可再生能源的广泛渗透和对电网可靠性/安全性的日益增长的需求需要能源存储技术的广泛进步。一种最有前途的技术是基于钠离子导电β " -Al2O3固体电解质（BASE）并在高温（300-350℃）下工作的钠- β电池（NBBs）。目前的nbb采用1-3毫米厚的管状电解质，存在资金成本高、性能/安全问题以及相对较高的工作温度等问题，限制了该技术的市场渗透率。在这项工作中，我们报告了采用平面设计的新一代NBB，采用更薄的BASE，减少了比电阻面积，可以在更低的温度下工作。较低的工作温度允许使用更具成本效益的电池材料，并减少影响循环寿命和总成本的不利温度效应。我们在此介绍了平面NBB钮扣电池的最新进展，包括初始电池性能、阴极设计和化学。
Widespread penetration of renewable energy and increasing demands on reliability/security of the electrical grid require extensive advances in energy storage technologies. One most promising technology is the sodium-beta batteries (NBBs) based on a sodium-ion conducting β''-Al2O3 solid electrolyte (BASE) and operated at elevated temperatures (300-350oC). Current NBBs, constructed on a 1-3 mm thick tubular electrolyte, have high capital cost, performance/safety issues and relatively high operating temperature that limit market penetration of the technology. In this work we report a new generation NBB that utilizes a planar design, incorporating a thinner BASE that reduces the area of specific resistance and may be operated at reduced temperatures. The lower operating temperatures allows for use of more cost-effective cell materials and decreases adverse temperature effects that impact cycle life and overall cost. We here present recent progress generated from planar NBB button cells, including initial cell performance, cathode design and chemistry.
