The need for an effective design of composite electrodes in all-solid-state Na-S batteries is warranted because of their slow charge–discharge reactions. By employing a composite of activated carbon MSP20, sulfur, and Na₃SbS₄ as the positive electrode material, we developed an effective all-solid-state Na-S battery that demonstrated the advantages of exhibiting a high capacity and good cyclability. Further, we discovered that filling the carbon micropores with sulfur and combining with highly conductive Na₃SbS₄, results in a reversible two-electron reaction between S and Na₂S. This all-solid-state Na-S battery, operating at room temperature, demonstrates a high capacity of 1560 mAh per gram of sulfur (ca. 330 mAh per gram of positive electrode) and a capacity retention of 93% after 50 cycles. Decreasing the size of the S-MSP20 particles coated with Na₃SbS₄ in a liquid phase process was observed to reduce the volume change of the particles during charge and discharge cycles, which resulted in an excellent electrochemical performance.

由于全固态Na-S电池的充放电反应缓慢，因此需要有效设计复合电极。通过使用活性炭MSP20，硫和Na ₃ SbS ₄的复合材料作为正极材料，我们开发了一种有效的全固态Na-S电池，该电池具有高容量和良好循环性的优点。此外，我们发现，用硫填充碳微孔并与高导电性的Na ₃ SbS _4结合，会导致S和Na ₂ S之间发生可逆的两电子反应。这种全固态Na-S电池可在室温下运行温度，表明每克硫1560 mAh的高容量（CA。每克正极330毫安时），经过50次循环后容量保持率为93％。观察到在液相工艺中减小涂覆有Na ₃ SbS ₄的S-MSP20颗粒的尺寸，以减小在充电和放电循环期间颗粒的体积变化，这导致优异的电化学性能。
