For most of the electric-vehicle era, the critical-minerals story has been about extraction: more lithium, more nickel, more copper and more processing capacity. Now another source is beginning to matter — the batteries and energy infrastructure already built during the first wave of the transition.
A Reuters analysis published on October 2 highlighted how recycling is starting to return valuable materials to clean-energy supply chains. Modern battery-recycling processes can recover very high shares of lithium, nickel, cobalt and copper, while solar panels, grid equipment and other infrastructure are also becoming sources of secondary materials.
The tempting conclusion is that old batteries can simply replace new mines. They cannot — at least not yet. But the first generation of electric vehicles and large battery systems is creating something that did not exist at scale a decade ago: an expanding above-ground stock of critical minerals that can be recovered and used again.
A battery is not just waste
A lithium-ion battery contains materials that required substantial mining, refining and energy to produce in the first place. When a battery reaches the end of its useful life, throwing those materials away means discarding much of that earlier effort as well.
Recycling usually starts by making the battery safe, dismantling or shredding it and separating components. The resulting material can include a dark powder commonly called black mass, which contains valuable battery minerals. Further processing can then recover metals and salts that can return to manufacturing.
The International Energy Agency says battery-metal recycling is already growing rapidly, although from a low base. It estimates that recycled batteries could eventually supply around 20% to 30% of demand for lithium, nickel and cobalt by 2050 under stronger collection and recycling conditions.
That turns an old battery into something closer to a small ore deposit — except the useful materials have already been mined once.
Australia is trying to keep more of that value at home
Australia has an obvious interest in this shift. It is a major producer of raw battery minerals, but much of the higher-value processing has historically happened overseas.
According to the Australian Renewable Energy Agency, Australia currently exports nearly all of the end-of-life lithium-ion batteries it processes as relatively low-value black mass to China. ARENA says that can mean giving up as much as half of the potential value and associated jobs.
A project in Kewdale, Western Australia, is now testing whether more of that refining can happen domestically. Renewable Metals is developing a commercial prototype that uses hydrometallurgical processing to recover critical minerals from end-of-life batteries. The project is designed to handle different lithium-ion chemistries and eventually process complete electric-vehicle battery packs and battery energy-storage systems.
ARENA says domestic recycling could reduce cell-level emissions by 40% to 50% and battery-cell manufacturing costs by 30% to 50% compared with using virgin materials. Those figures are project estimates rather than a universal result for every recycling process, but they show why battery recycling is increasingly being treated as industrial infrastructure rather than simply waste management.
The big recycling wave is still ahead
There is an important timing problem. Battery deployment has grown much faster than the supply of batteries reaching the end of their lives.
The IEA’s Global EV Outlook 2026 says lithium-ion battery deployment across all applications increased more than sixfold between 2020 and 2025. Electric vehicles and stationary storage account for roughly 90% of today’s lithium-ion battery market.
But most of those batteries are still in use. Some EV batteries will also remain useful longer than expected, either in vehicles or through second-life applications. The IEA estimates that around 1.2 million EV batteries could reach end of life in 2030, rising to about 14 million in 2040.
That is why recycling can become a significant source of minerals without removing the need for new mines in the near term. The same energy transition that creates recyclable batteries is also rapidly increasing demand for the minerals inside them.
The IEA’s 2026 critical-minerals outlook projects that demand for critical minerals almost doubles by 2040 under stated policies, with lithium demand rising more than threefold. Recycling helps reduce the amount of new extraction required, but it is supplying a growing market rather than a static one.
That distinction also matters for Australia’s electricity transition. As renewable electricity reaches new highs, more batteries are being installed to support grids, homes and businesses. Those systems eventually become part of the same future recycling stream.
Not all batteries are equally valuable to recyclers
Battery chemistry complicates the economics. Nickel- and cobalt-rich batteries contain metals with relatively high commodity values, which can make recovery more attractive. Lithium iron phosphate batteries, or LFP, contain no nickel or cobalt and generally carry less recoverable material value.
LFP batteries have become increasingly common in electric vehicles and dominate stationary battery storage. The IEA warns that this shift can make recycling economics more difficult even as the environmental and supply-chain reasons for recycling remain strong.
That means collection rules, producer responsibility, recycling standards and process efficiency are likely to matter just as much as the underlying chemistry. A technically recyclable battery is not much use as a resource if it is never collected or if recovering its materials costs more than they are worth.
Australia’s circular-economy policy is moving in the same direction
The timing also lines up with a broader policy shift. Australia’s environment ministers agreed to a new Circular Economy Roadmap on September 18, 2026.
The roadmap sets a national goal of doubling Australia’s circularity by 2035. It also calls for a 10% reduction in Australia’s material footprint, a 30% increase in material value retained through reuse and the safe recovery of 80% of resources.
Battery recycling fits neatly into that logic. Instead of treating an old battery as the end of a product’s life, it treats the battery as a temporary container for materials that may pass through several generations of products.
The mine is getting bigger
The phrase urban mining can sound like sustainability jargon, but batteries make the idea unusually concrete. A retired EV battery contains a concentrated package of materials that industry already knows it will need again.
The first generation of large-scale battery deployment is only beginning to feed meaningful quantities back into recycling systems. Through the 2030s, that stream should become much larger.
It will not end conventional mining. Fast-growing demand, collection losses, changing battery chemistries and the simple fact that most batteries are still relatively young make that impossible for now.
But the direction is significant. For the first time, part of the material needed to build the next generation of batteries will increasingly come from the previous one.
That makes an old EV battery more than a waste problem. It is becoming part of the critical-minerals supply chain itself.
