Building on its success in mass-producing large-capacity battery cells, China’s EVE Energy has reached a new industry milestone. It said this week that the world’s first 100 MWh-class battery energy storage facility using 628 Ah ultra-large battery cells has entered operation.
The 200 MW/400 MWh Ruite New Energy Lingshou project features 80 Mr. Giant energy storage systems and 40 integrated converter cabins. Its cell design incorporates an innovative stacking process and high-toughness separators, enhancing safety while optimizing the levelized cost of storage (LCOS).
Mass production of these large-capacity cells began in December 2024, making EVE Energy the first manufacturer to make LFP battery cells exceeding 600 Ah for stationary storage. Cumulative production has now surpassed one million cells, demonstrating both manufacturing scale and product maturity.
The cells are part of EVE Energy’s Mr. Flagship series designed for battery energy storage system applications. The 628 Ah Mr. Big cell is integrated into the Mr. Giant system – a 20-foot containerised unit with up to 5 MWh energy storage capacity and suitable for 4+ hour long-duration storage.
