Investigation of multifactorial effects on the thermal performance
Moraga et al. [27] compared the cooling efficiency of one or three layers of different PCMs, while Nasehi et al. [28] investigated a three-layer PCM-wrapped battery pack composed of 100 cylindrical cells. The results illustrate that the cooling effect is better when the high thermal conductivity PCM is close to the battery surface.

Insulation Materials Preventing EV Battery Short Circuits
In modern EV battery packs, cells are densely packed to maximize energy density, with spacing between cells often less than 1mm. During normal operation, these cells can experience voltage differentials exceeding 400V, while thermal events can drive temperatures above 150°C—creating conditions where even minor insulation failures risk catastrophic short
