MOSCOW, Aug. 28, 2020 /PRNewswire/ — Scientists from NUST MISIS have developed a new type of energy-efficient devices – thermocells that convert heat into energy. This will make possible creation of portable batteries that can be applied to virtually any surface, including clothing, to generate electricity directly from the surface of the body. The results are presented in the Renewable Energy journal.
Thermoelectricity – electricity obtained from heat due to temperature potential differences – is one of the most promising areas of “green energy”. This potential difference (the so-called temperature gradients) surrounds us everywhere – a building heated in the sun, a working transport, even the heat of the human body. The problem is that the modern thermoelectrochemical cells (thermocells) have a rather low output power.
Scientists from NUST MISIS have found solutions to this problem by developing a new type of thermocell consisting of metal oxide electrodes and
