The effect of radiation type on defect production in Li2O

Transport and Charge Carrier Chemistry in Lithium Oxide

“…37 The impact of radiation at high temperatures has also been discussed. [38][39][40][41][42] Overall the previous studies are conclusive about the presence of Frenkel cation disorder, but significant quantitative disagreement remains regarding the derived enthalpies of Frenkel disorder, vacancy migration, and interstitial migration, which range from 1.1 to 2.5 eV, 0.3 to 1.0 eV, and 0.6 to 1.2 eV, respectively. The presence or absence of association at typical battery operation temperatures is also not well-understood, and for applications near room temperature, association is relevant because it lowers the concentration (and thus conductivity) of mobile ions.…”
