Abstract

A battery module (10) comprises two parallel end plates (12) and one or more rows of cells (16) extending in a longitudinal direction (100) of the battery module (10) perpendicular to the two parallel end plates (12), each of the one or more rows of cells (16) comprising a series of prismatic battery cells (20, 22) and thermal insulation spacers (24, 26) repeated alternately along the longitudinal direction (100). At least one of the thermal insulation spacers (24, 26) is made of a state transition material, which exhibits an initial thermal conductivity higher than an initial thermal conductivity threshold (TCT1) at temperatures below 200°C and, when exposed to temperatures higher than a transition temperature (TT) between 220°C and 320°C, undergoes an irreversible transformation which results in a post-transformation thermal conductivity lower than a post-transformation thermal conductivity threshold (TCT2) that is less than the initial thermal conductivity threshold minus 0.5 Wm^-1K^-1, and less than 0.28 Wm^-1K^-1.
