Direct conversion of the tremendous and ubiquitous low-grade thermal energy into electricity by thermogalvanic cells is a promising strategy for energy harvesting. The environment is one of the richest and renewable low-grade thermal source. However, critical challenges remain for all-day electricity generation from environmental thermal energy due to the low frequency and small amplitude of

The initial part of this work focused on an investigation of K3Fe(CN)6/K4Fe(CN)6 concentration (in aqueous media) as the electrolyte for thermocell applications with carbon based electrodes. Thermocell performance is maximised through the use of 0.4 M K3Fe(CN)6/K4Fe(CN)6 due to the low thermal conductivity and high ionic conductivity of said solution.
