Sigma-Aldrich SULFUR ELECTRODE SHEET ALUMINUM SUBST&

Our sublimed sulfur electrode sheet is a ready-to-use cathode for lithium-sulfur (Li-S) battery research. The sulfur film is cast single-sided on a 16-µM thick carbon-coated aluminum foil current collector that is 5 in. x 10 in. (127 mm x 254 mm) in size. The composition is 70% sublimed sulfur, 10% Poly(vinylidene fluoride) [PVDF] and 20% carbon black.

Our sublimed sulfur electrode sheet is primarily used as a cathode in lithium-sulfur batteries due to its high theoretical capacity. This sulfur cathode can convert sulfur to lithium sulfide by a conversion reaction, resulting in a practical capacity of 800 mAh/g that is 5× than those of the transition-metal oxide cathodes. It offers consistent, reliable performance and is suitable for experimental studies in lithium-sulfur (Li-S) battery chemistry. [1][2]
