A team of researchers in the US (SUNY Buffalo, University of Maryland, US Army Aberdeen Proving Ground) tested if two dissimilar materials – molecular energetic materials and ferroelectrics – can be combined to obtain a chemically driven electrical energy source with high-power density. They designed energetic molecular ferroelectrics consisting of imidazolium cations (energetic ion) and perchlorate anions (oxidizer) and described its thermal wave energy conversion with a specific power of 1.8 kW kg−1. They showed that chemically driven energy generator is a result of the coupling between energetic thermal and shock waves and a pyroelectric effect in molecular ferroelectrics and the polarization of molecular energetic ferroelectrics can control the energy density and energy release rate of the available chemical energy. The technique is a promising strategy for emerging energy applications demanding high power density. Such a power source could potentially be employed for on-demand energy sources, propulsion, or thermal batteries…read more. Open Access TECHNICAL ARTICLEÂ
