Abstract
- Sodium metal chloride batteries, also called as ZEBRA batteries, possess many merits such as low cost, high energy density and high safety, but their high operation temperature (270–350 °C) may cause several issues and limit their applications. Therefore, decreasing the operation temperature is of great importance in order to broaden their usage. Using a room temperature ionic liquid (RTIL) catholyte composed of sodium chloride buffered 1-ethyl-3-methylimidazolium chloride–aluminum chloride and a dense β″-aluminates solid electrolyte film with 500 micron thickness, we report an intermediate temperature sodium copper chloride battery which can be operated at only 150 °C, therefore alleviating the corrosion issues, improving the material compatibilities and reducing the operating complexities associated with the conventional ZEBRA batteries. The RTIL presents a high ionic conductivity (0.247 S cm −1 ) at 150 °C and a wide electrochemical window (−2.6 to 2.18 vs. Al 3+ /Al). With the discharge plateau at 2.64 V toward sodium and the specific capacity of 285 mAh g −1 , this intermediate temperature battery exhibits an energy density (750 mWh g −1 ) comparable to the conventional ZEBRA batteries (728–785 mWh g −1 ) and superior to commercialized Li-ion batteries (550–680 mWh g −1 ), making it very attractive for renewable energy integration and other grid related applications.
