Xing Mobility introduces immersion-cooled batteries for ships

Xing Mobility is launching two immersion-cooled battery systems specifically for maritime applications. The modular Immersio XM25 solution is adaptable to different ship types, while the Immersio CTP, with its cell-to-pack architecture, is designed to offer particularly high energy density in a compact space.
Xing Mobility will present two battery systems for maritime applications at SMM 2026, an international maritime trade fair taking place in Hamburg, Germany, from 1 to 4 September. The manufacturer describes the Immersio XM25 and Immersio CTP as next-generation battery systems developed specifically for marine environments. As the company states: “Both systems are based on our patented immersion cooling technology, in which every single battery cell is fully surrounded by an electrically non-conductive cooling fluid.”
Xing Mobility is, at its core, a Taiwanese developer of immersion cooling technology for batteries. In immersion or submersion cooling, the battery cells are completely flooded with coolant. Typically, cooling plates or channels only touch one or two sides of a battery cell, meaning heat transfer occurs over a significantly smaller surface area than with immersion cooling. This technology is designed to dissipate heat efficiently and prevent thermal runaway in individual cells, as well as the spread of fire throughout the entire pack.
In July 2022, Xing Mobility introduced the Immersio XM25, initially targeting heavy-duty commercial vehicles. In August 2023, the company followed with its first cell-to-pack battery solution, the Immersio CTP, which is also suitable for electric cars. At the Paris Motor Show in autumn 2024, the Taiwanese company presented a cell-to-chassis solution. Most recently, at IAA Mobility 2025, Xing Mobility introduced a CTP battery specifically designed for sports cars.
Against this backdrop, Xing Mobility describes the Immersio series as a flexible battery pack concept that can be adapted to the “specific requirements of various vehicle types, such as saloons, SUVs, sports cars, commercial vehicles, and more.” The company manufactures the packs at its production facility in Taiwan, which opened in 2024.
Xing Mobility has now adapted the latest batteries in the Immersio family for ships and will present them at SMM 2026. However, the company has provided only broad details about their properties and no performance data. The modular design of the XM25 allows it to accommodate different vessel types, while the CTP system uses a cell-to-pack architecture that “achieves double the energy density of conventional marine batteries” and supports continuous 3C discharge. Xing Mobility designed both systems to deliver consistently high performance, improve fire safety and reduce onboard space requirements.
