Abstract: The potential of graphene and few-layer graphene to be used as fillers in a paraffin wax phase change material (PCM) was evaluated. The goal was to prepare a composite PCM with a higher thermal conductivity than the pure paraffin wax. The ability of the composite PCM to reduce temperature variation in lithium ion batteries was also evaluated over 10 charging – discharging cycles. It was found that the composite PCM was better able to reduce the temperature rise induced by charging and discharging than the pure paraffin PCM.
