Distinguished colleagues, industry leaders, and strategic investors,
For three decades, I have analyzed the global energy storage landscape, tracking the chemistries and form factors that power our portable world. Among the most established and widely deployed technologies is the cylindrical lithium cobalt oxide (LiCoO2) battery. This chemistry, combined with the mechanically robust and manufacturable cylindrical format, has been the workhorse of the consumer electronics revolution for decades and continues to play a significant role in powering a vast array of devices, from laptops to power tools.
The definitive guide to this substantial and still-growing market segment is the newly published report from QYResearch, “Cylindrical LiCoO2 Battery – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032.” The data within provides a comprehensive view of a market that, while facing competition from newer chemistries, maintains a significant position due to its high energy density and established manufacturing base.
Let us begin with the market’s impressive size and healthy growth trajectory. The global market for Cylindrical LiCoO2 Batteries was valued at US$ 10,590 million in 2024 and is projected to reach a readjusted size of US$ 16,680 million by 2031, growing at a compound annual rate of 6.8% during the 2025-2031 forecast period . This multi-billion dollar market underscores the enduring relevance of this chemistry, particularly in applications where high energy density in a compact form factor is the primary requirement.
At its core, a cylindrical LiCoO2 battery combines two well-proven technologies. The lithium cobalt oxide (LiCoO2) chemistry, first commercialized by Sony in 1991, offers a very high energy density, meaning it can store a large amount of energy in a small volume. This makes it ideal for space-constrained portable devices. The cylindrical format, with its classic “swiss roll” construction of electrode and separator layers, provides mechanical stability, excellent consistency in high-volume manufacturing, and proven safety when manufactured correctly. The core pain point for every product designer in sectors from consumer electronics to professional tools is now clear: how to achieve the maximum possible runtime in a device that must remain slim, lightweight, and affordable. The cylindrical LiCoO2 battery, in its various standard sizes, provides a proven and readily available solution.

The Drivers: Enduring Demand for High Energy Density and the Downstream Pull of Electrification
The 6.8% CAGR to a US$ 16.7 billion market is propelled by a combination of enduring demand from its core applications and the powerful tailwinds of the broader lithium-ion industry expansion.
First, and most fundamentally, is the sustained demand from its traditional strongholds. Laptop battery packs and power banks remain massive consumers of high-quality 18650 and other cylindrical LiCoO2 cells. The global shift toward mobile computing and the need for portable power on the go ensures a steady, multi-billion dollar annual demand from these sectors. The cordless power tools market is another major consumer, where the high energy density of LiCoO2 allows for compact, powerful batteries that can run professional-grade tools for extended periods. High-performance flashlights for tactical, outdoor, and industrial use also rely on these cells for their ability to deliver high currents and long runtimes in a slim package.
Second, while LiCoO2 is not the dominant chemistry in modern electric vehicles (EVs) , it continues to play a role, particularly in earlier EV models and in some hybrid and low-speed electric vehicles. Furthermore, the massive scale-up of the global lithium-ion industry, driven primarily by EVs, has profound benefits for all cell formats and chemistries. The QYResearch report details this explosive growth: global lithium-ion battery shipments reached 957 GWh in 2022, a 70% increase year-on-year, with China’s production alone hitting 750 GWh . This unprecedented scale of manufacturing investment has driven down costs, improved manufacturing consistency, and strengthened the entire supply chain for raw materials like lithium and cobalt, directly benefiting the LiCoO2 cylindrical cell market.
Third, the specific advantages of LiCoO2—particularly its high energy density and stable voltage plateau—make it difficult to completely displace in applications where space is at an absolute premium. While NMC (Nickel Manganese Cobalt) and other chemistries have made inroads, LiCoO2 remains a highly competitive choice for many consumer electronics and professional applications.
The Form Factor Advantage: A Range of Standard Sizes
The QYResearch report segments the market by the specific cylindrical form factor, highlighting the versatility of this technology. The extensive list includes many of the most common cell sizes in use today:
- 18650: The undisputed workhorse of the industry, used in countless laptop packs, power tools, flashlights, and even early EVs. Its standardized dimensions and massive production volume make it the most cost-effective and widely available format.
- 26650, 22650, 21700: Larger format cells offering higher capacity and discharge rates, increasingly used in high-end power tools, e-bikes, and some energy storage applications.
- 18490, 17500, 14650, 14500, 14430: These smaller and intermediate sizes are essential for slimmer devices, medical equipment, compact flashlights, and other applications where the 18650 is simply too large.
This diversity of form factors allows device designers to select the optimal cell size for their specific product, balancing capacity, power, and physical dimensions. The standardization of these sizes ensures multiple sources of supply and a mature manufacturing infrastructure.
