As the adoption of electric vehicles (EVs) progresses toward the realization of a decarbonized society, conventional lithium-ion batteries still face challenges such as resource constraints, degradation, and low recycling efficiency. These issues remain significant barriers to the establishment of a truly sustainable mobility society.
We are addressing these challenges through innovative material technologies.
We have successfully developed Ceramic battery centered on a new type of dielectric material called a “phase-change dielectric.”

Phase-change dielectrics exhibit a unique property where their dielectric constant changes in stages in response to electric fields or temperature, enabling them to achieve high energy storage performance and responsiveness not seen in conventional dielectric materials. This property provides the following advantages:
Ceramic batterie based on this phase-change dielectric material will not only become the new standard for EV applications, but also have potential applications in smartphones, wearable devices, and distributed power sources. With its superior charge/discharge characteristics, safety, and recyclability, this technology is expected to play a central role in next-generation power sources across a wide range of applications.

We are continuing our challenges to fundamentally redefine battery technology by leveraging our new material technology, phase-change dielectric. Toward an era where energy is stored in structure—we are taking the first step toward the next-generation energy society.
