Development of a rechargeable Zn-air redox flow battery






  • The main objective of the project is to design, develop and characterise the different components that form part of a zinc-air redox flow battery, in order to create a prototype for a rechargeable battery that can store surplus energy.

    Batteries based on redox flow systems are an alternative to traditional secondary batteries such as lithium ion, and, as they present a high theoretical energy density, they can be used in stationary applications. In addition, the use of zinc and oxygen from the air as anodic and cathodic materials constitutes a major advantage over batteries based on other technologies, due to the abundance of these materials in nature, together with their low cost. The combination of this type of device with renewable energy sources (such as solar and wind energy) will make it possible to store clean energy and will avoid the discharge of surplus energy, while guaranteeing the stability of the system.
