Battery recycling / e-mobility

Innovations are all in a day’s work for us, but there’s one we are especially proud of: Since October 2021, our integrated analysis model for recycling lithium-ion batteries has enabled us to support both recycling and producing companies at all stages of the value chain. That makes us the first and only laboratory in Germany to offer this challenging analysis from a single source. We act as experts overseeing the entire process, from evaluation of the black mass and recovery of valuable materials to further processing into preliminary products for new batteries.

In light of the e-mobility debate in particular, the demand for battery recycling is set to increase significantly. ChemiLytics therefore now offers detailed analysis relating to recycling of lithium-ion batteries. We act as experts overseeing the entire process, from evaluation of the black mass and recovery of valuable materials to further processing into preliminary products for new batteries.

Detailed three-stage analysis in the recycling of lithium-ion batteries

Determination of the chemical and physical properties of preliminary products (e.g. molecular structure or flowability)

*”Black mass” refers to the material produced when a used battery is pretreated for recycling.

Especially for metals such as cobalt, lithium and nickel, primary raw materials may not be able to meet demand. Closed material loops supplement the primary supply and may replace it almost entirely in the foreseeable future – an important contribution to environmental protection and a sustainable economy.

Recycling Recycling companies collect or buy used batteries and dismantle them. With our analytics, we support these companies in precisely and reliably determining the exact content of valuable materials such as lithium, cobalt, nickel, manganese and copper in the black mass. Processing Production Processing Production The metals often have to be separated from each other in several stages in order to make them available again for battery production. In this phase, the accompanying process analysis is particularly crucial in order to check the yield in the individual steps. In the third stage of the value chain, precursors for new battery components are created from the recovered raw materials. Here, we support companies in determining product properties such as purity and phase composition as well as particle size distribution. This enables them to supply reliable products to the manufacturers of the components. Production

Our contribution to the 2029 EU recycling targets

The importance of recycling valuable materials from old batteries is increasingly rapidly, if only due to e-mobility. Estimates suggest that the amount of black mass available in Europe may triple from around 100,000 metric tons per year in 2025 to roughly 300,000 metric tons per year in 2030! Feeding these quantities back into the material cycle to make them available for battery manufacturing is a major challenge! To meet the EU’s ambitious recycling targets for 2029, every market participant along the value chain needs reliable and precise analytics.

Our mission for the future: design for recycling

Until recently, batteries were shredded, burned and treated with acid, which meant the materials could not be separated and the products were not pure enough to be recycled into batteries.

Our mission is to work with battery and automobile manufacturers, suppliers and recycling companies to make closed-loop battery recycling standard practice. There are numerous battery systems on the market, which is why lithium batteries have very different compositions, and on top of this the systems are constantly undergoing further development. Therefore the processes must be designed to deal with many different batteries in order to make their recyclable components available for reuse despite differing compositions.

It is in the manufacturers’ interest to develop future battery systems in a way that makes recycling them as simple and standardized as possible. Finally, in the future more and more raw materials will be processed from recycling, because the resources are finite, especially the rare-earth elements. We follow developments in this area very closely and are continually developing our analysis technology. Our goal in working with our contract partners is not only to support but to revolutionize recycling of lithium-ion batteries.

Our expertise for various markets

As a service provider in the analysis sector, ChemiLytics also offers services tailored to various markets. This means participants in battery recycling, additive manufacturing and recycling as a whole benefit from our expertise in the relevant analysis methods and from our support across entire production cycles and life cycles.
