About Cylindrical battery pack module
The cans for the 18650 and 21700 are made from nickel plated steel and deep drawn in a two-stage process. The result is the base of the can is thicker than the cylindrical side wall. 1. 18650 1.1. Base thickness ~0.3mm 1.2. Wall thickness ~0.22 to 0.28mm 2. 21700 2.1. Base thickness ~0.3.
Cylindrical cells are used in numerous applications and cooling varies from passive through to immersed dielectric cooling. The.
Cylindrical cells are designed with a number of safety features including a defined vent path/weakness. The capacity is relatively small and hence the electrical and thermal energy content is smaller. Hence they are often.
