~Jointly developed with a Singapore-based startup company, unveiled at BATTERY JAPAN 2026~
SAKATA INX CORPORATION (Headquarters: Chuo-ku, Osaka City; Yoshiaki Ueno: Representative Director President & CEO; Securities code: 4633; hereinafter referred to as “SAKATA INX”) is pleased to announce that it has developed a next-generation thermal management material, “Thermorphous™ FX25 (development product) ” in collaboration with a Singapore-based startup company, Matwerkz Technologies Pte. Ltd. (hereinafter referred to as “Matwerkz Technologies”). This product will be unveiled for the first time at the “BATTERY JAPAN (International exhibition for Rechargeable Battery)” to be held at Tokyo Big Sight from March 17 (Tue) ~ 19 (Thu), 2026.
【Overview】
Thermorphous™ FX25 (development product) is a temperature-responsive thermal management material that is ideal for battery packs for EVs, electric mobility, and standby and uninterruptible power supply units. It exhibits high thermal conductivity at normal operating temperatures, and heat diffusion between battery cells can be expected to increase battery output performance and long life. On the other hand, at the temperature range where the cell’s thermal runaway occurs, the thermal conductivity will sharply drop, and it will exert a heat shielding function. This allows for an advanced safety design where a heat insulating shield would form around the affected cells thus preventing the spread of fire to adjacent cells. This unique performance within a single material enables the realization of both “safety and output performance,” which was previously difficult to achieve in the past. It also contributes to simplifying the structure within the battery pack and reducing total costs.
Since it comes in the form of a two-component liquid potting agent, it can easily conform to cylindrical, square, and pouch battery cell dimensions. By using molds, it is possible to be molded into three-dimensional shapes such as cell holders and sheets.
A major feature is its ability to fill gaps as small as 1mm or less, making it possible to handle complex three-dimensional structures.
The unique characteristics of Thermorphous™ FX25：
Two-component curing heat dissipation and thermal insulation potting agent
Thermal conductivity (room temperature): 1.0 W/m·K or higher
Thermal conductivity (during thermal runaway): 0.1 W/m·K or lower
Viscosity: 3.2Pa·s (25°C )

【Background of Joint Development】
In 2023, we invested in Matwerkz Technologies with the aim of streamlining energy storage and operation to realize a society where energy can be safely and securely used. Under the shared vision of both companies, we have been promoting technical collaboration in the field of thermal management. While lithium-ion batteries offer increased output and improved convenience, the number of fire incidents involving battery packs is unfortunately on the rise. The requirement for massive computational processing and extensive usage of high-performance devices due to the proliferation of AI would compound the need for effective thermal management. As thermal management is the foundation for a sustainable society, innovative technological development is essential. Our company actively tackles this key theme and continues to take on challenges to contribute to society. A joint evaluation with one major domestic company is currently underway, and we aim to mass-produce this product in 2027.
