  "textContent": "There is provided a method of making a plurality of anti-thermal propagation cell spacers for use in a multi-cell battery pack. The method comprises providing a web of base film extending in a longitudinal direction. The web of base film comprises a first side and a second side. The first side of the web of base film is covered with an adhesive layer. The method also comprises providing a first plurality of insulation pads. The first plurality of insulation pads comprise a top face, a base face, a front edge, a back edge, a left side, and a right side. The method further comprises attaching the base face of an insulation pad of the first plurality of insulation pads to the first side of the web of base film, such that a left base film strip and a right base film strip of the web of base film remain unattached to the insulation pad. The method further comprises folding the left base film strip over the left side and at least a portion of the top face of an insulation pad of the first plurality of insulation pads. The method also comprises folding the right base film strip over the right side and at least a portion of the top face of an insulation pad of the first plurality of insulation pads. The method further comprises providing a first web of lidding film extending in the longitudinal direction. The first web of lidding film comprises a first side and a second side. The first side of the first web of lidding film is covered with an adhesive layer. The method also comprises attaching the first side of the first web of lidding film to at least a portion of the top face of an insulation pad of the first plurality of insulation pads, wherein the first side of the first web of lidding film is also attached to at least a portion of the left base film strip and of the right base film strip.",
