 This research has developed a new type of solid polymer electrolyte which can be used in sodium batteries. This electrolyte has been designed to have sub-nanometer-sized NA plus transport zones, allowing for faster reaction dynamics and improved stability. It also has a high ionic conductivity of 1.30 x 10 to the power of negative 4 SCM 1 and a low polarization voltage of 5.32 V versus NA plus NA at 25 degrees Celsius. These characteristics make it suitable for use in sodium batteries. This article was offered by Yin Chen Yang, Chen Liu, Ting WAN, and others.
