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 are square battery cells?

As the name suggests square battery cells are prismatic or square-shaped lithium battery cells that have mostly steel or aluminum casings. The size, and shape of square batteries make them big capacity and less weight, and thus effectively suitable for tight spaces.

What is a cylindrical battery?

As the name suggests, cylindrical batteries are a set of electrodes that are tightly enclosed in a cylindrical-shaped cell that has generally a metal casing outside.

Why are battery cells cylindrical?

Most the battery cells are made cylindrical because it distributes the internal pressure evenly from the side reactions over the overall circumference of the cell thereby increasing the cell’s tolerance against deformation and higher internal pressure.
