Leclanché was pleased to participate in the WATTS UP 2026 Marine Battery Forum in Mallorca, where Tunji Adebusuyi, Technical Marine Manager at Leclanché, delivered a presentation on the latest developments in lithium-ion battery technology for maritime applications.

In his presentation titled “NMCA High-Capacity Cathodes for Marine Applications,” Tunji explored how advanced lithium-ion cell chemistries and innovative cell design can help address the evolving requirements of the marine sector. Modern marine propulsion systems increasingly demand battery solutions that deliver a careful balance of power capability, energy density, safety, and long lifecycle performance.

The presentation highlighted Leclanché’s ongoing work in developing high-nickel NMCA cathode materials, designed to improve energy density while maintaining strong cycling performance. Tunji also discussed how these cells can be integrated into Leclanché’s Marine Rack System (MRS-3) to create high-performance battery systems suitable for demanding maritime operations.

In addition to performance improvements, the session explored innovative approaches to battery manufacturing, including water-based electrode processing and PFAS-free material development, supporting the industry’s broader transition toward more sustainable and environmentally responsible battery technologies.

The technologies presented are particularly suited to applications such as hybrid and fully electric vessels, ferries requiring frequent charging cycles, peak shaving, and spinning reserve operations, where both high-power output and energy capacity are critical.

Industry forums such as WATTS UP provide valuable opportunities to exchange knowledge, share technical developments, and collaborate with partners working to accelerate the electrification of maritime transport.

Leclanché remains committed to advancing battery innovation to support the transition toward cleaner, more efficient marine propulsion systems.
