Direct Thermal Charging Cell - Gold Medal

Summary: This Direct thermal charging cell (DTCC System) is a new invention for efficient conversion of low-grade heat to electricity. It is the first demonstration of heat-to-electricity conversion under isothermal heating and chemical regeneration, which revolutionizes the design of thermoelectrochemical systems.

Technology Benefits: This DTCC cell is a simple system with benefits include the ability to form stacks of cells (stackable), continuous charging / discharging operation, bendable and low-cost.

Detailed Technology Description: This DTCC System used asymmetric electrodes of grapheme oxide (GO)/Pt nanoparticles cathode and polyaniline anode in aqueous Fe2+/Fe3+ redox electrolyte for efficient conversion of low-grade heat to electricity. Continuous energy conversion is achieved under isothermal heating throughout the charge and discharge process. The system can be self-regenerated when cooled down, thus allowing device cyclability. This system is the first demonstration of heat-to-electricity conversion under isothermal heating and chemical regeneration, which revolutionizes the design of thermoelectrochemical systems. It is fundamentally different from the state-of-the-art technologies with power generation coupled to temperature differential.
