Abstract

The present invention provides a deformation detection sensor for a sealed secondary battery, that makes it possible to detect deformation resulting from swelling of a cell with a high degree of sensitivity, that does not restrict capacity, and that has excellent stability. The deformation detection sensor for a sealed secondary battery includes a polymer matrix layerand a detection unit. The polymer matrix layercontains a magnetic filler that is dispersed therein and that changes an external field in accordance with deformation of the polymer matrix layer. The detection unitdetects change in the external field. The polymer matrix layeris sandwiched in a gap between adjacent cellsand mounted in a compressed state.
