Improved performance of sulfur cathode by an easy and scale-up coating strategy
A new fabricating process for high-performance sulfur cathode is proposed. The fabricating process relies on two-step coating technique: firstly, high sulfur content slurry is coated on the current collector. After drying, the electrode is coated with another slurry composed of Super P and binder. The sulfur electrode with relatively high sulfur content/loading of 60 wt%/2 mg cm(-2) discharges capacity of similar to 695 mAh g(-1) at 0.5 C after 100 cycling. This method is easy for industrialization and well controlled over the areal sulfur loading and mass, therefore it is efficient for fabricating high-performance Li-S batteries with high-energy density.
