From December 2nd to 5th, Marintec China 2025, the highly anticipated international maritime exhibition, was grandly held at the Shanghai New International Expo Center. CALB made a grand appearance with its full range of marine battery energy storage solutions, showcasing to the global maritime industry China’s leading strength and strategic vision in driving the green transformation of shipping through advanced battery technology.
Building on its continuously deepening R&D system and forward-looking strategic planning, CALB’s core products and technologies exhibited at the event closely address the practical needs of the industry. Through multi-dimensional solution capabilities, the company systematically demonstrated its comprehensive competitive advantages—from cells to systems, and from technology to service:
The highlight of the exhibition was the second-generation 320Ah marine battery cell. By innovatively integrating full-lifecycle lithium replenishment technology with a high-efficiency lithium iron phosphate (LFP) material system, it achieves an industry milestone of over 12,000 cycles—extending service life by more than 20% compared to mainstream products. This significantly reduces the vessel’s whole-lifecycle operating costs and creates enduring value for shipowners.
To meet the specific demands of high-power vessels such as offshore support vessels and tugboats, CALB launched a high-power battery system capable of continuous 2C and peak 4C rate discharge. Through efficient coordination between an intelligent BMS and hybrid power systems, it ensures that engines consistently operate within the optimal efficiency range, markedly improving fuel economy and reducing emissions. This provides strong and reliable power support for green and intelligent operations under complex working conditions.
Leveraging leading cell technology and deeply integrated system capabilities, CALB is committed to providing global shipping partners with a full-chain, one-stop solution—spanning cells, modules, battery systems, and containerized power solutions. Supported by a diverse product portfolio and deep system integration expertise, CALB delivers safe, reliable, cost-effective, and flexibly adaptable battery systems tailored to different vessel types and operational needs, serving as a full-cycle enabling partner for the green transformation of the shipping industry.
Looking ahead, CALB will continue to uphold an open and cooperative approach, working closely with partners across the global industrial chain. The company remains dedicated to advancing marine battery technology toward higher safety, greater efficiency, longer lifespan, and better economics—joining hands with the global maritime industry to sail toward a green, intelligent, and sustainable future.
