Resumo

With rising scientific evidence that human activity plays a major role in global warming, the demand for replacement of fossil-fuel-based energy sources in favor of renewable sources has greatly increased. Inseparably coupled to this, due to the intermittent nature of most renewable energy sources, is the development of efficient energy storage technologies. With reference to electric power storage, one attractive option is the redox flow battery (RFB), mainly due to the decoupling of the amount of energy stored and the rated power. The miniaturization of redox flow cells (RFCs) enables novel energy conversion concepts combining power delivery and heat regulation. In this lecture we discus recent developments [1, 2] demonstrating for the first time the realization of integration of high-power-density RFCs into electronic devices, providing electric power through conversion of chemical energy to electricity, and heat management (cooling) simultaneously. To this end, optimization of the enabling microfluidic networks in miniaturized flow cells is key. Employing 3D-printing for the inexpensive and effective fabrication of these networks, it was shown recently that RFCs with maximum power densities of up to 1.4 W cm-2 at room temperature and net power densities of up to 0.99 W cm-2 after accounting for pumping power losses (highest reported to date to our knowledge) are possible [1, 2].
