💡 Novelty & Significance:
The novelty lies in using an iodine-based solid-solid redox mediator pre-embedded in an amorphous sulfur/iodine nano-eutectic cathode. Iodine forms a percolating I2/I− nano-network that accelerates solid-solid sulfur redox and electron transfer. This enables fast charging (851.9 mAh g−1 at 10 C) and exceptional durability (9,000 cycles over 9 months), offering a design strategy for sluggish solid-state conversion electrodes.
