Lithium, the lightest metal element with a small ionic radius, is successfully filled into the voids of CoSb{sub 3} by utilizing the high pressure synthesis technique. The synthesized Li{sub 0.4}Co{sub 4}Sb{sub 12} shows the largest thermoelectric power factor of 6000 {mu}W m{sup -1} K{sup -2} among all elemental filled CoSb{sub 3} materials. This significantly enhanced thermoelectric power factor is attributed to the large carrier mobility of Li{sub 0.4}Co{sub 4}Sb{sub 12}, 61 cm{sup 2} V{sup -1} s{sup -1}, featuring a good electron crystal property for the Li-filled CoSb{sub 3} samples.
