钠/硫(Na/S)电池由金属钠负极、液体电解液和硫复合正极组装而成。研究了它们在室温下的电化学性质。它们的充放电曲线表明，钠和硫在室温下可以发生可逆反应。硫磺复合正极材料首次循环比容量约为655mAhg−1，至第18次循环保持约500mAhg−1，充放电效率约为100%。
Sodium/sulfur (Na/S) batteries were assembled with a sodium metal anode, liquid electrolyte and a sulfur composite cathode. Their electrochemical characteristics have been investigated at room temperature. Their charge/discharge curves indicate that sodium can reversibly react with sulfur at room temperature. The specific capacity of the sulfur composite cathode material in the first cycle was initially about 655mAhg−1and stayed at about 500mAhg−1up to the 18th cycle with about 100% charge/discharge efficiency.
