GRAPHENE THERMOCELL FOR ENERGY HARVESTING DEVICE AND A PROCESS FOR MANUFACTURE THEREOF

摘要

The present disclosure provides a graphene based thermocell for energy harvesting device and a process for manufacture thereof. The thermocell comprises a first electrode, a second electrode, and a redox electrolyte, characterized in that at least a portion of at least one of the first electrode and the second electrode is coated with graphene. The temperature difference between the first electrode and the second electrode is in the range of 40° C. to 80° C. The present disclosure also provides an energy harvesting device comprising plurality of graphene based thermocells that are electrically connected in series. The energy harvesting device is cost-effective and has a maximum energy conversion efficiency of 3.59% and maximum relative carnot efficiency of 20.2%.
