Solid‐state sodium batteries (SSSBs) are considered as promising candidates for next‐generation energy storage applications due to the probability to achieve safer and higher energy density characteristics. However, though SSSBs can avoid using combustible organic liquid electrolytes, the development of such novel batteries is hindered by some critical challenges. Particularly, comprehensive understandings of interfacial stability between solid‐state electrolyte and two electrodes is still absent and thus there is a long way to go for practical applications of SSSBs. In this regard, this review focuses on the grand challenges, fundamental mechanisms, and viable design strategies associated with the interfaces in SSSBs. First, the differences between liquid‐ and solid‐state batteries are compared, and the challenges remaining to be conquered are pointed out. Second, a variety of interfaces, such as interphase formation, interface between electrode and electrolyte, as well as interface of interparticle, are discussed in detail to guide the engineering of the interfaces. Following the obtained insights, systematic perspectives are listed at last to form a basis for further development of advanced SSSBs.
