HiTHIUM, a globally recognized energy storage technology company, has officially commenced mass production and initiated first deliveries of its high-capacity ∞Cell 587Ah battery at its Xiamen facility. This achievement signals the energy storage sector’s transition into what industry observers are calling the “500Ah+ high-capacity era,” underscoring HiTHIUM’s manufacturing capability and supply chain reliability.

The ∞Cell 587Ah is the result of three years of focused research and represents a major step in battery industrialization. With the global push toward renewable energy, large-capacity storage solutions have become essential for improving system efficiency, reducing costs, and ensuring operational safety.

Beginning its long-duration storage research in 2022, HiTHIUM introduced the world’s first 1000Ah+ cell and a 6MWh+ system in 2023. The newly released 587Ah model is derived from the ∞Cell 1175Ah and shares compatibility with the same ∞Pack and ∞Power platforms. It incorporates innovations in chemistry, production process, and structural design, achieving 94.5% efficiency, a lifecycle exceeding 10,000 cycles, and broad application adaptability.

Simultaneously, the company has launched the ∞Power 6.25MWh system designed for two-hour applications, which utilizes the ∞Cell 587Ah. This release further diversifies HiTHIUM’s product offerings, extending their reach across various energy storage scenarios.

To support high-volume production, HiTHIUM upgraded its Xiamen manufacturing base into a fully digitalized and intelligent production line. These enhancements led to a 17.1% increase in production efficiency and a process capability index (Cpk) exceeding 1.33. Through multi-pass anode rolling, improved interface control, and precision temperature management, electrode rebound was reduced by more than half and temperature accuracy raised by 50%. The production line now operates at PPB-level defect rates, reflecting exceptional quality control.

Nearly 2,000 intelligent devices enable full automation with real-time data collection. AI-assisted visual inspection systems are deployed across over 13 stations, utilizing more than 390 CCD and 3D cameras capable of identifying defects as small as 0.3 mm.

As demand for high-capacity energy storage grows, HiTHIUM’s ∞Cell 587Ah is positioned to play a central role in advancing industry standards. With its proven expertise in large-capacity battery technology and intelligent manufacturing, HiTHIUM continues to support the global energy transition with high-performance, dependable storage solutions.
