About this Research Topic
Energy is the core issue for the booming and sustainable development of our societies. The depleting of fossil fuel and the severer climate conditions make an urgent requirement for clean energy alternatives. Heat, abundantly available from nature, industries and human society, shows the great potential to match the growing energy thirsty. The exploration on Thermoelectrichemicals and thermoelectrics, based on electrochemical system and semiconducting materials, respectively, are aimed indirectly convert heat into electricity under high efficiency, concise and flexible design, and simple operation mode. The traditional heat-to-electricity technologies-Steam engine-invented in the industrial revolution has led human to the world with power and now we are expecting the new revolution with the emerging technologies from thermoelectrical and thermoelectric system for leading us to a smart and sustainable future.
Thermoelectrochemical and thermoelectric system are the emerging heat-to-electricity technologies operated under the direct conversion without moving parts. On one hand, these technologies shed light on the pressure release of energy shortage and climate changes; on the other hand, their simple and flexible operation mode make them feasible for the distributed heat sources and offers the best opportunities to power the smart future city. The development of these technologies relies on interdisciplinary views ranging from physics and chemistry, mechanics and nanotechnologies. The related researches cover the exploration of the fundamental principles, the fabrication of new materials and devices, and the various practical applications. This research topic aims to provide a platform to publish outstanding research, collecting on-going discussions, sharing the latest advances and building the community on the thermoelectrochemical and thermoelectric materials and devices for advanced energy application.
