How does a redox flow battery work?5 answersA redox flow battery works by utilizing two electrolyte solutions, one at the positive electrode and one at the negative electrode, which flow through an electrochemical cell. The electrolyte solutions store and release energy by undergoing redox reactions. The battery consists of two half-cells, with a cathode in one half-cell and an anode in the other half-cell, separated by an ion exchange membrane. The electrolyte solutions, which can be aqueous or non-aqueous, contain redox species and metal ions. The flow of the electrolyte solutions is controlled by an electrolyte flow path, which connects the battery cell to an electrolyte tank. The battery may also include a metal-ion-conductive membrane to prevent crossover of redox species. The electrolyte solutions circulate through the cell using positive and negative electrode circulating means. The battery may also have a redox flow stack, consisting of multiple flow frames, each containing bipolar plates, porous electrodes, and ion-selective membranes.
How can we use batteries to store renewable energy?3 answersBatteries are essential for storing renewable energy, such as solar or wind power, to be used during periods of scarcity. A dynamic Li-ion battery model for renewable purposes has been developed, which takes into account both charge and discharge processes, unlike most models found in the literature. Another approach is to reuse second life electric vehicle batteries as an energy storage system, which can compensate for variations in energy and power requirements. Lithium-ion batteries (LiBs) have been a popular choice for energy storage due to their high energy density and good charge-discharge properties, although they still face safety and stability issues. Redox flow batteries, particularly iron-based ones, are also of interest for grid-level energy storage. The challenge lies in developing cost-effective and eco-friendly energy storage alternatives to address the current energy crisis.
