The Battery Nobody Will Take

On a shelf at a salvage yard sits a Tesla battery that still works.

As a spare part, it's priced at $1,200. Inside are lithium, nickel, cobalt, and copper, the metals every battery maker on earth is scrambling for. A nickel-rich pack like this can hold roughly $2,500 of recoverable metal. The only recycler willing to take it quoted negative $1,800. That isn't a payment to the yard. It's a bill.

"No one's paying me for it. I have to pay to get rid of it," the yard owner told NPR. So how does something full of valuable metal end up with a negative price?

The metal is valuable. Moving it isn't.

A dead lithium battery is legally hazardous material. It needs special packaging, certification, and a qualified carrier. That cost barely changes whether the pack holds $500 of metal or $3,000. You pay per shipment, not per dollar inside.

Here's the tell. If the yard could bundle five packs like this one, a recycler might take them for free. One pack costs $1,800 to get rid of. Five cost nothing. The metal didn't change. The logistics did.

Then there's what's inside. A growing share of EVs run on lithium iron phosphate, or LFP. That chemistry is cheap precisely because it skips nickel and cobalt, which is great for car buyers and terrible for recyclers. A major U.S. recycler's CEO says there's essentially no value in recycling it. In North America, recyclers charge around $1.50–$2 per kilogram just to accept LFP, and Large EV battery packs can weigh a ton or more.

For those packs, "free" isn't even on the table.

The pack fights back.

Even when the metal is worth recovering, someone has to get to it.

A modern pack is thousands of cells sealed in structural adhesive and hard-set foam, joined by welded metal strips instead of bolts. That's deliberate. A cell that shorts against its neighbor can start a fire that feeds itself. So engineers build packs where nothing moves, nothing touches, and nothing comes loose.

That design works beautifully for fifteen years. Then it becomes a problem.

When Munro & Associates tore down Tesla's structural 4680 pack, they rated its repairability essentially zero. Opening it took two days, and they blasted the foam off the cells with dry ice.

The work is also dangerous. Packs sit at 400 to 800 volts. Technicians wear insulated gloves and arc-rated clothing and watch for swelling or a sweet chemical smell, both warning signs of runaway overheating. One disassembly founder says a good day is three packs.

So the metal is valuable, the shipping cost is fixed, and the packs fight back. The obvious fix is to build giant plants and win on volume. The industry tried exactly that.

The wave that didn't come.

For a decade, battery recycling ran on one forecast. A flood of dead EV batteries was coming, and whoever owned the plants would own the flood. Billions were raised against it.

The flood hasn't come. The IEA says global recycling capacity is currently largely in excess of available feedstock. Most recycling feedstock today comes from battery manufacturing scrap, not old cars. There's a roughly 15-year lag between an EV being sold and its battery becoming available to recycle. End-of-life packs aren't expected to take the lead until the mid-2030s.

The reason is almost charming: the batteries are lasting.

A UK analysis of more than 8,000 battery-health assessments found that eight- to nine-year-old EVs still retained a median 85% of their original capacity. In other words, battery degradation often isn't what ends the vehicle's useful life.

The cars are dying before the batteries.

That's wonderful news for drivers. For recyclers that built ahead of the expected flood, it made an already difficult business even harder.

Li-Cycle, once one of North America's most prominent battery recyclers, entered creditor protection in May 2025. Glencore acquired much of its business and assets that August.

Ascend Elements, once valued at $1.5 billion, filed for Chapter 11 in April 2026. In August, a judge approved its liquidation plan.

Meanwhile, one recycler is raising money instead of losing it. Its big bet involves not taking batteries apart.

The battery may be worth more intact.

Redwood Materials, founded by Tesla co-founder and former CTO JB Straubel, noticed what the rest of the industry was learning the hard way. Many packs arriving at its door were still healthy.

So instead of shredding them, Redwood wires old EV batteries that aren't ready for recycling into energy storage systems. Its first, a 63 MWh system, supplies a Crusoe data center in Nevada. In January, Redwood closed a $425 million round, with Google joining, at a reported valuation above $6 billion.

Think back to how the packs were built: glued, foamed, and welded shut so they would never come apart. That made them miserable to recycle.

It also made them sealed, self-contained energy storage units.

The packs that were too expensive to open turned out to be worth something exactly as they are.

This doesn't solve recycling, since every one of those batteries gets shredded eventually. But it buys time. Maybe enough time to reach the mid-2030s, when the wave finally arrives and whichever plants are still standing get their feedstock.
