Operando characterisation techniques for graphene-based lithium-sulfur batteries
Lithium-sulfur (Li-S) batteries have the potential to enable high-gravimetric capacity, low-cost energy storage, but their widespread implementation is presently limited by their rapid capacity degradation due to irreversible loss of electrical connectivity with their active material. Electrically …
