Abstract

The EU-funded collaborative MARS-EV Project (FP7, grant agreement 609201) has been targeting inter alia the"br" realization of aqueous electrode processing technologies for high-energy lithium-ion positive electrodes with a"br" particular focus on achieving the high recycling requirements established by the European Commission in its"br" Battery Directive 2006/66 EG, stipulating a minimum recycling rate of 50%. Indeed, the aqueous electrode"br" fabrication does not only allow for avoiding the use of environmentally hazardous, toxic, and expensive organic"br" solvents as well as the need for super-dry conditions up to the cell assembly, but moreover a facilitated recycling"br" process due to the water-soluble binding agents. Additionally, of great importance with regard to the latter is the"br" careful selection of the cathode chemistry – not least with respect to economic aspects."br" Herein, we summarize the results and progresses obtained within MARS-EV, highlighting their importance for"br" the realization of environmentally friendly lithium-ion batteries for a sustainably electrified transportation.
