is synthesized as a new sodium superionic conductor. The discovery of Na vacancies experimentally verifies previous theoretical predictions. Na vacancies, distorted cubic sulphur sublattices and large Na atomic displacement parameters lead to the ionic conductivity as high as 3 mS cm, a value significantly higher than those of state-of-the-art sodium sulfide electrolytes.
被合成成为一种新型的钠超离子导体。钠空位的发现通过实验验证了先前的理论预测。钠空位、扭曲的立方硫亚晶格和较大的钠原子位移参数导致离子电导率高达3 mS/cm,该值显著高于现有最先进的硫化钠电解质的电导率。
