RNS Number : 1132E  Gelion PLC  21 October 2025

 

21 October 2025

Gelion plc
("Gelion", the "Company" or the "Group")

TDK and Gelion Establish Full Collaboration Agreement

 

To advance Sulfur battery technology anticipated to be transformational for
the industry

 

Gelion plc (AIM: GELN), 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."

Glossary

 Ah                      Ampere hours. A measure of capacity stored in the cell. The larger the number
                         the higher the capacity.
 mAh/g(S)                The unit mAh/g(S) stands for milliampere-hours per gram of Sulfur (with S
                         indicating "Sulfur"). It is a measure quantifying how many electrons (in mAh)
                         can be stored per gram of Sulfur.
 CAM                     Cathode active material
 Energy density (Wh/kg)  The ratio of energy stored per unit weight i.e. Watt-hours per kilogram. The
                         higher the number the lighter the battery.
 Pouch cell              An industry standard format of a battery which comprises a flat pouch-shaped
                         design with a multi-layered laminate structure.
 Cycle life              The number of full charge and discharge cycles a battery can complete before
                         its capacity falls below a specified level, typically 80% of the original
                         capacity. Higher cycle life indicates longer-lasting performance.
