摘　　要：以钠硫单体实验电池(型号为NS-2)为研究对象,通过60个充放电循环,研究了循环次数和放电深度对输出电压的影响。结果表明,NS-2型钠硫电池在20Ah以内有一个较好的放点平台。根据输出电压对循环次数曲线的拟合公式推算,NS-2型钠硫电池可达到1250次循环。The properties of sodium-sulfur battery（model NS-2） were investigated.Through in 60 charge-discharge cycles,the influence of the depth of discharge and cycle numbers on discharge voltage were studied.The results indicated that the NS-2 sodium-sulfur battery had a perfect discharge platform with about 20Ah depth of discharge.Following the fitting formula from the curve of discharge voltage V versus cycle number N,the cycle number of NS-2 sodium-sulfur battery will be 1250.
