RESUMO

Expanded graphite (EG)/paraffin wax (PW) composite phase change material (PCM) plate presents some advantages of low weight and preferable thermal conductivity in comparison with metal-foam/PW plate. However, the weak mechanical strength of EG/PW plate limits its practical use in battery thermal management of electronic vehicles. In this paper, we developed a new kind of composite plate combined EG/PW composite with aluminium (Al) honeycomb used in Li-ion thermal management. In this composite plate, Al honeycomb structure acts as a skeleton to further improve the thermal conductivity and mechanical strength of the composite plate. Additionally, we designed a single layer and double layers of Al honeycomb enhanced-EG/PW composite plates where PW consisted of RT35HC (melting point: 35 ℃) and RT44HC (41-44 ℃) for battery thermal management. The results show that double layers of PW composite plate presents the better effect in battery temperature controlling compared to a single layer of PW (RT35HC or RT44HC) at ambient temperature of about 30 or 40 ℃. The temperature difference of battery with double layers of PW was slightly larger than that with a single of PW.
