| Abstract Scope |
Today’s electrical power generation is produced primarily via fossil fuel-based energy conversion technologies, which contribute significantly to carbon emissions. Meanwhile, with the implantation of various recuperation technologies, approximately 20% to 50% of industrial energy input for power generation is still lost as waste heat. To increase the energy sustainability, thermoelectric technology could be integrated into multiple power generation systems to convert waste heat into green electricity directly. The misfit layered eco-friendly p-type Bi2Ca2Co2-xOδ is one novel and promising thermoelectric oxide that could be employed in thermoelectric power generators for applications in the air directly. The present study explores the direct pathways of “powders” to “power” by additive manufacturing and printing the oxide precursor powders into bulk-scale thermoelectric ceramics directly. The systematic approach of optimization of the precursor powder synthesis conditions and printing protocols and subsequent processing to ensure the formation of the crystal texture and high thermoelectric performance is presented. |
