From December 2nd to 5th, CALB took part prominently in Marintec China 2025, a leading maritime exhibition held in Shanghai. The company presented its full portfolio of marine battery energy storage solutions, underscoring both China's progress in battery technology and its strategic contribution to the worldwide shift toward sustainable shipping.

Building on strong R&D capabilities and a forward-looking strategy, CALB displayed core products and technologies tailored to meet real-world industry demands. The exhibition demonstrated the company’s multi-dimensional solution expertise, systematically highlighting a comprehensive competitive edge—from cell to system, and from technology to service.

Next-Generation Cells Set New Benchmarks in Lifespan

A key highlight was the second-generation 320Ah marine LFP battery cell. By combining full-lifecycle lithium replenishment technology with a high-efficiency LFP material system, it achieves a breakthrough cycle life of over 12,000 cycles. This offers more than a 20% improvement compared to mainstream products, substantially lowering vessel lifecycle operating costs and providing long-term value for shipowners.

High-Power Systems Meet Demands of Specialized Vessels

To address the needs of high-power vessels such as offshore service ships and tugs, CALB launched a high-power battery system capable of continuous 2C and peak 4C discharge rates. Through efficient coordination between its intelligent BMS and hybrid power systems, it ensures engines run within optimal efficiency ranges. This improves fuel economy, cuts emissions, and delivers reliable power for complex, intelligent green operations.

Integrated Full-Chain Solutions Create Added Value

Backed by leading cell technology and deeply integrated systems, CALB is dedicated to offering global partners a one-stop, full-chain portfolio—from cells and modules to complete battery systems and containerized power solutions. Its diverse product matrix and deep integration expertise enable the delivery of safe, economical, efficient, and flexible battery systems customized for various vessel types and operational profiles, positioning CALB as a full-cycle partner in shipping’s green transformation.

Looking ahead, CALB reaffirmed its commitment to open collaboration with industry partners worldwide. The company aims to continually advance marine battery technology toward higher safety, efficiency, longevity, and cost-effectiveness, working together with the international maritime community to steer toward a greener, smarter, and more sustainable future.
