Under the Li-rich condition (Figure ), E Fermi,eq is at 5.83 eV. V 0 O , Li +1 i , and V -1 Li are the dominant defects, but still show relatively high E D,q (averaged over all Wycko↵ sites) of 0.90 eV, 1.34 eV, and 1.47 eV, respectively. The total concentration of Li +1 i and V - 1 Li , which mediate Li-ion di↵usion, is only 3.35 ⇥ 10 1 cm 3 . These oppositely charged defects are present in almost equal concentrations and leads to charge self compensation. Therefore, the net free charge carrier concentration is negligible ⇡ 0 cm 3 (order of 10 45 cm 3 ).
