Rational Design of Layered SnS2 on Ultralight Graphene Fiber Fabrics as Binder-Free Anodes for Enhanced Practical Capacity of Sodium-Ion Batteries
2019
Layered SnS2 nanosheets/reduced graphene fiber (SnS2@rGF) hybrid fabrics were fabricated as binder-free electrodes.
Ultralight rGF fabrics could increase the active materials loading to a high level of 67.2 wt% in the whole electrode, which is much higher than that of traditional slurry coating electrodes by using Cu or Al foil as current collectors.
The practical capacity based on the weight of electrode could increase to as high as ~ 538 mAh g−1 exceeding to the slurry coating electrodes.
