A Demonstration of the potential for high scalability in producing BNNS-TIMs using a precision cutting machine. The BNNS-TIMs of 30 × 30 × 1 mm were produced in just 7 s per piece. B Temperature–time curves showing the advantage of BNNS-TIMs in heat dissipation under a normal packaging pressure (43.5 psi), with a commercial product (Henkel TSP3500) and no TIMs as references. The heating process lasts for 300 s at a certain power density, followed by ambient cooling. C The equilibrium temperature of the heater surface is shown for power density increasing from 5 to 20 W cm−2 (43.5 psi). D and E The BNNS-TIMs were used for a fast-charging battery for mobile phones. Infrared images were taken for three different scenarios, without TIMs, with a commercial TIM, and with BNNS-TIMs used after fast-charging for 60 s. The corresponding temperature–time curves for the charging duration were also recorded, and a picture of the 120 W-charging battery is also shown.
