Electrical automobiles want batteries. Batteries want cathodes. Australian mining wants to maneuver up the worth chain. All these wants will likely be met by the institution of Avenira’s LFP cathode manufacturing plant in Darwin, in Australia’s Northern Territory. The cathode manufacturing plant will likely be linked to Avenira’s Wonarah phosphate venture 1010 km away by street. The closest settlement is the village of Camooweal 190 km away with a inhabitants of 240 folks. Operations in each Wonarah and Darwin will likely be powered by a mix of photo voltaic, wind, and gasoline.
The phosphate mined can be utilized to fabricate lithium-ferro-phosphate (LFP) batteries, LFP cathodes, and fertilizer. It’s anticipated that inside two years, Avenira may very well be considered one of solely three LFP cathode producers exterior of China, giving world EV producers extra provide and extra alternative of provider of battery grade materials. Avenira hopes to start building on the LFP plant late subsequent yr, with LFP cathode manufacturing to start in 2025.
However why LFP batteries?
“After Tesla, many main automobile producers on this planet, comparable to Volkswagen, Ford, Stellantis, Mercedes and BMW, introduced that they’d be shifting commonplace vary automobiles to LFP batteries. One of many causes for this was the predominance of EV battery fires in NCM (nickel cobalt manganese) battery EVs. NCM batteries, have thermal stability issues and have to be cooled, in contrast to LFP batteries,” Brett Clark, Avenira’s chair and chief government officer, defined.
The Northern Territory authorities says that this venture has the potential to create 1,000 jobs in mining and manufacturing within the territory. This backs up its declare that the Northern Territory is open for enterprise. Roughly $4 billion in income ought to move into the Australian economic system.
Some EV producers are phasing out using NCM batteries, notably for decrease vary automobiles and private transportation units like e-scooters and e-bikes. The brand new technology of LFP batteries are catching as much as their extra vitality dense NCM cousins. There are different benefits, too.
“From an ESG (environmental, social and governance) perspective, LFP batteries are extra recyclable — you’re not recycling cobalt, nickel, and different poisonous supplies,” Clark mentioned. “They’re additionally cheaper to fabricate and so they produce other recharging properties which suggests you will get about 30% to 40% extra recharge cycles from them in comparison with conventional NCM batteries.”
The matter of them being cheaper can also have a big function of their market development.
Because the rEVolution gathers tempo, there may be loads of room to develop. Avenira is anticipated to make the ultimate funding choice on the Wonarah venture subsequent quarter, then transfer to a trial section of mining. Avenira will goal to ramp up the availability of battery-grade LFP manufacturing as quickly as attainable.
Avenira plans to ship the phosphate by prepare, every prepare carrying 10,000 tons — beginning with one prepare after which growing to three, relying on demand. Avenira’s CEO is searching for efficiencies in building and commissioning of the trains. Efficiencies will be achieved by onshoring mining and downstream processing practices. This equates to fewer transport and logistical prices, making its built-in LFP provide chain extra economical.
Avenira has partnered with Taiwanese battery materials pioneer Aleees. The Darwin LFP plant replicates Aleees’ working LFP battery cathode materials plant in Taiwan. This partnership reduces the danger to Avenira. “This MOU opens the door for Avenira to study from Aleees about LFP battery cathode manufacturing expertise. We are able to leverage this expertise to optimise the manufacturing of phosphoric acid from the Wonarah Mission and develop downstream belongings to provide Australia’s first LFP precursor cathode materials,” Clarke mentioned.
“Whereas DSO manufacturing is happening at Wonarah, and Avenira is producing first cashflow, the corporate will work alongside Aleees to advance the LFP plant in Darwin. Having achieved DSO manufacturing from Wonarah and first LFP cathode manufacturing from its Darwin plant, Avenira will then goal to provide a thermal phosphoric acid product from an extra processing facility at Wonarah.
“This midstream product will then be used as feedstock for the Darwin LFP plant. Previous to the thermal phosphoric acid plant coming on-line, Avenira would supply thermal phosphoric acid from Aleees’ present provide chains to feed the Darwin facility.”
Aleees was based in 2005, with its principal workplace and manufacturing facility situated in Taiwan. It’s a lithium-iron phosphate (LFP) battery materials producer. It is without doubt one of the few firms exterior China with full LFP battery materials manufacturing expertise and patents. Additionally observe that Aleees Taiwan owns greater than 120 unique patents worldwide.
“Previous to 2015, Aleees had been the biggest LFP cathode materials producer globally,” Clark mentioned. “However China has moved forward massively round LFP cathode manufacturing since then by way of a whole lot of subsidies and low-entry prices from a capex (capital expenditure) viewpoint.”

The enhancement of green-energy, high-tech growth within the metropolis continues to be promising. “One of the thrilling alternatives created by renewable vitality applied sciences like cathode supplies is the flexibility to vary the world’s sustainability,” says Brandon Chang, head of the Aleees’ Australian arm.
“The important thing factor for us as an organization is to make a value-added product,” Clark mentioned. “This begins off with direct transport ore, earlier than shifting to an LFP cathode manufacturing facility in Darwin. Then we construct out our phosphoric acid course of as nicely. So we’re targeted on integrating downstream manufacturing and dealing in supplies which are going to be in steady and rising demand in ex-China provide chains.”
Clark additionally famous that Darwin is near key export markets and has core transportation infrastructure, like ports and rail connections, in place. Darwin to Taiwan is sort of the identical distance as Darwin to Canberra, Australia’s nationwide capital (4160 km and 3934 km respectively.)
“The view that we’re getting from the worldwide markets is that cathode materials ought to be manufactured near upstream supplies, whereas battery cell producers ought to be near the electrical automobiles and vitality storage system producers,” Clark mentioned.
The stress between China and the USA in addition to the Russian invasion of Ukraine have highlighted the necessity for diversification of provide of supplies important for the rEVolution. Constructing a vertically-integrated LFP operation is actually a sensible transfer for Avenira and useful for Australia’s inexperienced transition additionally.

Right here at CleanTechnica, we carried out a restricted paywall for some time, nevertheless it at all times felt fallacious — and it was at all times powerful to determine what we should always put behind there.

Sadly, the media enterprise continues to be a troublesome, cut-throat enterprise with tiny margins. It is a endless Olympic problem to remain above water and even maybe — gasp — develop. So …
