Manchester University team discovers energy storage mechanism in bi-layer graphene anode

A team of scientists from the University of Manchester has gained new understanding of lithium-ion storage within the thinnest possible battery anode - composed of just two layers of carbon atoms. Their work shows an unexpected ‘in-plane staging’ process during lithium intercalation in bilayer graphene, which could pave the way for advancements in energy storage technologies.

Lithium-ion batteries, which power everything from smartphones and laptops to electric vehicles, store energy through a process known as ion intercalation. This involves lithium ions slipping between layers of graphite - a material traditionally used in battery anodes, when a battery is charged. The more lithium ions that can be inserted and later extracted, the more energy the battery can store and release. While this process is well-known, the microscopic details have remained unclear. The Manchester team’s discovery sheds new light on these processes by focusing on bilayer graphene, the smallest possible battery anode material.

Xiaomi launches a graphene radiator capable of heating a room in a few seconds

Xiaomi has released its new Xiaomi Mijia Graphene Skirting Board Heater 2, a graphene radiator that boasts a powerful heating system 2.200W and a foldable format. The Xiaomi Mijia Graphene Skirting Board Heater 2 features a graphene heating technology heater capable of providing heat in just 3 seconds and heating an entire room to the desired temperature in just 15 minutes.

In 2022, Xiaomi launched the Mijia Graphene Baseboard Heater (Fire Edition). The device uses two graphene-based heating elements, and has a simulated flame function that uses an integrated humidifier and LEDs to generate the flame appearance. This new launch seems to be the next generation in the same product line.

Graphene Manufacturing Group gives update, says its Richlands plant "exceeds hopes"

Graphene Manufacturing Group (GMG) has provided a business update on its recently commissioned modular graphene production plant at Richlands, Australia. The graphene production plant has been operating and producing graphene since its commissioning date in December, 2023.

The performance of the production unit, according to GMG's CEO and managing director, Craig Nicol, has "exceeded the Company's expectations in both graphene production rate and graphene quality. The company continues to perform minor optimizations with this new production plant which have both increased production yield and quality of the graphene".

Haydale and Jersey Energy Technologies announce underfloor heating pilot in Jersey

Haydale has announced that it has signed a contract with Jersey Energy Technologies ("JET"), a start-up company focused on providing energy efficiency solutions across the Channel Islands, to begin a pilot trial deploying Haydale's underfloor heaters within social housing in Jersey.

Haydale's underfloor heating system utilizes the Company's proprietary HDPlas functionalization technology to unlock the high-level thermal conductivity properties of graphene. Data gathered from Haydale's in-house prototype systems implies up to 30% lower operating cost for their functionalized graphene ink underfloor heating compared to standard wired systems running off mains power. In test conditions, the heaters, which can be uniformly and individually heated, have also shown improvements in flexibility, and durability; reaching maximum temperatures quickly. This presents a potential commercial solution to meet the demand for improved energy efficiency, reducing heating costs for residents without trade off.

Archer to test for chronic kidney disease on its Biochip gFET sensors

Archer Materials has started experiments to detect and monitor chronic kidney disease on its Biochip graphene field effect transistor (“gFET”) sensors.

Archer, through one of its foundry partners, has reportedly verified a process that directly grows graphene surfaces to produce enhanced devices, rather than transferring the graphene to a device from a wafer, as previously done. The team has tested the devices by storing them in normal air conditions over a two-month period, finding no significant degradation in performance.

Researchers develop scalable graphene technology for regulating heat transfer and enhancing battery safety

Researchers at Swansea University, in collaboration with China's Wuhan University of Technology and Shenzhen University, have developed a technique for producing large-scale graphene current collectors that could significantly enhance the safety and performance of lithium-ion batteries (LIBs).

Their recent study details the first successful protocol for fabricating defect-free graphene foils on a commercial scale. These foils offer excellent thermal conductivity - nearly ten times higher than traditional copper and aluminium current collectors used in LIBs.
