Pre-embedded iodine redox mediation in amorphous sulfur/iodine nano-eutectic all-solid-state Li–S batteries enables fast charging and durable cycling, delivering 851.9 mA h g−1 S/I at 10 C.
- Why it matters: Solid-solid sulfur redox reactions are slow in all-solid-state Li–S cells, limiting rate capability and cycling stability.
- What they did: The authors used a pre-embedded solid-solid redox mediator with carbon mesopore encapsulation to homogenize iodine with sulfur, forming an in situ I2/I− nano-network in the positive electrode.
- The result: The cells achieved 474.7 mA h g−1 S/I at 24 C and maintained 9,000 cycles over 9 months at 2 C and 2,800 cycles over 17 months at 0.5 C.
