【 摘 要 】

tsA three-dimensional spider web-inspired structured graphene skeleton is constructed.The spider web-like skeleton endows paraffin wax with a significantly high longitudinal and transverse thermal conductivity enhancement of ~1260% and ~840%, respectively, at 2.25 vol% skeleton.The resultant composites exhibit outstanding performance on the thermal management of Li-ion batteries.
