XING Mobility Debuts Immersion-Cooled Marine Battery System at SMM Hamburg
Summary
Taiwanese battery pioneer XING Mobility launched its marine-ready IMMERSIO CTP at SMM Hamburg, an immersion-cooled pack claiming twice the energy density of conventional marine batteries. The system targets zero-emission shipping with continuous 3C power, active thermal-runaway suppression, and scalable capacity for different hull sizes.
SMM Hamburg: XING Mobility Launches High-Performance Marine Battery System
HAMBURG, Germany, Sept. 02, 2026 (GLOBE NEWSWIRE) — XING Mobility, the Taiwanese pioneer in immersion cooling battery technology, makes 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: Engineered for the Realities of Life at Sea
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, a new safety benchmark for lithium-ion batteries at sea.
- Twice the Energy Density: The IMMERSIO™ CTP’s cell-to-pack architecture delivers 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, providing the high-rate discharge and rapid charging performance required by fast-transit vessels.
- Flexible Scaling by Hull Size: IMMERSIO™ CTP’s size and capacity can be easily scaled to match different hull dimensions, reducing engineering complexity for electric vessel development.
- Active Fire Safety: Immersion-cooled cells actively suppress thermal runaway and prevent cell-to-cell propagation, setting a new safety standard for batteries at sea.
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.
Proven Reliability: From Taiwan to Austrian Waters
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.
