Application of lithium nitride
Lithium nitride is a fast ionic conductor and its electrical conductivity is higher than other inorganic lithium salts. Many studies have been conducted on the application of lithium nitride as a solid electrode and cathode material for batteries.
In addition to being used as a solid electrolyte, lithium nitride is an effective catalyst for the conversion of hexagonal boron nitride to cubic boron nitride.
To improve the performance of OLED devices, lithium nitride (Li3N) was used as an N-type dopant in the electron transport material Tris (8-Hydroxy Quinoline) Aluminium (AlQ3) layer. It has been reported that Li3N can improve the performance of the device as a buffer layer between the electron injection layer and the cathode. During the evaporation process, Li3N is decomposed into Li and N2, only Li can be deposited in the device, and N2 has no adverse effect on device performance. The experimental results show that the Li3N-doped AlQ3 layer, as the electron injection layer, can effectively improve the efficiency of OLED and reduce the operating voltage of the device.
The fast ion conduction lithium nitride is grown as a "graphene" model
Due to its special room temperature ionic conductivity (10-3 S cm-1), lithium nitride (Li3N) was initially proposed as an electrolyte for all-solid-state lithium-ion batteries. In fact, crystalline lithium ions have been the highest conducting crystalline lithium-ion conductor under environmental conditions for several decades, despite attempts to stabilize it and despite the fact that its low decomposition potential has hindered its application. However, doping the late transition metal triggers electrical conductivity, which can be used in the negative electrode with twice the charging capacity of graphite. In addition, Li3N has been proposed for countless other applications, for example, as a means of converting CO2 into useful products; As an electron injection layer in organic light-emitting diodes and as an unusual reducing agent in the preparation of organic chemistry and organometallic chemistry. Back in 2002, Li3N was found to be a potential candidate for solid hydrogen storage because it can hold up to 10.4 wt.% H2. However, the slow kinetics of hydrogen adsorption and high (dehydrogenation) temperatures are major obstacles to overcome before lithium hydrogen systems can be commercially developed.
It has been found that both single and two-dimensional nanostructures of lithium nitride can grow without an equivalent van der Waals gap. Compared with bulk compounds, lithium-ion diffusion is enhanced, resulting in materials with special ion mobility.
Li3N demonstrates the concept of assembling ionic inorganic nanostructures from a monolayer without the need for van der Waals gaps. Computational studies reveal a Li-N layer mediated electronic structure transitioning from a large, narrow bandgap semiconductor to metal at the nanoscale.
