Sunwoda Electronics promoted its latest vertically stackable and winding type of battery cells at All Energy Australia 2025
The company also showcased its liquid-cooled ESS for the Australian market
This storage solution is currently commercially available in Australia
Sunwoda Electronics Co., Ltd., a China-based provider of lithium-ion-based storage solutions, unveiled its new battery energy storage system (BESS) and cells at All Energy Australia 2025.
Tailored for the Australian market, the company highlights performance, reliability, and ease of integration into BESS as the key features of these products. The displayed cell, which is designed for vertically stacked storage architecture, is rated for up to 684 Ah of capacity. The company states that these cells, stacked in a cabinet or container, provide a ‘high’ energy density in space-constrained applications. It also supports utility high-capacity BESS applications.
The 588 Ah battery cell, also on display, is of the winding type that stacks and tightly rolls the sheets of anode, cathode, and separator together. Unlike the cabinet-stacked cells mentioned above, this design provides uniform paths of charging/discharging current, reduces internal resistance due to the uniform alignment of electrodes and consistent pressure from multiple layers, and offers higher mechanical stability. These attributes help maintain stability over multiple cycles of charging/discharging with consistent energy efficiency, making the cell suitable for applications that require frequent charging/discharging.
Sunwoda also displayed its Liquid Cooling ESS, which the company says is designed for flexibility and resilience. Equipped with cells of the winding type, it is rated for a maximum charging or discharging of 3 MWh. This storage solution is compatible with a DC-coupled BESS configuration, and its modular design offers flexibility to project developers in transportation and installation. Safety features, like a fire protection system at multiple levels, ‘precise’ measurement and control of operational temperature and humidity, address diverse environmental stressors spanning Australia’s arid fields to humid coastal regions.
Sunwoda’s energy storage systems are currently commercially available in Australia.
