Effect of temperature and species-specific vacancy defects on the thermal conductivity of LiAlO2 and LiAl5O8. Degradation of thermal conductivity as a function of temperature for LiAlO2 in (a) and for LiAl5O8 in (b) compared with experimental data from41. (c) Reduction in thermal conductivity of γ-LiAlO2 as a function of Li vacancy concentration and (d) Al vacancy concentration, which has a more pronounced effect compared to Li vacancies. Thermal conductivity response of LiAl5O8 to (e) Li vacancies, showing relatively modest impact due to the more resilient structure that mitigates phonon scattering effects from isolated Li site disruption. (f) Impact of Al vacancies in LiAl5O8.
