The ÖkoMatBatt project is concerned with the development of ecologically and economically sustainable materials for the lithium-ion battery. The polymeric binders currently used in electrodes of lithium-ion batteries contain halogens, involve the use of reproduction-toxic solvents in electrode production and pose recycling and thermal safety problems (formation of hydrogen fluoride due to fluorine-containing binders). Alternative binders and solvents should be used for the production and application of the battery suspensions, with electrochemical performance compared to commercial electrodes of high energy electrodes.
Project objectives
The aim of the project is to functionalize the binder side and adapt it to the active materials on the cathode side in terms of wettability, adhesion and flexibility. At the same time, toxic/carcinogenic solvents are substituted and the ecological incentive of bio-based materials increases the acceptance of lithium-ion batteries. The impact of the polymers produced and their functionalization is continuously documented and evaluated by means of life cycle analyses. In addition to the raw material source, the processing of the individual components such as active materials, binders and solvents into sustainable and competitive battery electrodes and cells is also evaluated.
