The effect of sulfur loading on the electrochemical performance of a sulfur–polymer composite cathode coated on aluminium foil

Abstract

A scaling-up investigation of a sulfur–polymer cathode for rechargeable lithium–sulfur batteries is reported. The proposed procedure uses a low cost aluminium current collector and is suitable for mass production of a composite cathode, with sulfur loading levels of up to 5.9 mg cm⁻², and good electrochemical performance.
