GS Yuasa has confirmed that its space-qualified lithium-ion batteries were utilised in the launch of JAXA’s HTV-X1 transfer vehicle on 26 October 2025. This application marks one of over 250 space-vehicle missions supported by the company’s technology, which is selected for its energy density and stability in orbital environments.
The batteries are engineered to withstand extreme temperatures and deep cycling during orbital flight. GS Yuasa notes that the manufacturing principles used for these space-grade cells—including precise cell construction and materials control—also underpin the LIM series lithium-ion batteries supplied for industrial use across Europe.
These industrial applications include energy storage systems, robotics, automated guided vehicles (AGVs), and uninterruptible power supplies (UPS). Eiichiro Kato, Operations & Administration Director of GS Yuasa Battery Europe Ltd, commented:
“Supporting the HTV-X1 mission is a significant achievement for our engineers worldwide. Space is one of the most demanding environments imaginable, and seeing our technology operate under such conditions is a strong reflection of our capabilities. The knowledge gained from these programmes plays an important role in the development of the lithium-ion solutions we supply across Europe, helping ensure that our products deliver the same consistency and dependability in every application.”
The mission highlights the transfer of engineering insights from extreme-environment projects to ground-based infrastructure. For more information on GS Yuasa’s industrial and space-grade power solutions click here.
