Sunwoda Unveils Groundbreaking Energy Storage Cells

At the recent RE+ 2025 event in Las Vegas, Sunwoda, a prominent player in the energy storage solutions sector, showcased two groundbreaking battery cells with capacities of 684 Ah and 588 Ah. These new products signify a significant leap forward in the company's ongoing innovation journey, solidifying its position as a leader in advanced battery technology designed to adapt to the evolving global energy storage market.

Dr. Sam Chen, CEO of Sunwoda's Battery Energy Storage System (BESS) division, expressed his enthusiasm for the launch, stating, "The introduction of 684 Ah and 588 Ah energy storage cells is a pivotal milestone in our innovation process. We are committed to assembling a sophisticated and reliable product portfolio that effectively addresses various application scenarios while providing our customers with enhanced lifecycle value and return on investment."

Advanced Features of the New Cells

The 684 Ah cell boasts an energy density exceeding 440 Wh/l and features integrated thermal-electric separation alongside a three-dimensional heat dissipation structure, ensuring safe and stable operational conditions. The cell is engineered for a long lifespan exceeding 20 years and can flexibly integrate with 10ft, 20ft, and 30ft containers. Its high-density design reduces container usage by 27%, accelerates installation time, and lowers the Levelized Cost of Electricity (LCOE) by 8%, boosting deployment speed and overall economic feasibility.

The 588 Ah cell utilizes proven winding technology enhanced with low lithium loss innovation, extending its lifespan to 10,000 cycles at 70% State of Health (SOH) while ensuring over 20 years of reliable operation. With an impressive energy efficiency of 96.5%, advanced electrolyte safety, and a directed venting design, this cell guarantees long-term stability and cost-effectiveness.

Sunwoda's Commitment to Sustainability

As a recognized global leader in new energy technologies, Sunwoda ranked among the top ten global energy storage cell suppliers in the first half of 2025. BloombergNEF acknowledged the company as a Level 1 manufacturer within the energy storage sector. The firm continues to expand its international manufacturing network, establishing production bases in countries like China, Thailand, and Hungary, ensuring localized, efficient, and reliable supply chain support for markets worldwide.

With the launch of the new 684 Ah and 588 Ah cells, Sunwoda reinforces its commitment to advancing large-scale energy storage solutions, promoting a transition towards a more sustainable energy future.
