Lithium cells: differences, uses and how to choose the best ones
In this article, we’ll analyse the lithium cell formats available on the market and understand which are best for industrial applications.
One of the fundamental elements of lithium batteries is undoubtedly the cells they are made up of.
The 3 most common lithium cell formats in production today are:
- Cylindrical cells
- Pouch cells
- Prismatic cells
Cylindrical cells for lithium batteries are very similar to the batteries in our remote controls at home. The most common format is the 18650 cell (18mm diameter, 65mm height), with other formats such as the 21700, 26650 cell or custom solutions chosen by the cell manufacturer.
In lithium pouch cells, called this because of their package/envelope shape, the dimensions change significantly according to the construction choices of the manufacturer.
Prismatic lithium cells have a solid case, usually in plastic or metallic (aluminium) material, and have screw or welded terminals
Summarising the information above on lithium cells, we could say that:
- cylindrical cells are normally used in small lithium batteries (<2kWh), for example, electric bikes, screwdrivers, gardening tools, etc.). Only Tesla uses them in the automotive sector.
- pouch cells are mainly produced using NMC chemistry, and used especially in high-power applications (high voltage and low capacities) or in applications where a reduction in volume is required, for example, electric motorcycles or electric cars.
- prismatic cells are used for lithium batteries in the industrial sector and in the automotive industry to produce medium-large battery packs.
The best lithium cells for your industrial machinery
Flash Battery has chosen prismatic cells for its batteries precisely because of their characteristics.
They enable us to achieve high-quality performance in both industrial machinery and electric vehicle applications.
