Use of Carbon Additives towards Rechargeable Zinc Slurry Air Flow Batteries
Original language description
The performance of redox flow batteries is notably influenced by the electrolyte, especially in slurry-based flow batteries, as it serves as both an ionic conductive electrolyte and a flowing electrode. In this study, carbon additives were introduced to achieve a rechargeable zinc slurry flow battery by minimizing the zinc plating on the bipolar plate that occurs during charging. When no carbon additive was present in the zinc slurry, the discharge current density was 24 mA center dot cm(-2)at 0.6 V, while the use of carbon additives increased it to up to 38 mA center dot cm(-2). The maximum power density was also increased from 16 mW center dot cm(-2)to 23 mW center dot cm(-2). Moreover, the amount of zinc plated on the bipolar plate during charging decreased with increasing carbon content in the slurry. Rheological investigation revealed that the elastic modulus and yield stress are directly proportional to the carbon content in the slurry, which is beneficial for redox flow battery applications, but comes at the expense of an increase in viscosity (two-fold increase at 100 s(-1)). These results show how the use of conductive additives can enhance the energy density of slurry-based flow batteries.
