Our Innovations

At BASF, we love electric vehicles – and that’s exactly why we’re driven to make them even more sustainable. Find out how we are improving the carbon footprint of EVs by focusing on the all-important battery materials, from sourcing to production to recycling.

Sourcing

Loving EVs means respecting our sources

At BASF we know that the way metals are sourced for electric vehicle (EV) battery materials is a crucial factor in the very sustainability of EVs themselves.

That’s why, together with our partners, local mining cooperatives, and government authorities, we’ve embraced a series of global initiatives to improve working conditions for miners. We’re a founding member of the Global Battery Alliance (GBA). The GBA is dedicated to fostering sustainable and responsible supply chains that both generate sustainable employment and help to achieve the goals set by the Paris Climate Agreement.

Metals such as nickel and cobalt are essential to support strong growth in the global EV value chain and we work to manage the impact of sourcing these metals in the best possible way. Each supply chain is assessed for sustainability and we strive to ensure that environmental, social and human rights standards are respected. Where additional governance is needed, supply chains are covered by comprehensive third-party certification, such as the Initiative for Responsible Mining Assurance scheme, which is co-governed by NGOs, industry, communities and labor unions.

Production

Love EVs. Don’t love carbon footprint.

Producing EV battery materials can take a lot of energy. We’re reducing the CO₂ footprint by using more energy-efficient processes, more renewable energy and shorter transportation routes.

Thanks to our innovative production plants for precursors in Harjavalta, Finland and cathode active materials in Schwarzheide, Germany, we are manufacturing cathode active materials in a way that reduces the carbon footprint by up to 40% compared to the industry benchmark.

BASF will be the first cathode active materials supplier with production capacity in all major markets. Cathode active materials are the chemicals that help “power” the batteries of electric vehicles. Because we have production assets and R&D teams in all the main markets, including Asia, Europe and North America, we can support our customers with tailor-made solutions ready to meet the requirements of local governments and respond to the global demand for electric vehicles. In fact, in a recent development, BASF and Shanshan – a leading lithium-ion battery materials supplier – have formed a joint venture serving the world’s largest battery materials market, China.

Recycling

Metals we can’t bear to part with

Together with our partners, we’re working on innovative ways to make sure the essential metals needed to keep your electric vehicle’s wheels turning are here to stay.

More and more electric cars are registered worldwide every year. At the same time, the raw materials for the batteries are limited and their mining is associated with negative environmental impact. BASF researchers at the Ludwigshafen site therefore develop a new chemical process to recycle the lithium contained in the battery in high purity. This will also avoid waste and reduce the CO2 footprint compared to state-of-the-art recycling processes. During the production of the so-called "black mass", metallic fractions are separated. These include aluminum foils on which the cathode active material was applied. Different mechanical processing steps lead to either coarse or fine metal fractions, which can also be recycled afterwards.

The innovative recycling process we use recovers valuable metals extracted from phased-out EV batteries and battery production scrap at a world-leading rate. By recycling these metals, we are able to save primary resources as well as reduce CO₂ emissions.

We’re building a new prototype battery recycling plant at Schwarzheide in Germany that can extract a range of essential metals such as lithium, cobalt and manganese, bringing them back to life for use in new batteries. It’s a huge step in closing the loop when it comes to creating more sustainable electric vehicles.

Research

It's a passion project

We’re always testing novel materials, innovative recycling solutions and leading process technologies to improve our CO₂ footprint. We’ll leave no stone unturned in making EV battery materials even more sustainable.

Tiny particles of advanced cathode materials for batteries.

BASF is developing advanced cathode materials for batteries, which consist of tiny particles that are just micrometers in size.

Our global R&D teams work tirelessly to improve the performance of battery materials. Their advances are aimed at helping the real driving range of a typical midsize car jump to 600km, while reducing the charging time to 15 minutes.

We’re also researching how cobalt can be removed from electric vehicle batteries, or at least dramatically reduced. To that end, we’re exploring how cutting-edge lab research can be scaled up to production level.

In addition to R&D on cathode active materials for lithium-ion batteries, we are working on components for next-generation batteries. These include solid-state batteries in which the electrolyte is solid rather than liquid and the anode is lithium rather than graphite based. This will bring considerable improvements in safety and will take up less space in the car.

Partnering with universities, academic institutions and private partners, our finger is on the pulse of scientific advances when it comes to promising novel and improved materials. One example of our collaboration network is BELLA (Battery and Electrochemistry Laboratory), a joint laboratory of BASF and the Karlsruhe Institute of Technology in Germany.
