Cylindrical Cell

Cylindrical lithium-ion batteries are a popular type of rechargeable battery, known for their reliable performance and durable design. Each cell features a metal cylinder that houses the core components: positive and negative electrodes, a separator, and electrolyte. The most common type of cylindrical lithium-ion battery is the 18650 cell, named for its dimensions: 18 millimeters in diameter and 65 millimeters in length. While the 18650 cell is the most well-known, there are other cylindrical cell form factors, such as 2170 and 4680 cells, each with different dimensions and specifications.
