Sunwoda has announced the achievement of a major manufacturing and delivery milestone, with its one-millionth 684Ah stacked energy storage cell rolling off the production line for delivery, marking a significant step forward in the large-scale commercialization of high-capacity energy storage cells.
Since the 684Ah stacked cell entered mass production in September, the company has reached a production volume of one million units within just three months, signalling that large-capacity stacked energy storage cells have entered a stable and mature phase of scalable manufacturing.
The latest 684Ah cell adopts advanced flash stacking battery technology, achieving an energy density of over 440 Wh/L. Since its launch, the product has demonstrated Sunwoda’s technical strength in large-capacity energy storage cells, supporting industry progress toward higher safety, greater efficiency and enhanced lifecycle value at the system level.
The delivery of the one-millionth cell further reinforces the company’s leading position in energy storage cells and provides a solid foundation for long-term, large-scale deployment across global markets. Through early strategic investment in stacked-cell manufacturing processes, Sunwoda has established an end-to-end manufacturing system, from product design and process validation to large-scale production, ensuring consistently high uniformity, reliability and efficiency.
