Repository for paper Fluorine-free Lithium Ion Batteries: A Working Alternative. Abstract of paper:

Current commercial battery designs contain fluorinated materials as binders and electrolyte salts to ensure high electrochemical and thermal stability. Upcoming regulations in Europe and the US restrict the manufacturing of such materials, as their persistence in drinking water and soil can cause long term ecological harm. In this perspective, we showcase a completely fluorine-free battery design which has similar performance compared to commercial standards, while using aqueous processed LiNi0.8Mn0.1Co0.1O2 (NMC811) and graphite as cathode and anode active materials respectively. The cell shows 98% retained capacity after 600 cycles at room temperature, indicating good stability of active material with non-fluorinated binders. The charge rate performance (69% retained capacity at 1C, 1.5 mAh/cm2) could be improved by combining two fluorine-free salts (67% retained capacity at 1C with 2.5 times the loading, 3.3 mAh/cm2). This work illustrates that fluorine-free cell designs show good battery performance over awide potential window.
