Abstract
Various arrangements for compressing a cylindrical battery cell are presented herein. The cylindrical battery cell may be wrapped in a buffer material. The buffer material may then be compressed using a compression mechanism. The buffer material may uniformly distribute pressure applied to the buffer material to a curved sidewall of the cylindrical battery cell. The cylindrical battery cell may be heated while the buffer material is being compressed using the compression mechanism.
