Cylindrical cells are one of the most common battery types used in electric vehicles. Tesla recently improved on the typical cylindrical cell design, developing a new tab design that allows for a much larger cell. [1,2] With this design, a single battery pack only requires 900 cells — as opposed to the roughly 7,000 cells contained in a traditional pack — which offers multiple advantages: It is easier to manufacture the battery pack, and there are fewer cells as well as fewer cans and contacts per pack, which means that there is a larger amount of active battery material in relation to the can material and other nonactive materials.
