Abstract: 본발명은리튬황 배터리에서수명의개선을위한것이다. 황양극은완전충전상태에서고체유황이고, 방전상태에서는 LiS 이다. LiS는유황의 180%에해당하는부피이다. 리튬황배터리의양극은충전-방전을반복하면이에따른부피팽창과수축에의하여구조가붕괴된다. 본발명은 LiS 분말을도전재로복합화하여감싼양극구조를특징으로한다. 이러한구조는부피가팽창상태의활물질에맞는구조를유지하기때문에, 반복되는충전과방전사이클을거치면서도부피팽창에의한양극구조의붕괴를회피하여리튬황배터리의수명을개선하였다.
Abstract translation: 本发明是为了提高锂硫电池的寿命。 硫正电极是处于完全充电状态的固体硫,并且是处于完全放电状态的Li 2 S。 Li_2S的体积对应于硫的180%。 如果重复充放电,则锂 - 硫电池的正极结构随着体积膨胀和收缩而折叠。 本发明具有由具有导电材料的Li_2S粉末组合包围的正极结构。 本发明的结构保持适合于体积膨胀的活性材料的结构,从而即使经历重复的充放电循环也避免了由体积膨胀引起的正极结构的塌陷,从而提高了锂硫电池的寿命。
