DECHEMA colloquium on 09 November 2018 at DECHEMA Haus, Frankfurt/Main. The colloquium is supported by the project AutoBattRec of EIT RawMaterials.
Li-Ion batteries are an emerging technology which is incorporated into more and more technical structures of our everyday life. Accordingly, in upcoming years large mass streams of spent batteries are to be expected. Their handling and processing are as of now not yet clear. The colloquium will address the challenges of integrating Li-Ion batteries into a circular economy and give an insight into several new developments and technological concepts in fields of battery logistics, mechanical and pyrometallurgical processing.
Especially the expected growth rates in the field of electromobility will lead to a growing number of spent batteries in the near future. One battery unit of a full electric vehicle (PEV) weights typically more than 200 kg. The state of the art battery technology bases on Li-ion technology, using different active materials like iron-phosphate and nickel-, manganese-, and / or cobalt-oxides. Further components are metallic foils, organic electrolytes, special lithium-salts and electronic and structural components. Thus, spent batteries are an interesting subject to establish concepts of circular economy. Due to the complexity of the battery structure and the size of a typical battery cell, as well as its chemical and potential energy content, several challenges arise during the handling and the processing of the batteries.
