 Graphene is a two-dimensional, 2D material with unique thermal properties. Recent studies have focused on its thermal conductivity, which can be significantly enhanced by reducing the thickness of the graphene layer or by introducing defects into it. Graphene enhanced phase change materials, JEPMs, which combine graphene with traditional phase change materials, show promise for thermal management of high power density batteries. JEPMs offer higher thermal conductivities than conventional phase change materials, due to their improved thermal conductivity and reduced thermal resistance. This article was authored by Jackie D.
