초록
Na-ZnCl2 battery, which operates as the same mechanism of Na-NiCl2 battery using solid-electrolyte, is able to reduce its material cost by 40 % comparing to the Na-NiCl2 battery. It has been known that the Na-ZnCl2 battery produces Na2ZnCl4 as an intermediate phase during charge/discharge process. Therefore, the redox process is divided into four steps having the voltage range of 1.92~2.13 V. However, effects of the critical factors such as the composition of cathode materials, depth of charge and discharge, and additives have not been reported yet. We examined the effect of the Zn/NaCl ratios and revealed that its optimum ratio was in the range of 1.3~1.7.
