Lithium Nitride Li3N guides Li electrodeposition along its surface, creates a weakly solvating environment by decreasing Li+-solvent coordination. It also induces organic-poor solid-electrolyte interphases (SEI) on the Li metal anode and facilitates Li+ transport in the electrolyte. As a fast ion conductor, Li3N has been shown to enhance wettability between Li metal and solid state electrolytes (SSEs), effectively preventing the growth of Li dendrites. Additionally, as an interlayer material between lithium metal and SSEs, Li3N offers several advantages: (1) a high ionic conductivity of close to 1 mS·cm-1 at room temperature, guaranteeing fast transport of lithium ions; (2) improved physical contact between lithium metal and SSEs due to enhanced wettability; and (3) reduced loss of SSEs by isolating direct contact between lithium metal and the electrolyte. Overall, it is an effective way to form a stable ion-conducting layer by adding a Li3N between Li metal and the SSEs.

What is the ionic conductivity of Lithium Nitride Li3N powder at room temperature?
Lithium Nitride (Li3N) exhibits an ionic conductivity close to 1 mS·cm⁻¹ at room temperature. This high conductivity guarantees fast transport of lithium ions, making it effective as a solid-state electrolyte interlayer to reduce dendrite growth and improve battery performance.
How does Li3N improve the interface between lithium metal and solid-state electrolytes in all-solid-state batteries?
Li3N enhances wettability between lithium metal and solid-state electrolytes (SSEs), improving physical contact and reducing interfacial resistance. It also isolates direct contact between lithium metal and the electrolyte, minimizing SSE loss and forming a stable ion-conducting layer that suppresses dendrite formation.
What is the physical form and mesh size of the Li3N powder?
The product is a reddish-brown powder with a mesh size of -50 mesh. This physical form is suitable for direct use as an interlayer material in solid-state battery research and requires hazmat-classified special packaging and shipping.
