可充电锂离子电池在过去的20年里一直统治着消费电子市场，并且在越来越多的电动汽车和固定储能应用中具有重要意义。然而，除了对电化学性能的担忧之外，锂的有限可用性正逐渐成为进一步持续使用和开发锂离子电池的重要问题。因此，注意力已经发生了重大转变，转向新型可充电电池，例如具有低成本的钠基系统。钠电池的另一个重要方面是它与全固态设计的潜在兼容性，其中固体电解质用于取代液体电解质，从而导致电池设计简单，寿命长，安全性好。全固态电池设计成功的关键是找到在室温下具有可接受的高离子电导率的固体电解质。在此，我们报道了一种具有NASICON结构的新型钠超离子导体Na3.1Zr1.95Mg0.05Si2PO12，其室温离子电导率为3.5 × 10−3 S cm−1。我们还报道了使用这种导体的室温固态Na-S电池的成功制造。
Rechargeable lithium ion batteries have ruled the consumer electronics market for the past 20 years and have great significance in the growing number of electric vehicles and stationary energy storage applications. However, in addition to concerns about electrochemical performance, the limited availability of lithium is gradually becoming an important issue for further continued use and development of lithium ion batteries. Therefore, a significant shift in attention has been taking place towards new types of rechargeable batteries such as sodium-based systems that have low cost. Another important aspect of sodium battery is its potential compatibility with the all-solid-state design where solid electrolyte is used to replace liquid one, leading to simple battery design, long life span, and excellent safety. The key to the success of all-solid-state battery design is the challenge of finding solid electrolytes possessing acceptable high ionic conductivities at room temperature. Herein, we report a novel sodium superionic conductor with NASICON structure, Na3.1Zr1.95Mg0.05Si2PO12 that shows high room-temperature ionic conductivity of 3.5 × 10−3 S cm−1. We also report successful fabrication of a room-temperature solid-state Na-S cell using this conductor.
