Impact of calendering on carbon-sulfur composite electrode

Lithium-sulfur (Li-S) batteries have a higher energy density compared to lithium-ion batteries. The main components of Li-S batteries, sulfur, is inexpensive and sustainable, making it promising to be the successor of Li-ion batteries. One of the main obstacles to the commercialization of Li-S batteries is the low practical energy density. Consequently, most research focuses on exploring new materials to enhances energy density. The state-of-the-art processes for the fabrication of Li-ion electrode uses slurry casting methods. In order to commercialize the Li-S batteries, the energy density should be increase even with electrode fabricated through slurry casting. Typically, the slurry casting method consists of one complete set of processes, starting from pre-treatment of materials, mixing, casting, drying, and calendering. Understanding of the manufacturing processes and its correlation to the microstructure of electrodes will be beneficial for future implementation.
