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

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.
