Xing Mobility presents immersion-cooled batteries for ships
Xing Mobility is introducing two immersion-cooled battery systems designed specifically for maritime use. The modular Immersio XM25 solution can be adapted to various ship types, while the Immersio CTP is intended to offer exceptionally high energy density in a compact space thanks to its Cell-to-Pack architecture.
Xing Mobility plans to introduce the two systems adapted for maritime use at SMM 2026 in Hamburg. The exhibition — SMM stands for Shipbuilding, Machinery and Marine — takes place from September 1 to 4 in this Hanseatic city. The manufacturer describes both the Immersio XM25 and the Immersio CTP as next-generation battery systems developed specifically for the demands of marine environments. It adds that “both systems rely on the company’s patented immersion cooling technology, in which each individual battery cell is completely surrounded by an electrically non-conductive coolant.”
The background is that Xing Mobility is essentially a Taiwanese developer of immersion cooling technology for batteries. In immersion or submersion cooling technology, the battery cells are completely surrounded by coolant. More commonly used are cooling plates or channels that only touch one or two sides of a battery cell — heat transfer occurs over a much smaller surface area compared to immersion cooling. This approach is intended to efficiently dissipate heat and prevent thermal runaway within individual cells as well as fire spread throughout the entire battery pack.
In July 2022, Xing already launched the similarly named Immersio XM25 solution – though it was focused on heavy commercial vehicles. Three years earlier, at the IAA at that time, a first Cell-to-Pack battery solution (“Immersio CTP”) was also introduced, which is suitable for electric vehicles as well. At the Paris auto show in the fall of 2024, the Taiwanese company presented a Cell-to-Chassis solution. And at IAA Mobility 2025, they unveiled a CTP platform specifically for sports cars.
Against this backdrop, Xing Mobility describes the Immersio series as a flexible packaging concept that can be adapted to “the specific requirements of various vehicle types such as sedans, SUVs, sports cars, commercial vehicles, and more.” The packs are manufactured in a production facility opened in Taiwan since 2024.
The latest batteries in the Immersio family announced for SMM 2026 are designed for use on ships, with Xing Mobility only providing a rough overview of the batteries’ features without mentioning any performance data. The XM25 system is said to be able to adapt to different ship types thanks to its modular design, while the CTP system, via its Cell-to-Pack architecture, “reaches double the energy density of conventional ship batteries” and supports continuous 3C discharge, according to the company. Both systems are also said to offer sustained high performance, improve fire safety, and reduce space requirements on board.
