In addition to high reactivity and mobile interface, all-solid-state lithium metal batteries (ASSLMBs) still faces severe inhomogeneity in mechanical and electrochemical properties. The inherent trade-off in ASSLMBs lies between ionic conductivity and electrochemical window, mechanical strength and interface contact adequacy.

Schematic of the structure of a typical Li-ion battery and a solid-state lithium metal battery. a) A typical LIB consists of a transition metal cathode, a graphitic anode, and an aprotic liquid electrolyte. b) In a SSLMB, a Li-metal anode is coupled to a transition metal cathode via a solid-state electrolyte.
