24, 2025, Gelion (AIM code: GELN), a global energy storage innovation company, announced that it has signed a comprehensive cooperation agreement with TDK Corporation (TDK), a leading Japanese electronics and battery manufacturer.
technical cooperation
The aim of this collaboration is to develop battery technology using Gelion sulfur battery cathode active materials (CAM), which has benefited from years of collaboration between Gelion and the Max Planck Institute for Colloids and Interfaces (MPI). The cooperation includes:
Develop prototypes of large-scale commercial pouch batteries (rechargeable batteries);
Evaluate the performance of CAM technology in different application scenarios and optimize product adaptability;
Reduce the development risk of high-power long-life battery cells;
Integrate with TDK prototype production line;
Provide benefits to both parties through CAM supply.
Project Updates
Gelion will initiate the production of laboratory scale materials and TDK will manufacture pouch battery prototypes at their Nagano factory in Japan. The goal is to advance to the prototype production line stage within the next 12 months and complete the qualification certification for battery cell manufacturing.
