Experimental investigation on thermally induced aluminum nitride based flexible composite phase change material for battery thermal management

•Thermally induced flexible and form stable phase change material (PCM) is prepared.•Styrene butadiene styrene has positive effect on structural stability of composite PCM.•Aluminium nitride increases the thermal conductivity of the flexible composite PCM.•Flexible composite PCMs exhibit excellent battery thermal management effect.•Flexibility can be achieved when temperature over the melting point of paraffin.
