Sunwoda Launches Revolutionary Energy Storage Solutions

At the recent RE+ 25 event held in Las Vegas, Sunwoda, a prominent player in the energy storage sector, introduced two innovative large-capacity energy storage cells: the 684Ah and 588Ah models. This unveiling marks a pivotal moment for the company, which has consistently sought to lead advancements in battery technology.

Dr. Sam Chen, the General Manager of the Battery Energy Storage System (BESS) Business Unit, articulated the significance of these launches: "The introduction of the 684Ah and 588Ah energy storage cells is a testament to our relentless innovation in large-capacity technologies. We are dedicated to offering a robust and reliable product range that caters to various applications, enhancing lifecycle value and investment returns for our customers."

Features of the 684Ah Model

The 684Ah energy storage cell stands out due to its advanced stacking technique, boasting an impressive energy density of over 440Wh/L. This cell is not only designed for optimal performance but also incorporates a thermal-electric separation system combined with a three-dimensional heat dissipation structure, ensuring safe and stable operation. With a service life exceeding 20 years, it can be easily integrated into various container sizes: 10ft, 20ft, and 30ft. These design features enable a remarkable 27% reduction in container use, speeds up assembly processes, and drives down both costs and Levelized Cost of Energy (LCOE) by 8%. Mass production of this model is anticipated to commence in the fourth quarter of 2025, ensuring adequate supply for the growing market.

The 588Ah Variant

On the other hand, the 588Ah cell leverages well-established winding technology, augmented by innovations that minimize lithium loss. This cutting-edge cell promises a cycle life of up to 10,000 cycles at 70% State of Health (SOH), along with over 20 years of dependable operation. With an impressive 96.5% energy efficiency and enhanced electrolyte safety, this cell is built for long-term stability and economic viability. Its directional venting design further contributes to its reliability.
