利用高压合成技术，成功地将最轻的离子半径小的金属元素锂填充到CoSb 3的空隙中。合成的Li0.4Co4Sb12在所有元素填充的CoSb3材料中显示出最大的热电功率因数6000 μW m−1 K−2。这种显著增强的热电功率因数归因于Li0.4Co4Sb12的大载流子迁移率，61 cm2 V−1 s−1，具有Li填充的CoSb3样品的良好电子晶体性质。
Lithium, the lightest metal element with a small ionic radius, is successfully filled into the voids of CoSb3 by utilizing the high pressure synthesis technique. The synthesized Li0.4Co4Sb12 shows the largest thermoelectric power factor of 6000 μW m−1 K−2 among all elemental filled CoSb3 materials. This significantly enhanced thermoelectric power factor is attributed to the large carrier mobility of Li0.4Co4Sb12, 61 cm2 V−1 s−1, featuring a good electron crystal property for the Li-filled CoSb3 samples.
