Application

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]
