Abstract:
Due to their high theoretical energy densities, lithium sulfur (Li-S) batteries are currently some of the most extensively investigated electrochemical power sources. As a sustainable and environmentally friendly biopolymer, guar gum (GG) is chosen as a binder for use in Li-S batteries for the first time. The results show that GG is a promising binder for sulfur composite cathode materials, and exhibits excellent cycling performance and a favorable high rate capability.
