Global Cylindrical Lithium Battery for BBU Market Strategic Research Report

Scope of the Report

The global Cylindrical Lithium Battery for BBU market size is predicted to grow from US$ 154 million in 2025 to US$ 361 million in 2032; it is expected to grow at a CAGR of 12.8% from 2026 to 2032.

Cylindrical Lithium Battery for BBU refers to a cylindrical lithium-ion battery used as an energy storage cell in the battery backup unit, with common specifications including 18650 and 21700. It is composed of a 48V or higher voltage battery pack through series and parallel connection, and is equipped with a battery management system, fuse and relay protection, and necessary thermal management. In the event of instantaneous interruption or voltage drop of the main power supply, it quickly discharges at a high rate to provide millisecond level energy replenishment for the server power supply or DC bus; Compared to square and soft pack cells, cylindrical cells have higher consistency and supply chain maturity, clearer heat dissipation paths, and higher standardization of modular assembly. Therefore, they are more commonly used in rack level BBUs that require high power density and reliability. Key concerns include magnification and internal resistance, cycle life, thermal runaway safety design, group consistency, and long-term attenuation curves. In 2025, global Cylindrical Lithium Battery for BBU production reached approximately 114.85 M Units, with an average global market price of around US$ 1369 per k unit.

Cylindrical Lithium Battery for BBU has an annual production capacity of 1.6 million and a gross profit margin of around 20%.

Upstream: Lithium salt and lithium iron phosphate or ternary precursor and positive electrode materials, graphite negative electrode, electrolyte solvent and lithium salt, diaphragm base film and coating materials, copper foil and aluminum foil, steel shell and top cover components, etc.

Downstream: data centers and telecommunications, security and monitoring, industrial, medical, and others.

The raw material cost is 75%, the manufacturing cost is 15%, and the labor cost is 8%.

In the context of the explosion of AI, traditional Internet data centers (IDCs) are accelerating their evolution into artificial intelligence data centers (AIDCs). The high-performance computing, large-scale storage and high-speed network requirements of AIDCs have put forward higher requirements for backup power security. The high efficiency and timely performance of BBUs provide security guarantees for AIDCs. The current BBU industry supply chain is roughly "battery companies → equipment companies → server companies". Among them, battery companies are currently dominated by Japanese and Korean companies, accounting for more than 80% of the market share.
