22. 2 with Li/Ti=0.143. The energy differences between two configurations are found to be negligible within the numerical precision. But, for Fe-doped case, the insulating state prefers the AFM configuration of Fe spins.
23. F are not changed much.

27. F's are determined by dispersive Ti 3d states.
28. c can be obtained through optimizing the carrier concentration by the voltage controlled Li-intercalation, as described below.
