Cylindrical batteries are widely used globally thanks to portability and flexible packaging advantages. Their tubular shape makes it well-suited for everything. Whether it’s tiny button cell uses, or larger high-capacity uses like EVs, they are a great pick. As the demand for cylindrical lithium-ion batteries keeps growing across sectors, learning about the different lithium battery classification styles used becomes increasingly essential.
This article aims to provide an overview of the two major attributes. These include chemistry and size. They are used to differentiate between cylindrical cell types. By clarifying the properties of each category, you will gain insights into selecting the optimal battery for specific applications and use cases.

The First Cylindrical Lithium Battery Classification Method: Cell Chemistry
The most common cell chemistries used in cylindrical battery form are lithium-ion and lithium metal. Lithium-ion batteries commonly have a graphite-based anode paired with a cathode of lithium cobalt oxide. Sometimes, it is made of nickel, manganese cobalt oxide, or lithium iron phosphate. A lithium salt electrolyte is used, which is dissolved in an organic solvent. It facilitates the flow of lithium ions. They flow between the cathode and anode during charging and discharging. This classification has become widely adopted due to many perks. These include high energy density and lack of memory effect that plagues other rechargeable tech.
However, ongoing research also focuses on developing improved lithium metal battery designs using metallic lithium as the anode material. This offers an even higher possible energy density. However, challenges remain in developing stable cyclability due to issues. These include dendrite formation and liquid electrolyte decomposition. Engineers continue working to enhance lithium metal cell stability. The key are the modifications to cathode compositions and solid-state electrolyte solutions. If technical obstacles can be overcome, lithium metal batteries may eventually find widespread usage in high-power applications. These include electric vehicles that demand maximum energy storage capacity.

The Second Cylindrical Lithium Battery Classification Method: Battery Size
Cylindrical batteries are also classified based on size. They are available in standardized dimensions that make a manufacturer more easily choose the favorable battery model for their product. Here’s a chart to make you understand it better:
Battery Type | Battery Size (Diameter * Height) (mm) |
AA | 14.5 × 50.5 |
AAA | 10.5 × 44.5 |
AAAA | 8.3 × 42.5 |
C | 26.2 × 50 |
D | 34.2 × 61.5 |
18650 | 18 × 65 |
21700 | 21 × 70 |
Different Cylindrical Lithium Battery Classification in Different Applications
The cylindrical lithium batteries classification is ideal for use in a variety of portable devices and applications. This is thanks to stability, energy density, and the ability to be uniformly manufactured in different sizes. The following table outlines common uses seen across industries for some prevalent cell chemistry and size types:
Battery Type | Applications |
Lithium-Ion | Power Tools, Laptops, Power Banks, Electric Vehicles |
Lithium Metal | Medical Devices, Military Equipment, Aerospace |
AA/AAA | Remote Controls, Toys, Flashlights |
C/D | Lanterns, Camping Gear |
18650 | Power Tools, Laptops, E-cigarettes, EV Battery |
21700 | Power Tools, Electric Scooters |
