ZINTL COMPOUNDS WITH HIGH THERMOELECTIC PERFORMANCE AND METHODS OF MANUFACTURE THEREOF

摘要

Systems and methods discussed herein relate to Zintl-type thermoelectric materials, including a p-type thermoelectric material according to the formula AM_yX_y, and includes at least one of calcium (Ca), europium (Eu), ytterbium (Yb), and strontium (Sr), and has a ZT of the above about 0.60 above 675K. The n-type thermoelectric component includes magnesium (Mg), tellurium (Te), antimony (Sb), and bismuth (Bi) according to the formula Mg_3.2Sb_1.5Bi_0.5-xTe_x that has an average ZT above 0.8 from 400K to 800K.. The p-type and n-type materials discussed herein may be used alone, in combination with other materials, or in combination with each other in various configurations.
