EV Battery Recycling Guide

Yes, electric vehicle batteries are 95% recyclable. We recover lithium, cobalt, and nickel using hydrometallurgical processes. This guide explains how we handle high-voltage batteries safely and your legal obligations in 2026.

The Challenge

Why You Can't Bin an EV Battery

By 2030, the sale of new petrol and diesel cars will stop in the UK. This means millions of Electric Vehicles (EVs) will eventually reach the end of their life. Unlike standard car batteries, EV packs operate at 400V to 800V.

If you damage these cells, they can enter Thermal Runaway—a chemical fire that burns at 1,000°C and cannot be put out with water. That is why only certified Authorised Treatment Facilities (like ours) can legally dismantle them.

  • Our Process

How We Recycle EVs

1

High Voltage Disconnect

Before any physical work begins, certified High Voltage (HV) technicians isolate the battery pack from the vehicle chassis. Using specialized insulated tools and PPE, they engage the ‘Service Disconnect’ plug and verify zero voltage potential across the busbars.

2

State of Health (SoH) Diagnostics

Not all batteries need to be shredded. We connect diagnostic computers to the Battery Management System (BMS) to read the cell voltages. If the battery retains >70% capacity, it is earmarked for ‘Second Life’ applications. If <70%, it moves to recycling.

3

Discharge & Dismantling

Recycling candidates are deep-discharged to 0V using salt-water baths or resistive load banks. This removes all stored energy, making the pack safe to open. Modules are then separated from the cooling systems, wiring harnesses, and aluminium casings.

4

Black Mass Recovery

Modules are shredded in an inert atmosphere (nitrogen) to prevent combustion. The output is sorted into plastics, copper, and ‘Black Mass’—a powder containing the active materials (Lithium, Cobalt, Nickel). This is sold to chemical refiners to build new batteries.

Second Life Energy

When an EV battery drops below 70-80% capacity, it creates "range anxiety" for drivers. However, it still holds massive amounts of energy—enough to power a home for days.

We partner with energy firms to repurpose these packs into Grid Support Systems. These "zombie batteries" store solar power during the day to run homes at night, extending the battery's life by another 10-15 years.

Thermal Runaway

If a Li-ion cell is punctured, the separator between the anode and cathode fails. This causes an internal short circuit, generating heat (over 1,000°C) in milliseconds.

This is why you must NEVER attempt to dismantle an EV yourself. We use thermal imaging cameras and quarantine containers filled with vermiculite to manage damaged packs safely.

  • FAQ

Can I sell a used EV battery?

Yes, but only as part of the whole vehicle. Removing a battery yourself is dangerous and devalues the car. We pay for the lithium content as part of the total scrap price.

Do you accept hybrid batteries (NiMH)?

Yes. Toyota Prius and older hybrids use Nickel-Metal Hydride (NiMH). We accept and process these differently to Li-ion, but we handle both types at our ATFs.

Is it illegal to put a car battery in a skip?

Absolutely. It is a criminal offense in the UK. Lead-acid and Li-ion batteries are classified as Hazardous Waste. They must be collected by a licensed carrier like us.

What is Black Mass?

Black Mass is the crushed powder left after shredding a battery. It contains valuable metals like Lithium, Cobalt, and Nickel, which are refined to make new batteries.
