CBAK Energy advances full-tab LFP cells for AI data center backup power as gas plants fill the grid gap

After 15 months of dedicated development, CBAK Energy Technology's Dalian subsidiary has moved two new full-tab cylindrical lithium iron phosphate cells into customer testing, positioning the company squarely in the race to supply battery backup infrastructure for AI data centers. The two variants, the 26650 HP V2.0 and the 26650 PFS2 V2.0, are now in the sample validation phase with multiple enterprise customers, who are simultaneously running module-level verification, according to a release issued today via GlobeNewswire.

The program was led by Huabin Dai, deputy general manager of Dalian CBAK Power Battery Co., Ltd., a wholly owned subsidiary of CBAK Energy. In an interview cited in the same release, Dai described the cells' three core performance advantages as being targeted directly at the high-rate charge and discharge demands of AI data center battery backup units, known as BBUs, and uninterruptible power supplies. Early test feedback from lead customers has been favorable, and the company says commercialization timelines are accelerating.

Why BBU cell specs matter at the infrastructure level

BBUs are the last line of defense between a power interruption and a server rack going dark. In conventional data centers, the power draw is relatively predictable. AI inference and training workloads change that calculus: GPU clusters can swing from near-idle to full draw in milliseconds, placing demands on backup cells that standard energy-density specs were never designed to meet. High-rate LFP chemistry addresses that through a combination of thermal stability and the ability to deliver large current bursts without the degradation risks associated with other lithium chemistries.

The full-tab construction in CBAK's new cells reduces internal resistance by increasing the contact area between the electrode and current collector, a design choice that directly supports the high-current performance AI backup applications require. For procurement teams specifying backup power at the cell or module level, this distinction matters when evaluating total cost of ownership over a multi-year data center lifecycle.

The grid backdrop: gas is filling the AI power gap

The push to qualify better backup cells is happening against a turbulent grid backdrop. The Associated Press has reported that the explosive growth of AI-driven data center power demand is outpacing the buildout of new renewable generation and the transmission infrastructure needed to move it. The result is that gas-fired plants are moving back to the front of the queue, even as hyperscalers and colocation operators maintain public commitments to clean energy targets.

For data center operators and the facilities teams who keep these campuses running, the energy mix question and the backup power question are increasingly connected. Renewable sources with intermittent generation profiles make on-site energy storage, including BBU and UPS systems, more operationally critical, not less. A grid that depends more heavily on weather-sensitive generation is one where the reliability of cell-level backup performance carries greater consequence.

Alternative energy infrastructure demand is lifting adjacent markets

The broader appetite for energy infrastructure investment is showing up in financial results across the sector. Beam Global, which makes solar-integrated EV charging and energy storage products for government and commercial customers, reported preliminary second-quarter 2026 revenue exceeding $8.5 million, more than 170 percent above its first-quarter figure and more than 20 percent above the same period a year earlier, according to a GlobeNewswire announcement today. While Beam operates in a different segment than data center backup, the sequential revenue jump reflects a market where procurement budgets for energy infrastructure hardware are expanding.

For enterprise infrastructure leaders, the CBAK cell validation milestone signals that the supply side of the AI backup power market is maturing. Manufacturers are now running full customer qualification programs at scale, not just releasing technical datasheets. Teams evaluating BBU or UPS component sourcing over the next 12 to 18 months will likely see more qualified LFP options entering the market as these validation cycles complete.

What this means for your team

• Engage backup power suppliers now on LFP cell roadmaps: CBAK's customer validation cycle suggests qualified high-rate LFP options will be available for module-level procurement within the next product cycle. Ask current and prospective suppliers whether their BBU and UPS designs are qualified for AI workload power profiles, not just traditional IT loads.
• Revisit BBU specifications for AI infrastructure: If your data center hosts GPU-dense AI workloads, confirm that backup power specs account for high instantaneous current draw. Cell chemistry and construction, including full-tab versus conventional tab designs, affect how well a BBU holds up under those conditions.
• Factor grid reliability into on-site storage sizing: As the Associated Press reporting highlights, the grid mix supporting AI campuses is shifting. Data center and facilities teams should model backup runtime and storage capacity against a scenario where renewable intermittency increases, not just against traditional outage events.
• Track alternative energy hardware lead times: Beam Global's sharp sequential revenue increase signals strong demand for energy infrastructure products. Supply chain teams should watch for potential lead-time pressure on backup and storage hardware as procurement activity accelerates across the sector.
