Proven LFP chemistry meets a circular-ready battery pack architecture.

Thanks to its high cycle life, LFP is an established cell chemistry for electric boats, sailing yachts, and outboard motors. Neomium’s patented mcc©-process does not alter the chemistry but instead focuses on the battery pack’s contact system and design.

The architecture of every mcc-battery pack is essentially based on a central circuit board. This design enables a boat battery to be monitored down to the individual cell level. For different power ratings and propulsion concepts, essentially only the circuit board needs to be adapted to the respective cell layout. The magnetic contact system, the mcc©-BMS, and the central control computer Xenon form a common technology platform that is finalized and individually tailored to the specific application.

The Xenon connected Cockpit-App presents the collected information clearly on a tablet or other mobile device. This gives the boat owner insight into the boat battery and parts of the electric powertrain - including the current state of health (SoH) of the energy storage system.

From February 18, 2027, industrial batteries with a capacity exceeding 2 kWh will require a digital battery passport. Marine propulsion batteries fall into this category.

This introduces new documentation and verification obligations for manufacturers: composition, condition data, spare parts, disassembly steps, and the battery’s current status within the circular economy must be documented transparently and kept up to date. MCC does not relieve manufacturers of these regulatory obligations. However, individual cell monitoring provides a detailed data basis, while the standardized, weld-free and bond-free design makes the disassembly process clearly documentable, reproducible, and practical to carry out.

At the end of their service life in a marine application, the cells can be removed from the battery enclosure without damage, assessed individually, and directed toward continued use, a new application, or recycling according to their condition. This turns legally required documentation into a technically feasible circular process. Corrosion protection, sealing, impact and vibration resistance, and marine certifications remain separate requirements to be addressed in each development project.

mcc© provides manufacturers and boat owners with a new foundation for adaptable, transparent, and circular marine battery systems.
