The superconducting transition temperature $T_c$ of LiFeAs decreases rapidly at a rate of 7 K per 1\\% V. The Hall coefficient of LiFeAs switches from negative to positive with 4.2\\% V doping, showing that V doping introduces hole carriers. This observation is further confirmed by the evaluation of the Fermi surface volume measured by angle-resolved photoemission spectroscopy (ARPES), from which a 0.3 hole doping per V atom introduced is deduced. Interestingly, the introduction of holes does not follow a rigid band shift.
