Claim 0:
1. A battery cell pack comprising:
a prismatic frame;
a plurality of battery cells; and
a plurality of deformable separators;
wherein the plurality of battery cells are arranged in a horizontal stack within the prismatic frame;
wherein the plurality of deformable separators are interposed between subsets of the plurality of battery cells;
wherein the plurality of deformable separators exert a compressive force on the subsets of the plurality of battery cells along a longitudinal axis that is defined by the horizontal stack;
wherein each of the plurality of deformable separators comprises a compressible spring arranged within a spring holding structure;
wherein the spring holding structure comprises a first planar sheet and a second planar sheet opposed to the first planar sheet and each extending along a first axis that is perpendicular to the longitudinal axis;
wherein the first planar sheet has a first end extending along a second axis that is perpendicular to the first axis and parallel to the longitudinal axis;
wherein the second planar sheet has a second end extending parallel to the second axis and overlapping the first end;
wherein the compressible spring is interposed between the first planar sheet and the second planar sheet and abuts the first end;
wherein the spring holding structure includes an overlapping slide portion including the first end and the second end and configured to facilitate movement of the first end with respect to the second end along the second axis during compression of the deformable separator.
