dc.description.abstract A theoretical investigation at density-functional level of Li ion conduction at the interfaces in Li2O:B2O3 nanocomposites is presented. The structural disorder at the Li2O(111):B2O3(001) interface leads to reduced defect formation energies for Li vacancies and Frenkel defects compared to Li2O surfaces. The average activation energy for Li+ diffusion in the interface region is in the range of the values for Li2O. It is therefore concluded that the enhanced Li conductivity of Li2O:B2O3 nanocomposites is mainly due to the increased defect concentration. © 2007 The American Physical Society. eng
