A two-for-one deal—they get the lithium and the phosphate
As the world's appetite for cleaner transport accelerates, Australia finds itself at a crossroads between raw material exporter and strategic processor. Pilbara Minerals and Calix have joined forces to transform low-grade spodumene into a high-concentration lithium compound purpose-built for the LFP batteries now powering the majority of electric vehicles sold in Australia and nearly half of those sold globally. Backed by $20 million in federal funding, the partnership asks a deeper question about national identity in the energy transition: will Australia remain a quarry for others, or become an architect of the technologies that will define the next century of mobility?
- Australia's EV market is outpacing the world, with LFP batteries already claiming 60% of local sales — creating urgent pressure on domestic miners to move beyond raw exports.
- The old model — shipping spodumene at 5-6% lithium concentration, laden with waste minerals — is becoming economically and environmentally indefensible as global battery supply chains tighten.
- Pilbara Minerals and Calix are deploying a phosphate-based kiln process powered by renewables to concentrate lithium to 38%, slashing transport emissions and delivering battery makers two key LFP ingredients at once.
- A $20 million federal commitment signals government confidence, but the real test lies ahead — whether Tesla, Ford, Rivian, and others will choose Australian-processed lithium over entrenched suppliers.
- For Calix, long defined by ambitious but low-revenue moonshots, this partnership represents the first clear path to meaningful commercial scale.
Australia's electric vehicle market is accelerating ahead of the global curve, and the country's miners are now racing to keep pace. Pilbara Minerals and ASX-listed technology company Calix have formed a partnership to produce a new form of lithium engineered specifically for LFP batteries — the chemistry now found in more than 60% of EVs sold in Australia, including the Tesla Model 3, Tesla Model Y, BYD Atto 3, and MG ZS. The federal government has committed $20 million to the venture through its modern manufacturing initiative, wagering that advanced processing capability can anchor a domestic battery supply chain.
The innovation at the heart of the partnership is a kiln system Calix originally developed to decarbonise cement, steel, and alumina production. Applied to lithium, it uses a phosphate-based reagent and renewable energy to strip away the waste minerals — silica, alumina — that make up the bulk of traditional spodumene concentrate. What remains is a compound with roughly 38% lithium by weight, compared to the 5-6% in conventional exports. The resulting material bonds lithium to phosphorus, meaning battery manufacturers receive two of the three core ingredients for LFP cathodes already combined — reducing shipping volumes, cutting transport emissions, and streamlining production.
The timing reflects a seismic shift in battery chemistry. In 2021, LFP technology accounted for just 22% of global EV sales. By mid-2023, that share had risen to 42%. The drivers are straightforward: LFP batteries cost roughly 20% less than NMC alternatives and avoid cobalt, a mineral whose supply chain carries persistent ethical concerns tied to mining conditions in the Democratic Republic of Congo. Consumers like Mario Silvera, a BYD Atto 3 owner in Sydney, have found the practical trade-offs negligible — his car delivers over 400 kilometres per charge, handles long regional drives comfortably, and offered him a cleaner conscience alongside a lower price.
The global momentum is unmistakable. Tesla is expanding LFP adoption across standard-range models in the US and Europe. Ford is rolling out an LFP version of the Mach-E and plans to bring the technology to the F-150. Rivian is expected to follow later this year. Even European manufacturers, traditionally slower to pivot, are moving: Volvo's entry-level EX30 will ship with LFP batteries.
For Calix, the Pilbara partnership marks a turning point after years of pursuing what its chief executive Phil Hodgson describes as decarbonisation-themed moonshots — bold technological bets that have so far yielded only modest revenue. Hodgson has said the lithium project is the first with a clear line of sight to significant commercial returns. For Pilbara, it reflects a broader push into higher-margin products, including lithium sulfate and technical-grade lithium carbonate. The Productivity Commission recently affirmed the underlying logic: Australia's edge lies in processing critical minerals, not in manufacturing finished batteries.
Whether the partnership fulfils its promise will depend on whether global automakers, now firmly committed to LFP chemistry, choose to source their lithium compounds from Australia rather than from established suppliers. The next few years will determine whether this moment of alignment between technology, policy, and market demand can be converted into lasting strategic advantage.
Australia's electric vehicle market is moving faster than the world's, and now the country's miners are moving to match that pace. Pilbara Minerals and Calix, a technology company listed on the ASX, have formed a partnership to create a new form of lithium tailored specifically for the batteries that are rapidly becoming the standard in Australian cars. The federal government has already committed $20 million to the project through its modern manufacturing initiative, betting that this processing capability will anchor a domestic battery supply chain.
The partnership adapts technology Calix has already pioneered in heavy industry—its kiln system has become a global tool for decarbonizing cement, steel, and alumina production. Now that same innovation will be applied to lithium. The result is a product with a fundamentally different character than what Australian miners have traditionally sold. For decades, Pilbara and its peers have shipped spodumene concentrate, a raw material containing only 5 to 6 percent lithium mixed with waste minerals like silica and alumina. The new process, powered by renewable energy, uses a phosphate-based reagent to strip away those waste products and concentrate the lithium to roughly 38 percent of the final product's weight. What emerges is lithium bonded to phosphorus—a compound that carries three distinct advantages. It requires far less trucking and shipping to move the same quantity of lithium across oceans. It produces less carbon in transit. And it arrives at battery makers' doors already containing two of the three key ingredients they need for LFP cathodes: the lithium and the phosphate.
LFP batteries—lithium iron phosphate chemistry—have moved from a niche product to the dominant form of electric vehicle battery in a remarkably short time. Five years ago, in 2021, just 22 percent of electric vehicles sold globally used LFP technology. By May of this year, that figure had climbed to 42 percent. Australia has moved even faster. More than 60 percent of electric vehicles sold in the country this year contain an LFP battery. Four of Australia's best-selling models—the Tesla Model 3, Tesla Model Y, BYD Atto 3, and MG ZS—all use LFP chemistry, and all are imported from China. The shift reflects two powerful forces: LFP batteries cost roughly 20 percent less than their NMC counterparts, and they avoid cobalt, a mineral whose supply chain raises persistent ethical concerns because most of the world's cobalt comes from the Democratic Republic of Congo.
Mario Silvera, who drives a BYD Atto 3, represents the kind of consumer now choosing LFP. He had worried that the cheaper battery chemistry might mean sacrificing performance or range. After seven months of ownership, he reports the opposite. His car delivers more than 400 kilometers on a full charge even with the air conditioner running, and he has made long drives from Sydney to Jervis Bay without difficulty. He has also driven vehicles with NMC batteries—a Nissan Leaf and a Hyundai Kona—and found the practical differences negligible. For him, the ethical dimension of avoiding cobalt mattered as much as the price.
The global trend is accelerating. Tesla has begun importing LFP batteries to the United States and Europe for standard-range versions of its vehicles. Ford is manufacturing an LFP version of the Mach-E and plans to expand the technology to the F-150 next year. Rivian is moving toward LFP adoption later this year. European manufacturers are moving more slowly, constrained by longer decision timelines and legacy supply chains, but even there the shift is underway. Volvo's entry-level EX30 model will ship with LFP batteries, and the company expects to expand LFP across its range. Chinese-owned European brands like MG will likely move faster.
For Calix, the Pilbara partnership represents a turning point. The company has spent years pursuing what its chief executive Phil Hodgson calls "decarbonisation themed moonshots"—ambitious bets on technology that could reshape heavy industry. Until now, those efforts have generated only modest revenue from a water treatment service. Hodgson said the lithium project is "clearly our first project that has line of sight to significant revenues." For Pilbara, the move into value-added processing reflects a broader strategy. The company is exploring other higher-margin lithium products as well: lithium sulfate, technical-grade lithium carbonate, and others still in development. The shift acknowledges a reality the Productivity Commission flagged last month—Australia's competitive advantage lies not in manufacturing finished batteries but in processing the raw materials that go into them.
The $20 million in government funding signals confidence in that strategy. Pilbara's leadership welcomed the support while making clear they would welcome more. The partnership sits at the intersection of three policy priorities: fostering domestic processing of critical minerals, reducing the carbon footprint of battery supply chains, and building the infrastructure for local battery manufacturing. Whether it succeeds will depend partly on whether global automakers, now committed to LFP chemistry, choose to source their lithium compounds from Australia rather than from established suppliers elsewhere. The next few years will show whether this partnership can capture that opportunity.

As it relates to LFP cathode makers, they are chasing all three and this is a two-for-one deal, they are getting the lithium and the phosphate— Pilbara Minerals leadership

Why does it matter that Pilbara is making a more concentrated lithium product? Isn't lithium lithium?
Not quite. When you ship spodumene concentrate across the ocean, you're paying to move a lot of waste—silica, alumina—that the battery maker will just throw away. The new product is 38 percent lithium instead of 5 or 6 percent. Same amount of usable lithium, but a fraction of the weight and volume. That cuts shipping costs and carbon emissions both.
And the phosphate bonding—that's the clever bit?
Exactly. LFP battery makers need lithium, iron, and phosphate. This product delivers two of those three. It's like showing up to a construction site with half the materials already mixed and ready. Saves them a step, saves them money.
Why is LFP suddenly everywhere in Australia when it wasn't five years ago?
Two reasons, really. It's cheaper—about 20 percent less than the alternative chemistry. And it doesn't use cobalt, which most of the world sources from one country with serious ethical concerns. Once Tesla and BYD started shipping LFP vehicles here, Australian buyers realized they weren't sacrificing anything. Range is fine, performance is fine. The price difference became the deciding factor.
Is Australia actually going to build batteries, or just process the raw materials?
That's the honest answer: probably just process them. The Productivity Commission basically said Australia's advantage is in refining low-concentration minerals, not in full battery manufacturing. This partnership is betting that if you can deliver a superior intermediate product—something closer to finished—you can still capture real value and keep the work onshore.
What happens if car makers decide to source their lithium elsewhere?
Then the whole strategy falters. But the timing is interesting. Global automakers are committing to LFP right now. If Pilbara and Calix can prove they can deliver a product that's cheaper and better than what's available elsewhere, they're positioned to capture that wave. It's a narrow window.
