New binders for Lithium-Sulfur-Batteries

Kurzfassung

PVDF, a common binder for sulfur-cathodes, requires toxic and/or low-volatile solvents. The drying conditions of such cathodes are either extreme, with loss of active material by sublimation or ambient, which enhance fabrication cost. Due to economically viable application processes, enhanced substrate adhesion, mechanical strength, chemical resistance, material and fabrication costs phenolic-, polyurethane-, epoxy- and silicon-based binders are studied, considering the binders electrochemical resistance first.
