BAK 85Ah High-Rate Prismatic Cell Targets AIDC Energy Storage with Sub‑Millisecond Pulse Support

The global expansion of AI computing capacity is accelerating demand for energy storage in AIDC (AI data centers), injecting fresh growth momentum into the lithium‑battery industry as it enters the TWh era. Recently, BAK Battery officially introduced its 85Ah prismatic cell tailored for AIDC power storage applications, leveraging high‑rate discharge capability, low internal resistance design, and a robust safety system to deliver stable, efficient energy support for AI infrastructure.

Industry observers widely regard 2026 as the breakout year for large‑scale AIDC storage deployment. According to the 2026 Global Energy Storage Industry White Paper published by SPIR, global shipments of AIDC energy storage systems reached 10 GWh in the first five months of 2026 alone, surpassing the total for all of 2025. Full‑year shipments are projected to hit 30 GWh, with that figure expected to surge to 400 GWh by 2030. AIDC is rapidly emerging as a major new growth pole for the storage sector.

AIDC facilities are characterized by high computing density, massive electricity consumption, and sharp load fluctuations. As AI workloads scale exponentially, conventional power architectures—built around steady‑state loads, long‑duration backup, and fault protection—are increasingly showing insufficient response speed and limited flexibility. The computing side now imposes three non‑negotiable requirements on energy systems: greater power delivery capacity, millisecond‑level reaction times, and highly stable operation. Energy storage is no longer just a backup for emergencies; it must also provide instantaneous power support and active regulation to dynamically buffer rapid changes in computing loads.

Targeting AIDC Storage – BAK’s 85Ah High‑Rate Prismatic Cell

This upgraded role for AIDC storage places more stringent demands on the core cell, especially for high power and high safety. Based on a high‑rate lithium‑iron‑phosphate (LFP) chemistry and featuring a winding‑stacked electrode design, BAK’s 85Ah prismatic cell focuses on high‑power output, ultra‑low internal resistance, and reliable safety—offering a new cell option for AI data centers grappling with fast‑changing energy demands.

To address the instantaneous power spikes caused by volatile AI compute loads, the 85Ah cell supports continuous discharge up to 12C, with a maximum peak power of 2,500 W. It can release pulse power in milliseconds, enabling “zero‑delay” response for AIDC power systems and ensuring stable operations even under abrupt load changes.

Meanwhile, the cell’s internal resistance is kept at or below 0.3 mΩ, significantly reducing energy loss and heat generation during high‑current charge/discharge cycles. At 6C discharge, the temperature rise stays under 30°C, achieving a strong balance between high‑power delivery and operational efficiency. For the prolonged, high‑intensity operation typical of AIDC, the cell delivers over 2,000 cycles at 1C charge and 6C discharge, reconciling high performance with long‑term durability. Its operating temperature range of –20°C to 60°C further broadens deployment possibilities across varied climates and site conditions.

Beyond power performance, safety and reliability are decisive factors for AIDC adoption. The 85Ah prismatic cell incorporates structural safety designs and multiple protection layers, having passed stringent tests including nail penetration, overcharge, over‑discharge, short circuit, and high‑temperature exposure. It has obtained key safety certifications such as UL9540A and UL1973. Now in mass production, the 85Ah cell is positioned to support the accelerated rollout of AIDC storage with proven performance and stable supply capacity.

As AI competition intensifies, stable and efficient energy supply is becoming a critical foundation for sustained computing growth. BAK’s launch of the 85Ah prismatic cell not only addresses the high‑power storage needs of AIDC but also expands the company’s footprint in AI infrastructure energy solutions. Looking ahead, BAK Battery says it will continue to deepen technological innovation and product iteration around emerging application scenarios, helping build a safer and more reliable energy foundation for the digital economy.
