Australia’s rapidly growing electric vehicle market is putting renewed focus on how the country will manage thousands of large lithium-ion batteries once they reach the end of their useful lives. Industry experts say recycling infrastructure, specialist training and greater consumer awareness will need to keep pace with the expanding EV fleet.
Figures from the Federal Chamber of Automotive Industries show 27,089 battery electric vehicles (BEVs) were sold nationally in August, the highest monthly total for fully electric vehicles recorded in Australia. BEVs accounted for 24.9 per cent of the overall new vehicle market.
Electric Vehicle Growth Brings New Waste Challenge
The increasing popularity of EVs is expected to create a significant new stream of battery waste in Australia over coming years.
For motorists such as Marlene Caudillo, environmental considerations played an important role in the decision to move away from a petrol-powered vehicle.
Ms Caudillo bought her first EV about six months ago after driving her partner’s electric car.
“We try to be very conscious about what we’re buying,” she said.
“If a car gives you a good experience driving it, plus it’s environmentally friendly … it’s really important.”
However, Ms Caudillo said she had initially been unaware that electric vehicle batteries could be reused or repurposed after reaching the end of their automotive life.
“Knowing myself that I’m buying something that can be re-used in the future … I’m feeling happy,” she said.
“I feel like that knowledge should be out there [for EV users].”
EV Batteries Present More Complex Recycling Task
Most modern electric vehicles use lithium-iron phosphate (LFP) or nickel-manganese-cobalt (NMC) batteries, while conventional petrol and diesel vehicles typically rely on lead-acid batteries.
Automotive batteries should not be disposed of in landfill and require specialist handling. However, EV batteries are considerably larger and more complex than traditional lead-acid units, making their recycling process more challenging.
Existing Recycling Programs Have Limitations
Queensland motoring organisation RACQ operates a free statewide recycling program, although electric vehicle batteries are not currently accepted.
RACQ executive manager of public policy Dr Micheal Kane said the organisation collects several other types of batteries for recycling.
“RACQ collects [for] recycling low voltage automotive, marine, and deep cycle batteries … through our network of RACQ Assistance and auto stores,” he said.
Specialist recycling companies are instead developing processes designed specifically for lithium-ion technology.
Melbourne-based Envirostream collects end-of-life lithium-ion batteries from across Australia and transports them to its facility, where they are safely discharged.
Large battery packs are dismantled into smaller components, allowing critical minerals and other valuable materials to be recovered. Those materials are then sent to partner companies for further refining and can eventually be used in new batteries and other products.
Safety Becomes a Major Consideration
Envirostream chief executive Simon Linge said EV batteries require particularly careful handling because of their size and higher energy density.
“Lead acid batteries typically [weigh] 15-20kgs a piece, an EV battery [ranges] from 300 to 700 kilos in weight,” he said.
“Both are dangerous and hazardous goods; both can have fires, but a lithium-ion battery fire holds a lot more energy and therefore is a much bigger fire … so it’s why in our operation safety is paramount.”
The difference means recycling facilities need appropriate safety systems, equipment and trained workers capable of handling large lithium-ion battery packs.
Australia Needs Greater Domestic Recycling Capacity
Mr Linge said processing more used EV batteries within Australia could help retain valuable materials while supporting domestic capabilities in battery recycling and resource recovery.
“We have the opportunity, by recycling these batteries, for Australia to play its part at building our own sovereign capabilities of capturing these materials … and reformatting those materials into other applications.”
Recovering materials from old EV batteries could become increasingly important as demand for critical minerals grows across electric transport, renewable energy and battery storage industries.
Specialist Skills Will Be Needed
University of Queensland lecturer Dr Kai Li Lim, from the School of Electrical Engineering and Computer Science, said Australia’s EV battery management sector was “not yet” keeping pace with the growth of electric vehicle use.
However, he expects recycling capacity to expand before large numbers of the current generation of EVs reach the end of their useful lives.
“I think quite confidently that they will expand in time for when EVs need to be recycled … the question is how do we prepare for it?” he said.
“I think what needs to happen is the training of skills here in this country … so they will train people to be able to handle [electric vehicle] batteries and to recycle [electric vehicle] batteries.”
“I am quite confident that [Australia] will be able to get to that stage … but not just Australia … there will be demand globally.”
As EV ownership continues to increase across Australia, managing batteries beyond their years on the road will become an increasingly important part of the transition. Expanding specialist recycling facilities, developing a skilled workforce and improving consumer knowledge will be central to ensuring valuable battery materials can be safely recovered and reused.
