Graphene is a new material known for its excellent thermal conductivity and electrical properties. Graphene heating plate can achieve fast and uniform heat transfer by utilizing the high thermal conductivity of graphene, thereby improving heating efficiency.

[0003] Due to its excellent performance, graphene hot plate has broad application prospects in many fields.
