Sulfur is an electrical insulator and cannot effectively conduct electrons. Carbon fiber has excellent conductivity. Mixing carbon fiber with sulfur can significantly improve the overall conductivity of the positive electrode, thereby increasing the energy output of the battery.

[0026] When the battery is discharged,
[0027] Negative electrode: Li→Li++e-
[0028] Positive electrode: The sulfur film is reduced and combines with lithium ions to form lithium sulfide.

[0031] Li2S:Sx2-+2Li++2e-→Li2S

[0033] Positive electrode: oxidation reaction of lithium sulfide
[0034] Li2S→S+2Li++2e-
[0035] Negative electrode: reduction of lithium ions and deposition of lithium metal
[0036] Li++e-→Li
