Abstract:
For the first time, we report the employment of an ultrathin alucone film enabled by the molecular layer deposition technique to dramatically stabilize the sulfur cathodes for Li-S batteries. The alucone coated C/S cathode displayed over two-times higher discharge capacity than the pristine one after 100 cycles, demonstrating a greatly prolonged cycle life.
