Battery Recycling

The Battery Recycling Conference & Expo is an ideal platform for battery manufacturers, recycling companies, and suppliers of critical raw materials to learn about the circular economy for used batteries and how to make supply chains more sustainable. Our battery recycling experts will inform you about the advantages of using hydrogen peroxide in recycling technologies for lithium-ion batteries.

Today, lithium-ion batteries are needed in many areas of everyday life, whether in electric cars, everyday devices, or other electrical machines, and the demand for them is constantly growing. For this reason alone, it is important to recover valuable raw materials from batteries through recycling, thereby enabling a circular economy to conserve resources and protect the climate.

Lithium-ion batteries contain many different precious raw materials such as lithium, cobalt, and nickel, which can be reused in the production of new batteries.

Wet Hydrometallurgy Recycling with Hydogen Peroxide

One of the most widely used LiB recycling technologies is wet hydrometallurgy.

In this process, hydrogen peroxide (H₂O₂) is used as a reducing agent in the

leaching phase to

 

  • oxidize or reduce metals such as Co, Mn, Ni, Li, and Fe to aid their recovery
    from the LiB substrates
  • increase leaching efficiency, and shorten leaching time.

Climate-Neutral Hydrogen Peroxide for Hydrometallurgical Processes

With the supply of our climate-neutral hydrogen peroxide, which is sold in accordance with the “Way to GO2” certificate, we can contribute to reducing the carbon footprint of the hydrometallurgical process.

This is also because, according to the updated Battery Regulation, every industrial or electric vehicle (EV) battery with a capacity of more than 2 kWh that is placed on the EU market must be accompanied by a battery passport.

The battery passport must contain the following information:

HYPROX® hydrogen peroxide to increase leaching efficiency

HYPROX® will contribute to improving the minimum leaching requirements set out in Directive (EU) 2023/1542. Currently, at least 50% of a battery's weight must be recycled. From 2026, this requirement will be increased to 65% for lithium-ion batteries and to 70% from 2031.

Specific recycling requirements for the lithium, cobalt, copper, nickel, and lead content of batteries will also be introduced.

For example, the mandatory recycling rate for lithium will increase from 35% to 70% between 2026 and 2030. The EU is aiming for a recycling rate of 90% for cobalt, copper, nickel, and lead from 2026. HYPROX® will contribute to achieving this goal.
