Successful encapsulation by the polymer was confirmed by microscopic analyses. The encapsulated sulfur electrodes exhibit stable cycling performance and high sulfur utilization; in particular, the cell with 1 wt% dual conducting polymer-coated sulfur particles exhibit the best cycle performance with a discharge capacity of 1002 mAh g(-1) after 100 cycles at 0.2 C-rate. As opposed to various sulfur-carbon composites reported previously, our 1 wt% dual conducting polymer-coated sulfur composite achieves a very high loading level of 99%. This simple strategy of encapsulating sulfur particles with functional polymers could be a potential pathway toward the commercialization of Li-S batteries. (c) 2018 Elsevier B.V.
