The Status and Challenges of Molecular Design for Organic Electroactive Molecule-Based Electrolytes for Redox Flow Batteries

The redox flow battery has gotten a lot of interest in recent decades as a large-scale energy storage technology with a lot of potential. Redox molecules, which allow RFBs to convert chemical energy to electric energy, have sparked interest in a variety of sectors, including energy storage, functional materials, and synthetic chemistry. Inorganic metal ions are the most commonly employed electroactive molecules, but most of them are scarce and expensive, preventing RFBs from being widely used. As a result, there is a pressing need to develop novel, low-cost electroactive chemicals for the commercialization of RFBs. Due to their inherent qualities in the field, RFBs based on organic electroactive compounds such as quinones and nitroxide radical derivatives have been explored and have been a hot focus of research. The development of renewable and clean energy has become an essential concern in many research domains, particularly in energy source and eco-environmental studies, to reduce the use of fossil fuels and CO2 emissions, which cause global warming. Solar and wind energy are both ecologically benign and seen as viable future alternative energy sources. However, the inherent intermittency and unpredictability of these renewable resources limit their market adoption. Energy storage technology is critical for the spread of renewable energy since it is an effective solution for intermittency.
