XING Mobility launches high-performance marine battery system

XING Mobility, the Taiwanese pioneer in immersion cooling battery technology, made its debut at SMM Hamburg with the IMMERSIO battery system, spotlighting its newest product, the marine-ready IMMERSIO CTP. Purpose-built for maritime electrification, IMMERSIO CTP combines the highest safety standards, sustained high performance and a compact footprint.

IMMERSIO CTP is built on XING’s patented immersion cooling architecture, in which every individual battery cell is fully submerged in a dielectric, electrically non-conductive coolant. Because heat is removed directly at the source, the system sustains high power output over time, actively suppresses thermal runaway, and prevents fire propagation between cells, marking a new safety benchmark for lithium-ion batteries at sea.

Key features include twice the energy density, with the cell-to-pack architecture delivering up to 2x the energy density of conventional marine batteries, freeing up space and weight for cargo, passengers or extended range; continuous 3C power, built for high-demand cycles and providing the high-rate discharge and rapid charging performance required by fast-transit vessels; flexible scaling by hull size, allowing the system to be easily scaled to match different hull dimensions and reduce engineering complexity for electric vessel development; and active fire safety, with immersion-cooled cells actively suppressing thermal runaway and preventing cell-to-cell propagation.

Together, high energy density, continuous power delivery and best-in-class fire safety position IMMERSIO CTP as a forward-looking foundation for zero-emission shipping.

XING Mobility’s IMMERSIO battery systems are already powering vessels on the water. The zero-emission Porrima P111 was launched in Taiwan equipped with an IMMERSIO battery system and has demonstrated reliable performance in open-ocean conditions. An IMMERSIO system has also been integrated into the newest vessel from Austrian electric-boat specialist Smart IQ, with commissioning and system-integration testing successfully completed in late April 2026.

XING Mobility is a global leader in immersion-cooled high-voltage battery systems. Starting with the development of Taiwan’s first electric supercar, MISS R, the company built core capabilities in peak instantaneous power output, high-frequency dynamic load stability and precision power control under extreme conditions. In 2024, XING Mobility established the world’s first mass-production facility for immersion-cooled battery systems and introduced IMMERSIO Matrix, a Unified Immersion Battery Architecture in which cooling, structure, safety and control are engineered as a single integrated system. The platform has since been extended across commercial vehicles, agricultural machinery, marine applications, energy storage and AI data centre infrastructure.
