Graphene copper tape

Graphene copper tape used in mobile phone etc.

Graphene copper tape is a key thermal management tool in mobile phones, merging graphene's excellent thermal conductivity with copper's strong heat transfer. It’s placed in tight spots like between the battery and mid-frame, or near high-power parts such as the charging module and image signal processor.​
It creates efficient thermal paths, with graphene speeding up heat spread across copper, and copper conducting heat to the metal chassis or cooling fins. This stops hotspots—like near the camera during 4K shooting or the processor during heavy use.​
Thin, flexible, and with adhesive backing, it fits easily into compact phone designs, maintaining contact despite thermal expansion. In 5G phones, it’s crucial for stable performance, channeling heat from sensitive components to keep the exterior cooler.​
