Graphene is said to be a new wonder material which could be a game changer for a lot of industries. It’s a thin layer of carbon atoms and it is 200 times stronger than steel, making it one of the strongest materials ever made. This super light and flexible material is also said to have the highest thermal conductivity known to man.
Based on some leaked presentation slides, it appears that Huawei could turn to graphene to cool down its upcoming flagship devices.
While most smartphones makers are using liquid cooling, Huawei appears to be working on a graphene cooling solution and it might be introduced on the upcoming Mate 20 series. With better cooling, this will enable peak performance at all times without throttling under heavy load.
It isn’t clear how graphene will be utilised on the smartphone’s cooling solution but it could be applied like a thermal pad on its new Kirin 980 chip to conduct heat directly from its SoC. As a comparison, the Galaxy Note9’s “Water Carbon Cooling System” uses a Carbon Fibre interface. This helps to draw heat quickly from the processor before transferring it to its thermal spreader as shown below.
Apart from smartphones, Huawei could also incorporate graphene for its upcoming Matebook. As shown below, the upcoming Huawei laptop will also feature dual cooling tubes with two cooling fans.
This isn’t the first time Huawei had experimented with graphene as they have also explored the use graphene for Li-ion batteries. According to their research in 2016, graphite can enable Li-ion batteries to operate optimally at 60-degree celsius environments, which is 10-degrees higher than current limits.
On top of that, graphene can also help to double its overall battery lifespan. After recharging the battery 2,000 times at 60-degree celsius, the graphene assisted Li-ion unit could still retain 70% of its capacity.
