Tritium release from neutron-irradiated Li2O: Transport in porous sintered pellets

Density Functional Theory Study for the Stability and Ionic Conductivity of Li2O Surfaces

“…Lithium diffusion in Li 2 O is a subject of great technological interest due to the superionic behavior of this material. , It is used in high-capacity energy storage devices for next-generation electric vehicles; in lightweight high-power-density lithium-ion batteries for heart pacemakers, mobile phones, and laptop computers; , and as blanket breeding material for deuterium−tritium fusion reactors. , …”

“…1,2 It is used in high-capacity energy storage devices for next-generation electric vehicles; in lightweight high-power-density lithium-ion batteries for heart pacemakers, mobile phones, and laptop computers; 3,4 and as blanket breeding material for deuteriumtritium fusion reactors. 5,6 Both theoretical and experimental investigations have been performed on defect properties [7][8][9][10][11][12][13][14] and the ion conduction mechanism 9,10,[14][15][16][17][18][19][20][21][22] in Li 2 O. It is well-known that lattice defects have a large effect on ion conductivity of ceramics.…”

Sistema para frenado de neutrones y reproducción de tritio en plantas de fusión nuclear por confinamiento inercial

“…La liberación de tritio debe ser lo suficientemente rápida para mantener el suministro de tritio de la planta. Por lo general, el transporte de tritio está limitado por la difusión a lo largo de los granos cerámicos, por lo tanto, la única forma de mejorar la liberación de tritio es aumentando la fracción de porosidad abierta y reduciendo el tamaño de grano, si es posible a la nano-escala, siempre que los granos resultantes sean estables a las temperaturas de operación [98,111,112].…”
