Patent ID: 11805699

Abstract:
Disclosed herein are doped thermoelectric ceramic oxide compositions comprising a calcium cobaltite ceramic. The doped thermoelectric ceramic oxide compositions can have a formula Ca3-xM2xCo4O9M1y, where M1 represents a first metal dopant, M2 represents a second metal dopant, x is a number having a value of from about 0.00 to about 3.00, and y is a number having a value of from about 0.01 to about 0.50. The doped thermoelectric ceramic oxide compositions have an increased energy conversion efficiency as compared to an undoped or conventional thermoelectric ceramic oxide materials. Also disclosed are methods for making the doped thermoelectric ceramic oxide compositions. Products and devices are disclosed comprising the thermoelectric ceramic oxide compositions, e.g., solid-state conversion devices that can utilize heat to generate electricity. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
