At the signing table by the the Taihu Lake Bay in Yixing, the big cylinder battery project with 5.5 billion yuan investment was completed, and the gears of the new energy industry chain in the Yangtze River Delta were precisely engaged again. The landing of the Lanjing New Energy Full Pole Ear Large Cylinder Production Base in Wuxi has added a key weight to the technological competition of China's power battery track.

In the first half of 2026, the total shipment of large cylindrical batteries in China was 820 million units, a year-on-year increase of 114.3%. The proportion of full pole lithium iron phosphate large cylinders has reached 61%, and the window for industry scale and volume expansion has been fully opened. As the earliest technology-based enterprise in China to achieve stable mass production of full pole ear cylindrical batteries, Lanjing's 20GWh production base will directly fill the core production capacity gap of the full-length triangular cylindrical race track.

After the project is implemented, it will link upstream and downstream links such as high nickel and low cobalt positive electrodes, silicon carbon negative electrodes, high-voltage separators, and wide temperature range electrolytes, driving technological iteration throughout the entire chain. The mature precision manufacturing cluster of power batteries in Wuxi can also significantly shorten the cycle from equipment debugging to mass production ramp up for the new base.

In 2026, the delivery volume of new energy vehicle models equipped with large cylindrical batteries in China surged by 217% year-on-year, with 83% of the production capacity coming from the Yangtze River Delta cluster. This project landing is not an isolated capacity expansion, but a deep collaborative upgrade of the full pole ear large cylindrical industrial chain in the Yangtze River Delta.
