  title = {Electrostatic Polysulfides Confinement to Inhibit Redox Shuttle Process in the Lithium Sulfur Batteries},
  abstract = {<p>Cationic polymer can capture polysulfide ions and inhibit polysulfide shuttle effect in lithium sulfur (Li-S) rechargeable batteries, enhancing the Li-S battery cycling performance. The cationic poly[bis(2-chloroethyl) ether-alt-1,3-bis[3-(dimethylamino) propyl]urea] quaternized (PQ) with a high density quaternary ammonium cations can trap the lithium polysulfide through the electrostatic attraction between positively charged quaternary ammonium (R<sub>4</sub>N<sup>+</sup>) and negatively charged polysulfide (S<sub>x</sub><sup>2-</sup>). PQ binder based sulfur electrodes deliver much higher capacity and provide better stability than traditional polyvinylidene fluoride (PVDF) binder based electrodes in Li-S cells. A high sulfur loading of 7.5 mg/<span>cm</span><sup>2</sup> is achieved, which delivers a high initial areal capacity of 9.0 mAh/<span>cm</span><sup>2</sup> and stable cycling capacity at around 7.0 mAh/cm<sup>2</sup> in the following cycles.</p>},
