The X-SEPA does much more than a typical separator - it is a crucial next- generation component that can improve reliability, performance, and lifespan. Whether high reliability for public buses or high power for air mobility, we can finely control the structure and physical properties of each of the X-SEPA's multiple layers to meet performance targets for wide-ranging applications.
The X-SEPA also extends battery life, minimizing the footprint of each battery and unlocking new potential for circular use.
We are able to customize an exceptional separator that meets your needs.

HOW IT WORKS
WHAT IS A SEPARATOR ?
A porous film separating the cathode and anode (positive and negative electrodes) that ions pass through during charging and discharging.
WHY IS IT IMPORTANT ?
Short circuiting and fires occur when separator function is lost, and the cathode and anode connect. The separator is therefore crucial to maintaining battery safety.
DR. KANAMURA'S DISCOVERY
3DOM CTO Dr. Kiyoshi Kanamura saw the separator as the key to unlocking next-generation battery technologies and invented the 3DOM separator at Tokyo Metropolitan University.
THE SEPARATOR IS THE SOLUTION
BALANCE OF ENERGY DENSITY AND RELIABILITY
High energy density materials are required to extend electric vehicle range, but higher energy density accelerates uneven chemical reactions that lead to short circuiting, stunting battery reliability and hindering commercialization.Next-generation applications demand a battery that achieves both high energy density and reliability.
3DOM batteries push technological boundaries, enabling us to redefine the battery as a vital element of social infrastructure in a sustainable society.
3DOM’s innovative lithium-ion batteries offer superior reliability, energy density, and lifespan made possible by the 3DOM separator, meeting the needs of growing mobility and energy storage markets.
