The lattice parameters (a, b, and c), the interplanar crystal spacing (d ₀₂₂ and d ₀₀₂), the unit‐cell volume (V) and intercalation energy (ΔE _Li) of LMNO with and without Li‐ion intercalation

System	a [nm]	b [nm]	c [nm]	d 022 [nm] a)	d 002 [nm]	V [nm3]	ΔE Li [eV]
La8Mn4Ni4O24	0.777	0.777	0.777	0.275	0.387	0.469	0
La8Mn4Ni4O24 + Li	0.790	0.790	0.788	0.280	0.395	0.491	−1.47
La8Mn4Ni4O24 + 16Li	0.842	0.842	0.842	0.298	0.421	0.574	−0.63

^a) Note that in double‐perovskite crystalline, the spacing of (022) crystal plane is equal to that of (202), ($02\overline{2}$) and ($\overline{2}20$).
