Graphene thermal conductivity - introduction and latest news - Page 6

The Honor Magic 4 Pro is about to be launched, and it is said to join a long list of mobile devices with graphene-based cooling technology.

The Honor Magic 4 series will reportedly adopt 'third-generation graphene technology superconducting hexagonal graphene' that improves the thermal conductivity by 50% compared with the first-generation graphene.

Interworld Electronics has released the BOXER-6641-PRO multi-core embedded controller from Aaeon, with a unique fan-less graphene heat sink chassis design that ensures an unprecedented operating temperature range of -40°C to 70°C.

Graphene-based cooling tech seems to be gaining popularity and is incorporated in various computer components (like MSI's RTX 3000 series GPUs), cellphones (like realme's GT 2 series, ZTE's Axon 30, Xiaomi's Mi 10 Ultra, various Huawei phones), and more.

Graphene-based cooling systems are becoming quite popular in today's cellphones, with many companies using it in their models. A few examples are: realme's GT 2 series, ZTE's Axon 30, Xiaomi's Mi 10 Ultra, various Huawei phones and more.

Now, it seems that Redmi's K50 e-sports has joined this team, with a recent disassembly test that found that its heat dissipation system makes use of graphene films. The test also reported 3D high-power graphite, large-area double VC, and heat dissipation copper sheet + boron nitride.

Haydale has announced it will be collaborating with Cadent Gas and the Energy Innovation Centre to develop graphene ink-based heaters for low-power hot water. The £135,000 three-stage project will run for an initial 15 months.

The graphene solution has the potential to offer a low-power way to heat water when there is an interruption to the gas supply. Currently, the provision of fan heaters and hot plates to vulnerable customers without a gas supply can be expensive and challenging, particularly for elderly or disabled customers.

At the recent CES event, South Korea-based Graphene Square presented its 'kitchen styler' - a transparent toaster that uses graphene.

In addition to tracking the level of toasting of the bread, the device is also said to offer 50% less power consumption and enable outdoor cooking with rechargeable batteries. The device is also foldable and expandable to dual cooking/warming plates and connects to mobile devices for recipe download/control.

realme has announced its new GT 2 series, marking the company’s first steps into the premium segment. The GT 2 series, equipped with various top-notch gear and AMOLED panels, is also said to be sporting a graphene-based cooling system.

As is the case with various other mobile phones and gadgets by the likes of Huawei and ZTE, the new GT 2 series will use a 3D liquid-cooled VC and graphene sheet cooling technology.

SmartIR, a spin-out of the University of Manchester, is working on a graphene-based smart coating for satellites, to allow them to control thermal radiation on demand, depending on whether a satellite’s surface is Earth’s shadow or on the side closest to the Sun.

This graphene technology is said to be a far more optimal solution as it is lightweight, has a low power consumption, can respond quickly to temperature changes, operates across the infrared spectrum, and involves no moving parts.

Sweden-based graphene fabric developer Grafren launched a new graphene-coated textile, branded G-HEATEX. The company says that this is the world's first active heating fabric.

According to Grafren, G-HEATEX fabrics supply powerful and uniform heat, while being soft, flexible, breathable and ultralightweight.

Three companies in China recently launched graphene-enhanced lead-acid batteries, and they claim the graphene materials boost the performance of the batteries. While it is hard to verify the exact content and composition of these batteries, it seems as if graphene is finally starting to enter the battery market.

First up is Tianneng battery, which offers its TNEH Series Deep Cycle Black Gold Battery. The company says that the graphene expands the cycle life of the batteries and improves the performance at low temperatures. The TNEH series offers a 20% longer cycle life compared to the company's non-graphene batteries. The same battery also offers a 5% increase in capacity at low temperatures.

Reebok launched a new apparel collection, called Thermowarm+Graphene, that uses graphene to help retain heat. Reebok says that by printing graphene on the internal side of the clothing, it helps to retain between 8% and 15% more heat than areas without graphene (that depends on the base fabric the graphene is printed on).

The new collection includes hoodies, jackets and pants. The collection is now available globally on Reebok's online store, with prices ranging from $70 to $140 USD. Reebok plans to release more options in the collection in the future.
