Technical FAQs 4

What is the difference between a square and a cylindrical battery?

Though both type of batteries use metallic casing for safety protection, the weight of the cylindrical cells is greater than that of square cells. As the name suggests square battery cells are prismatic or square-shaped lithium battery cells that have mostly steel or aluminum casings.

What is the shape of a lithium ion battery?

Lithium-ion batteries are normally either cylindrical or cubical in shape depending on manufacturer. For instance, most of the Li-ion cells used in laptop batteries are cylindrical and normally pink or blue in color depending on the battery manufacturer. The cylindrical cells are normally 18mm in diameter and 65mm in length.

What is a cylindrical battery?

At present, cylindrical batteries are mainly steel-cased cylindrical lithium iron phosphate. This cylindrical battery has high capacity, high output voltage, and good charge and discharge cycle performance. Lithium iron phosphate belts are promised to be used in solar lamps, lawn lamps, backup energy sources, power tools, toy models, etc.

What is a cylindrical lithium-ion battery?

For individual customer inquiries, please contact the support services for the equipment in use. A cylindrical lithium-ion battery is a type of lithium-ion battery with a cylindrical shape using a metal can as its packaging material.
