Las Vegas (ots/PRNewswire) - At RE+25, Sunwoda (stock code: 300207), a global provider of all-scenario energy storage solutions, unveiled two new, highly innovative, large-capacity energy storage cells: the 684 Ah and 588 Ah models. These flagship innovations further strengthen Sunwoda's position as a leader in advanced battery technologies tailored to the evolving needs of the global energy storage market. Launch of Sunwoda 684 Ah and 588 Ah Cells at RE+25: "The launch of the 684 Ah and 588 Ah energy storage cells represents a significant milestone in Sunwoda's continuous innovation and development efforts in large-capacity energy storage technologies," said Dr. Sam Chen, Managing Director of BESS BU at Sunwoda. "The company is committed to building a mature and reliable product portfolio that covers diverse application scenarios and provides our customers with higher lifecycle value and a better return on investment." Developed with advanced stacking technology, the 684 Ah cell achieves an energy density of over 440 Wh/L and incorporates thermal-electrical separation with a three-dimensional heat dissipation structure to ensure safe and stable operation. It is designed for a service life of over 20 years and can be flexibly combined with 10-foot, 20-foot, and 30-foot containers. The high-density design reduces container consumption by 27%, shortens assembly time, lowers costs, and reduces the Levelized Cost of Energy (LCOE) by 8%, improving deployment speed and overall economic efficiency. The product is scheduled to enter mass production in Q4 2025 to meet market demand.

The 588 Ah cell utilizes proven winding technology enhanced by a low-lithium loss innovation. It extends cycle life to 10,000 cycles at 70% SOH and enables reliable operation for more than 20 years. With 96.5% energy efficiency, advanced electrolyte safety, and a directional venting design, it ensures long-term stability and cost-effectiveness.
