“…A lot of efforts were directed to the development of more advanced batteries. For example, different approaches for LIB's development were used, such as nanostructured materials [1][2][3][4][5][6][7][8][9][10][11][12][13], the growth of the capacity and voltage of cathode materials [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30], hollow and porous and structures [13,[31][32][33][34][35][36][37][38][39][40][41][42][43][44], safety issues, including separator and liquid electrolyte studies [45][46][47][48]…”

Li3FeN2 material was synthesized by the two-step solid-state method from Li3N (adiabatic camera) and FeN2 (tube furnace) powders. Phase investigation of Li3N, FeN2, and Li3FeN2 was carried out. The discharge capacity of Li3FeN2 is 343 mAh g−1, which is about 44.7% of the theoretic capacity. The ternary nitride Li3FeN2 molar heat capacity is calculated using the formula Cp,m = 77.831 + 0.130 × T − 6289 × T−2, (T is absolute temperature, temperature range is 298–900 K, pressure is constant). The thermodynamic characteristics of Li3FeN2 have the following values: entropy S0298 = 116.2 J mol−1 K−1, molar enthalpy of dissolution ΔdHLFN = −206.537 ± 2.8 kJ mol−1, the standard enthalpy of formation ΔfH0 = −291.331 ± 5.7 kJ mol−1, entropy S0298 = 113.2 J mol−1 K−1 (Neumann–Kopp rule) and 116.2 J mol−1 K−1 (W. Herz rule), the standard Gibbs free energy of formation ΔfG0298 = −276.7 kJ mol−1.
