Introduction: Researchers at the University of Queensland and Brisbane-based Graphene Manufacturing Group (GMG) are collaborating to develop a faster-charging, more sustainable battery prototype that can last three times longer than current lithium-ion batteries.


The "graphene revolution" is coming, and Australian scientists who specialize in aluminum-ion batteries are now working with a Brisbane-based graphene manufacturing group to commercialize a technology that could transform energy storage.


GMG, which recently listed on Canada's TSX Venture Exchange, has entered into a research agreement with scientists at the University of Queensland's Australian Institute of Bioengineering and Nanotechnology (AIBN) to develop solutions for everything from watches to grid storage and everything in between. Make batteries for everything, including phones, laptops and electric cars.


The UQ technology, which pairs aluminum-ion batteries with graphene electrodes, was devised by Professors Michael Yu, Xiaodan Huang and postdoctoral student Yueqi Kong as a way of making graphene into more efficient electrodes to power the batteries. The technology has been patented and licensed from UniQuest, the University of Queensland's commercialization company.

Graphene is the wonder material of our time. It's the thinnest and strongest material known to science, and if that wasn't enough, it's also a great conductor of electricity - even better than copper.


Essentially, graphene is just good old carbon, but it's tessellated in such a way that incredibly strong bonds occur between atoms.


Still, UQ and GMG are not the only ones making progress. In March, scientists from Dalian University of Technology in my country and the University of Nebraska in the United States collaborated to create a battery composed of a pure aluminum anode, a graphene cathode and an organic electrolyte.


Back in 2019, scientists at Royal Melbourne Institute of Technology (RMIT) demonstrated a laser printing process that allowed graphene supercapacitors to be embedded directly into textiles, creating a fabric that could store energy and integrate with solar cells. Used to power smart fabric applications.


AIBN Director Professor Alan Rowan said: "Tests have shown that rechargeable graphene aluminum-ion batteries have three times the battery life of currently leading lithium-ion batteries. The higher power density means they can charge up to 70 times faster."

Charging temperature: 0~45℃ Discharge temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ Discharge capacity retention rate: 0.5C Discharge capacity ≥ 60%


"This battery can be recharged through more cycles without loss of performance and is easier to recycle, reducing the possibility of harmful metals leaching into the environment," Rowan said.


UniQuest CEO Dean Moss said he believes aluminum-ion batteries with graphene electrodes can transform the existing rechargeable battery market. Lithium-ion batteries require large amounts of water to extract rare earth materials and are processed using chemicals that can harm the environment.


It is understood that scientists from the University of Queensland received a three-year A$390,000 (US$303,600) grant from the Australian Research Council Linkage Project in 2020 to develop graphene aluminum ion technology.
