Solid-state sodium batteries are heralded as the next frontier in energy storage, promising high energy density and unparalleled safety. The linchpin of this technology lies in solid-state electrolytes, which underpin the electrochemical performance of these batteries. Among them, NASICON-type Na₃Zr₂Si₂PO₁₂ (NZSP) oxide ceramic solid-state electrolytes have garnered significant attention due to their impressive ionic conductivity, air stability, and robust shear modulus. However, the pervasive dendrite issue poses a formidable challenge to the widespread adoption of NZSP-based all-solid-state batteries, with the growth mechanism of these dendrites in NZSP electrolytes remaining a mystery. Leveraging in-situ observation and multi-physics field simulation, the research teams led by Professor Han Xiaogang and Professor Song Zhongxiao at Xi'an Jiaotong University have delved deeply into dendrite growth and crack propagation in NZSP solid-state electrolytes. Their findings have unveiled the intricate interplay between these two phenomena and have paved the way for innovative strategies to curb dendrite formation.
