This work provides a commercially adoptable route to prepare Li3N containing electrode, using low toxic and high boiling point N,N-dimethylformamide (DMF) to homogenate the electrode slurry. The stabilization mechanism of Li3N in DMF solvent is found closely related with its dehydrogenation energy, which is much larger than other commonly used solvents such as N-methy-2-pyrrolidone (NMP), dimethylacetamide (DMAC), dimethyl sulfoxide (DMSO) and Acetonitrile (ACN). As a result, researchers successfully manufactured a soft package lithium ion hybrid capacitors, which exhibits excellent energy density and power density as high as 130.1 Wh/kg and 5056.9 W/kg based on all active materials.
