Gotion High Tech has introduced its latest lithium iron phosphate (LFP) utility-scale battery energy storage products, pushing the boundaries of energy density in standard 20-foot containers. The company unveiled these innovations at the 2025 Japan International Secondary Battery Exhibition.
During the event, Gotion secured sales framework agreements with several globally recognized energy firms, totalling over 7 GWh in orders. This milestone underscores the growing demand for advanced battery energy storage solutions.
Enhanced Storage Capacity and Footprint Reduction
The latest twenty-foot container system from Gotion delivers 40% more energy while occupying 40% less space compared to conventional 5 MWh systems. The system relies on 587 Ah battery cells, which offer an impressive energy density exceeding 430 Wh/L. Each cell provides a capacity of 1.87 kWh and boasts a cycle life exceeding 12,000 cycles, with an expected calendar life of over 25 years.
Introduction of Large-Capacity Cells
At the Japan exhibition, Gotion also showcased its first 600+ Ah battery cells. The company officially introduced a 650 Ah energy storage cell and displayed an even larger 688 Ah cell at its booth.
Developed in collaboration with CRRC Zhuzhou Institute, the 688 Ah battery successfully passed testing in late January. This high-capacity cell achieves an energy density of 435 Wh/L and offers a single-cell capacity of 2.2 kWh. It supports over 10,000 charge-discharge cycles and features a calendar life exceeding 20 years.
Optimized Energy Storage for Greater Efficiency
Equipping a twenty-foot standard container with 688 Ah cells increases system capacity to over 6.9 MWh. Compared to 5 MWh alternatives, this configuration reduces floor space by 20%, minimizes the number of components by 20%, and lowers initial costs by approximately 8%.
Gotion emphasizes that these advancements enable greater cost efficiency and performance improvements for utility-scale battery energy storage systems (BESS). The new systems require less land, reduce investment costs, and provide ultra-long lifecycle and extended-duration storage.
Competitive Landscape in High-Capacity Cells
Other leading battery manufacturers have also introduced high-capacity cells. Envision, for instance, offers a 700 Ah cell in its cutting-edge 8 MWh, 20-foot BESS container, while Hithium has launched a 1,175 Ah cell featured in its latest 6.25 MWh BESS with a four-hour energy storage configuration.
As reported by pv-magazine-india.com, Gotion’s latest advancements showcase the industry’s push for higher energy density and longer life cycles. They also highlight more efficient battery storage solutions, reinforcing Gotion’s position as a key player in the global BESS market.
