(Photo: Hiromichi Ohta) CREDIT Hiromichi Ohta Abstract: Scientists at Hokkaido University have developed a layered cobalt oxide with a record-setting thermoelectric figure of merit, which can be used to enhance thermoelectric power generation. Record-setting thermoelectric figure of merit achieved for metal oxides Hokkaido, Japan | Posted on December 29th, 2020 Waste heat is a highly promising source of renewable energy; however, the efficiency of using heat to generate energy has historically been much lower than hydroelectric, wind or solar power. While there are a number of materials that can be used for the generation of energy from waste heat, they all suffer from various issues ranging from low stability to low efficiency. Nevertheless, the fact that a large number of in
