In the context of the energy transition and the necessary use of rechargeable battery storage systems, solid-state batteries offer great potential due to their potentially higher energy and power density and safety compared to conventional lithium-ion batteries. To address the rapidly increasing demand for primary materials and potential material shortages, tailor-made recycling processes for the different types of solid-state batteries need to be developed. The publication in the journal “Nature Energy<\/a>” presents possible solutions for recycling the different types of solid-state batteries.<\/strong><\/p>\n

Due to the very different material-specific properties of the different solid-state batteries, different process routes are required. One possible solution to this problem is a multi-way, multi-product recycling plant that combines different routes to achieve maximum flexibility with regard to the input battery material.<\/p>\n

The review, published in the renowned journal “Nature Energy”, focuses specifically on current recycling strategies for various solid-state batteries (SSBs). The focus is on promising solid electrolytes (SEs), including oxides, sulphides\/thiophosphates\/halides and polymers, as well as combinations of these (so-called hybrid solid electrolytes). The fundamental knowledge for these recycling strategies is being developed through ongoing research at the Battery LabFactory (BLB).<\/p>\n

“Due to the different physical and chemical properties of the solid electrolytes mentioned, we are considering adapted recycling routes that include pre-treatment as well as mechanical, hydro- and pyrometallurgical processes,” says Prof. Arno Kwade, head of the Institute of Particle Technology and spokesperson of the Battery LabFactory Braunschweig (BLB).<\/p>\n

Against this background, the Braunschweig scientists believe that a reusable and multi-product recycling plant, which can recycle as many different cell chemistries and solid-state battery types as possible, is the most promising solution for the future. This includes other next-generation batteries such as lithium-sulphur and sodium solid-state batteries.<\/p>\n

“We also consider the further development of direct regeneration processes (so-called direct recycling) for cathode active materials and solid-state electrolytes to be necessary and very important in order to achieve higher recycling rates and minimise negative environmental impacts,” continues Prof. Kwade.<\/p>\n

In order to develop these solutions, the researchers carried out a qualitative analysis of the current research situation<\/strong> in the field of SSB recycling and also drew on extensive experience and knowledge in the field of lithium-ion battery recycling (such as the lighthouse projects LithoRec I and II and the BMBF cluster greenBatt) as well as the manufacture and production of solid-state electrolytes and batteries as part of the excellence cluster “S\u00b2EA – Sustainable and Energy Efficient Aviation” and the BMBF cluster FestBatt.<\/p>\n

The conclusions and recommendations presented in the publication are highly relevant for decision-makers in industry, science and politics. For example, the introduction of the so-called battery passport and legally defined recycling quotas for the material compounds and elements specifically used in solid-state batteries can create the prerequisites for implementing the necessary circular economy<\/strong> and the circular production of highly integrated products. At the same time, the tailor-made recycling routes can help to reduce the need for primary materials<\/strong> for critical materials and raw materials due to very high recycling rates, thereby also reducing dependence on third countries<\/strong>. For the scientific community, questions and possible process options and directions to be investigated are proposed that are promising for the recycling of solid-state batteries and their materials.<\/p>\n","protected":false},"excerpt":{"rendered":"
