What Happens to Batteries from Scrapped Electric Vehicles?
6th Aug, 2025
You bought an electric car to do your bit for a cleaner future. So when it finally gives up the ghost, the last thing you want is for its most important part, that giant battery, to end up as a problem for the planet. So, what actually happens to batteries from scrapped electric vehicles?
It’s a great question, and the answer is a lot more interesting than just a trip to the crusher. An old EV battery isn’t just a piece of rubbish; it’s a box full of power and valuable stuff. Its journey after the car is scrapped is a pretty amazing story of recycling and getting a second chance.
Getting this right is the final piece of the puzzle in making electric cars truly sustainable. At Scrap Car Network, we make sure to work with specialist partners who are experts in this, ensuring every battery is handled safely and properly.
The First Stop: The End of the Road (For the Car)
So, what kicks off this whole journey? It all starts the moment an electric car is officially taken off the road. This might be because the battery has faded and won’t hold a decent charge, or maybe a fault or an accident has left it with a repair bill that just doesn’t make sense.
The car is taken to a licensed Authorised Treatment Facility (ATF), where it’s first “depolluted.” This means all the fluids are drained out and the tyres are removed. Then comes the most important and tricky part: a specialist has to safely disconnect and remove the high-voltage battery pack. This is not a job for an amateur; it requires proper training and insulated tools to avoid the risk of a nasty electric shock.
Once that battery is out, the car’s empty shell is just like any other it gets crushed and its metal is recycled. The battery, though, is about to start a whole new adventure.
The Big Decision: A Second Life or Back to Basics?
An old EV battery arrives at a specialist facility where it faces a big decision. Think of it like a solid old bit of furniture. Is it still good enough to be cleaned up and used in another room, or is it time to break it down for firewood?
For EV scrapped batteries, the two paths are:
- A “Second Life”: If the battery can still hold a decent amount of charge (usually around 70-80% of what it could when new), it’s far too valuable to be destroyed. It can be refurbished and given a brand new job.
- Full Recycling: If the battery is too old, damaged, or faded, it’s sent to be completely broken down to get the precious raw materials out from inside.
A New Beginning: The Battery’s Second Life
This is where things get really clever. A battery that can no longer push a heavy car down the motorway is still perfectly capable of powering other things for years to come.
These “second-life” batteries are becoming a huge deal for energy storage. They are grouped together in large banks and used for all sorts of things:
- Powering Homes: A bank of old car batteries can be hooked up to solar panels. They store free electricity during the day and then power your house at night.
- Keeping Events Running: Instead of noisy, smelly diesel generators, music festivals and outdoor events can be powered by silent, clean, second-life batteries.
- Providing Backup Power: Hospitals, data centres, and even mobile phone masts use them as a backup to keep everything running if there’s a power cut.
This can give a battery another 10 to 15 years of useful life, which is a massive win for the environment.
The Final Breakdown: Recovering the Treasure
When a battery is truly at the end of the line, it’s time to recover the valuable materials locked inside. This is a highly scientific process, more like a high-tech mining operation than a scrapyard.
The main goal of the EV battery disposal and recycling process is to get back:
- Lithium and Cobalt: The most valuable and sought-after ingredients.
- Nickel, Manganese, and Graphite: Other key materials for new batteries.
- Copper and Aluminium: From all the wiring and the casing.
There are a few ways to do it, but it usually involves shredding the battery parts and then using liquids or heat to separate the different metals. The best processes can recover over 95% of the key materials. These are then sold back to battery makers to create a closed-loop system. This “urban mining” means we don’t have to rely so much on digging new holes in the ground all over the world.
