Figure of Merit Optimization to Improve Energy Efficiency in P-type CoSb3/Graphene Composite

Thermoelectric materials have emerged as a highly promising technology for generating electricity from heat, and recent research has demonstrated a significant enhancement of the electrical and thermal properties by incorporating graphene into a P-type CoSb
₃
matrix. The CoSb
₃
/graphene nanocomposite exhibits an excellent figure of merit (zT) due to its improved electrical and thermal performance. The dispersion of graphene plays a pivotal role in reducing thermal conductivity. The experiment employed pure CoSb
₃
, expertly crafted using the cutting-edge Spark Plasma Sintering approach. Remarkably, the addition of a mere 0.35 weight percentage of graphene led to a substantial 50% improvement in zT at mid-temperature, with a notable improvement of over 90% at low temperature comparing the untainted CoSb
₃
. The CoSb
₃
/Graphene nanocomposite has great potential for various applications, and we are thrilled to explore the possibilities further and continue to advance this exciting research.
