<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Range anxiety, recycling and fast-charging fears could all be consigned to electric-vehicle history with a nanotech-driven Australian battery invention.</span>
</div>
<div>
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333; background: yellow;">The graphene aluminum-ion battery cells from the Brisbane-based Graphene Manufacturing Group (GMG) are claimed to charge up to 60 times faster than the best lithium-ion cells and hold three time the energy of the best aluminum-based cells.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">They are also safer, with no upper Ampere limit to cause spontaneous overheating, more sustainable and easier to recycle, thanks to their stable base materials. Testing also shows the coin-cell validation batteries also last three times longer than lithium-ion versions.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">GMG plans to bring graphene aluminum-ion coin cells to market late this year or early next year, with automotive pouch cells planned to roll out in early 2024.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Based on breakthrough technology from the University of Queensland’s (UQ) Australian Institute for Bioengineering and Nanotechnology, the battery cells use nanotechnology to insert aluminum atoms inside tiny perforations in graphene planes.</span>

<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Testing by peer-reviewed specialist publication Advanced Functional Materials publication concluded the cells had “outstanding high-rate performance (149 mAh g−1 at 5 A g−1), surpassing all previously reported AIB cathode materials”.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">GMG Managing Director Craig Nicol insisted that while his company’s cells were not the only graphene aluminum-ion cells under development, they were easily the strongest, most reliable and fastest charging.</span>
</div>
<div>
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333; background: yellow;">“It charges so fast it’s basically a super capacitor,” </span>
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333; background: #F3F3F3;">Nicol claimed. “It charges a coin cell in less than 10 seconds.”</span>
</div>
<div>
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333; background: yellow;">The new battery cells are claimed to deliver far more power density than current lithium-ion batteries, without the cooling, heating or rare-earth problems they face.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“So far there are no temperature problems. Twenty percent of a lithium-ion battery pack (in a vehicle) is to do with cooling them. There is a very high chance that we won’t need that cooling or heating at all,” Nicol claimed.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“It does not overheat and it nicely operates below zero so far in testing.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“They don’t need circuits for cooling or heating, which currently accounts for about 80kg in a 100kWh pack.”</span>

</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">The new cell technology, Nicol insisted, could also be industrialized to fit inside current lithium-ion housings, like the Volkswagen Group’s MEB archicture, heading off problems with car-industry architectures that tend to be used for up to 20 years.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“Ours will be the same shape and voltage as the current lithium-ion cells, or we can move to whatever shape is necessary,” Nicol confirmed.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“It’s a direct replacement that charges so fast it’s basically a super capacitor.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“Some lithium-ion cells can’t do more than 1.5-2 amps or you can blow up the battery, but our technology has no theoretical limit.”</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Aluminum-ion battery cells are a hot bed of development, particularly for automotive use.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Recent projects alone have included a collaboration between China’s Dalian University of Technology and the University of Nebraska, plus others from Cornell University, Clemson University, the University of Maryland, Stanford University, the Zhejiang University’s Department of Polymer Science and the European Alion industrial consortium.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">The differences are highly technical, but the GMG cells use graphene from made from its proprietary plasma process, rather than traditional graphite sourcing, and the result is three times the energy density of the next-best cell, from Stanford University.</span>

<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Stanford’s natural graphite aluminum-ion technology delivers 68.7 Watt-hours per kilogram and 41.2 Watts per kilogram, while its graphite-foam bumps up to 3000W/kg.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">The GMG-UQ battery heaves that forward to between 150 and 160Wh/kg and 7000W/kg.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“They (UQ) found a way to make holes in graphene and a way to store aluminum atoms closer together in the holes.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“If we drill holes the atoms stick inside the graphene and it becomes a whole lot more dense, like a bowling ball on a mattress.”</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">The peer-reviewed publication Advanced Functional Materials found surface-perforated, three-layer graphene (SPG3-400) had “a significant amount of in-plane mesopores (≈2.3 nm), and an extremely low O/C ratio of 2.54%, has demonstrated excellent electrochemical performance.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“This SPG3-400 material exhibits an extraordinary reversible capacity (197 mAh g−1 at 2 A g−1) and outstanding high-rate performance,” it concluded.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Aluminum-ion technology has intrinsic advantages and disadvantages over the preeminent lithium-ion battery technology being used in almost every EV today.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">When a cell recharges, aluminum ions return to the negative electrode and can exchange three electrons per ion instead of lithium’s speed limit of just one.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">There is also a massive geopolitical, cost, environmental and recycling advantage from using aluminum-ion cells, because they use hardly any exotic materials.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“It’s basically aluminum foil, aluminum chloride (the precursor to aluminum and it can be recycled), ionic liquid and urea,” Nicol said.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“Ninety percent of world lithium production and purchasing is still through China and 10 percent is through Chile.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“We have all the aluminum we need right here in Australia, and they can be safely made in the first world.”</span>

<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">Listed on the TSX Venture exchange in Canada, GMG hooked itself in to UQ’s graphene aluminum-ion battery technology by supplying the university with graphene.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“Our lead product scientist Dr Ashok Nanjundan was involved in the University of Queensland project in its nanotechnology research centre in its early days,” Nicol said, admitting GMG almost “lucked into” the technology by supplying research projects with its graphene at no cost.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">GMG has not locked down a supply deal with a major manufacturer or manufacturing facility.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“We are not tied in to big brands yet, but this could go into an Apple iPhone and charge it in seconds,” Nicol confirmed.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“We will bring the coin cell to market first. It recharges in less than a minute, and it has three times the energy than with lithium,” the Barcaldine product said.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">“It’s a lot less adverse effect on health, too. A kid can be killed by lithium if it’s ingested, but not with aluminum.”</span>

<div>
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333; background: yellow;">Another benefit would be cost. Lithium has risen from US$1460 a metric tonne in 2005 to US$13,000 a tonne this week, while aluminum’s price has edged up from US$1730 to US$2078 over the same period.</span>
</div>
<div>
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333; background: yellow;">Another advantage is that the GMG graphene aluminum-ion cells do not use copper, which costs around US$8470 a tonne.</span>
</div>
<div style="background: #F9F5E9;">
<span style="font-size: 13.5pt; font-family: 'Sitka Text'; color: #333333;">While it is open to manufacturing agreements, GMG’s preferred plan is to “run” with the technology as far as it can, with 10 gigaWatt to 50gW plants, first, even if Australia may not be the logical first choice for the manufacturing facility.</span>
