Global Cylindrical Battery Cells for Power Bank Market Strategic Research Report

Scope of the Report

The global Cylindrical Battery Cells for Power Bank market size is predicted to grow from US$ 1,370 million in 2025 to US$ 1,751 million in 2032; it is expected to grow at a CAGR of 3.6% from 2026 to 2032.

Cylindrical Battery Cells for Power Banks refer to primary-packaged lithium-ion cells with a cylindrical metal casing, used in portable mobile power products. Common sizes include 18650 and 21700. These cells are characterized by high energy density, long cycle life, strong safety performance, and mature manufacturing processes. Compared with prismatic or pouch-type cells, cylindrical cells offer superior cell consistency, efficient thermal management, high automation compatibility, and cost-effectiveness. They have become a mainstream solution in mid-to-high-capacity power banks, particularly suited for outdoor power supplies, high-power bidirectional fast charging, and high-frequency usage scenarios.

In 2025, production was approximately 1,167 million units and the average price was USD 1.2 per unit. The industry’s capacity utilization rate in 2025 was about 65% and the average gross margin was around 20%. Upstream, the key materials include cathode materials, anode materials, electrolytes, and separators, with representative suppliers such as BTR, Shanshan, Tinci Materials, Capchem, Yunnan Energy New Material, and Senior Technology supporting the core material system for cylindrical lithium-ion cells. The midstream segment focuses on cell design, winding process control, electrolyte injection, formation and grading, safety testing, consistency management, and automated mass production, which together determine cell capacity stability, cycle life, discharge performance, safety reliability, and unit cost competitiveness. Downstream, Cylindrical Battery Cells for Power Bank are mainly supplied to power bank manufacturers, with representative customers including Anker Innovations, Xiaomi, Baseus.

As power banks move toward higher capacity, faster charging, and stricter safety compliance, cylindrical battery cells will continue to benefit from their standardized format and mature manufacturing base. Their value is no longer defined only by low cost, but by the ability to deliver stable discharge, consistent cell matching, and predictable thermal behavior in compact battery packs. For branded power bank manufacturers, reliable cylindrical cells help shorten product development cycles and support platform-based designs across different capacity ranges. Competitive suppliers will focus on energy density improvement, safety chemistry optimization, automated production control, and long-term quality consistency, which are becoming the core levers for profitability rather than simple capacity expansion.
