Eightinks wants to make car batteries recyclable


Schlieren ZH – Eightinks is developing a technology for the mass production of lithium-ion solid-state batteries. In doing so, the start-up places an emphasis on the circular economy. Currently, Eightinks is building its own lab and is also looking for partners.

Lithium-ion solid-state batteries are considered the batteries of the future – especially in electromobility – according to a media release from the Swiss Federal Institute of Technology Zurich(ETH). However, their series production is currently still expensive. In addition, according to ETH data, only 5 percent of batteries are recycled for cost reasons.

Eightinks, an ETH spin-off based in Schlieren, is now working on a manufacturing technology for the mass production of such batteries. The start-up has already patented the process. The cathode and solid electrolyte can be coated in a single pass. In the long term, all functional battery layers could even be applied in just one process step. Overall, the technology helps to reduce production costs and increase quality.

Eightinks continues to aim for a full circular economy in its batteries. To do this, it relies on so-called direct recycling, whereby individual particles are to be extracted directly from the batteries and recycled. The technology required for this is still under development.

At present, Eightinks is still in the start-up phase, according to the statement. Among other things, it is in the process of setting up its own laboratory. In developing its process, it is already cooperating with companies such as TSE Troller or the Bühler Group. However, Eightinks is also interested in material partnerships. ce/ssp
