BAK Battery has introduced its 85Ah prismatic cell designed for AIDC power storage applications. The cell uses high-rate discharge capability, low internal resistance design, and a robust safety system to deliver stable energy support for AI infrastructure.
Industry observers view 2026 as the breakout year for large-scale AIDC storage deployment. According to the 2026 Global Energy Storage Industry White Paper from SPIR, global shipments of AIDC energy storage systems reached 10 GWh in the first five months of 2026 alone, exceeding the total for all of 2025. Full-year shipments are projected to hit 30 GWh, with that figure expected to reach 400 GWh by 2030. AIDC is becoming a major new growth driver for the storage sector.
Why AIDC Needs Faster, More Flexible Storage
AIDC facilities feature high computing density, massive electricity consumption, and sharp load fluctuations. As AI workloads grow exponentially, conventional power architectures built around steady-state loads and long-duration backup are showing insufficient response speed and flexibility. Computing now requires three things from energy systems: greater power delivery capacity, millisecond-level reaction times, and highly stable operation. Storage is no longer just emergency backup — it must also provide instant power support and active regulation to buffer rapid changes in computing loads.
BAK 85Ah Cell Specs and Performance
Based on high-rate LFP chemistry with a winding-stacked electrode design, BAK's 85Ah prismatic cell focuses on high-power output, ultra-low internal resistance, and reliable safety. It supports continuous discharge up to 12C with a maximum peak power of 2,500 W. The cell can release pulse power in milliseconds, enabling zero-delay response for AIDC power systems.
Internal resistance is kept at or below 0.3 mΩ, reducing energy loss and heat during high-current charge and discharge. At 6C discharge, temperature rise stays under 30°C. The cell delivers over 2,000 cycles at 1C charge and 6C discharge. Operating temperature range is –20°C to 60°C.
Safety Certifications and Mass Production
The 85Ah cell has passed nail penetration, overcharge, over-discharge, short circuit, and high-temperature tests. It holds UL9540A and UL1973 certifications. Now in mass production, the cell is ready to support the accelerated rollout of AIDC storage.
BAK says it will continue deepening technology innovation and product iteration around emerging application scenarios, helping build a safer and more reliable energy foundation for the digital economy.
