Title: Nickel based electrodes for high-performance thermogalvanic cells for waste heat harvesting

Abstract:

An important direction in the development of energy saving policy is the harvesting and conversion of low-grade waste heat into electricity. One of the simplest and cheapest ways to solve this problem is the development of thermogalvanic cells (TGC) [1]. In recent years, research efforts have resulted in significantly improved power and conversion efficiencies for TGC. However, the problems of stability and scalability for manufacturing are investigated very poorly. Nowadays nickel oxide is widely used electrode material for energy storage application due to its thermal stability, high chemical stability, low price, naturally abundant and environment friendliness [1].

Nickel oxide based electrodes for TGC cells were first investigated in [2] and their high efficiency in was shown. It was found that nickel based electrode ensures double power output in comparison with previously studied copper one and significantly higher output voltage is compared with the system based on ferri/ferrocyanide ([Fe(CN)₆]^3-/[Fe(CN)₆]^4-). That is supposed to the effect obtained with Ni electrodes characterized with well-developed surface area allows producing the commercial thermo-electrochemical cells for waste heat harvesting. Currently, systematic studies in the field of TGC based on nickel electrodes have not been published.
