CBAK Energy Previews Next-Generation High-Rate LFP Cells for AI Data Center Backup Power

About this update from Cbak Energy Technology, Inc.

New 26650HP V2.0 and 26650PFS2 V2.0 cells are designed to support rack-level BBU applications and UPS scenarios requiring sustained high-rate power DALIAN, China, June 25, 2026 (GLOBE NEWSWIRE) -- CBAK Energy Technology Limited (NASDAQ: CBAT) ("CBAK Energy" or the "Company"), a leading lithium-ion battery manufacturer and electric energy solution provider in China, today previewed its next-generation high-rate lithium iron phosphate (LFP) cylindrical cells for AI data center battery backup unit (BBU) and uninterruptible power supply (UPS) applications. The rapid expansion of AI computing, particularly GPU-driven training and inference workloads, is increasing rack-level power density and accelerating transient load fluctuations in data center environments. At the battery backup unit (BBU) level, the key challenge is maintaining stable voltage under power transients within millisecond-level switching windows, where system stability is highly sensitive to rapid power fluctuations and thermal imbalance. To address these requirements, the 26650 HP V2.0 and 26650 PFS2 V2.0 cells developed as next-generation high-rate LFP cylindrical cells specifically designed for BBU applications and scalable to broader UPS scenarios. The two cells are designed to enhance high-rate performance, thermal stability, and power consistency, supporting four key advantages for AI data center backup applications: Supporting GPU Performance During Sudden AI Workload Surges In data centers, GPU workloads from large language model training and inference can surge suddenly, similar to traffic on a highway shifting from normal flow to peak-hour congestion within milliseconds. Backup power systems must respond quickly to help avoid computation slowdowns or interruptions. Compared with many conventional 15C-class cells, CBAK Energy's 26650 HP V2.0 (40C) and 26650 PFS2 V2.0 (38C) are designed to provide stronger high-rate response, supporting immediate power delivery during sudden workload spikes and helping data centers maintain GPU performance and millisecond-level backup operation at rack scale. Helping Reduce Interruptions During Critical Power Transient Events Beyond continuous operation, data centers can also experience brief but intense power surges during system switching or workload synchronization events, where even millisecond-level instability may lead to computing disruption or GPU reset. CBAK Energy's cells are designed to support up to 100C pulse discharge under specified test conditions, enabling rapid response to transient conditions and providing burst power support at peak demand. This capability acts like a real-time "shock absorber" for the power system, helping stabilize voltage at the moment of peak load and supporting continued GPU operation and stable backup performance.
