Detailed Explanation:
Technology batteries, most commonly those using lithium-ion technology, operate through a process of electrochemical reactions. At the heart of the battery are two electrodes – an anode (negative) and a cathode (positive) – separated by an electrolyte. The electrolyte is a material that allows ions (electrically charged atoms) to move between the electrodes, but prevents electrons from flowing directly between them. This controlled movement of ions and electrons is what generates electricity.
During discharge (when the battery powers a device), lithium ions travel from the anode to the cathode through the electrolyte. As they move, they carry electrons with them, creating an electrical current that flows through the external circuit powering the device. The chemical reactions involved cause the anode to oxidize (lose electrons) and the cathode to reduce (gain electrons).
During charging, the process is reversed. An external power source forces electrons into the anode and pulls them from the cathode. This causes the lithium ions to migrate back to the anode, restoring the battery to its original state. The specific chemistry and materials used in the electrodes and electrolyte determine the battery's voltage, capacity, and lifespan. Different types of batteries exist (e.g., lead-acid, nickel-cadmium, etc.), each with unique electrochemical characteristics.
Simplified Explanation:
A battery works by using chemical reactions to create an electrical current. It has two ends, a positive and negative, and when you connect these, the chemicals react, causing electrons to flow, creating electricity. Recharging reverses this process.

Redox flow batteries (RFBs) are a type of electrochemical energy storage device that differ significantly from conventional batteries. Instead of storing energy within a solid electrode material like lithium-ion batteries, RFBs store energy in the form of chemical energy within two separate liquid electrolyte solutions, each containing dissolved electroactive species. These electrolytes are stored in external tanks and pumped through a cell stack containing an electrode pair (anode and cathode). During discharge, the electroactive species in each electrolyte undergo redox reactions (reduction and oxidation), transferring electrons through an external circuit to generate electricity. The state of charge (SOC) is determined by the concentration difference of the electroactive species in the two electrolytes. The key components are:
The reversible nature of the redox reactions allows for repeated charging and discharging cycles, making RFBs well-suited for applications requiring long cycle life and deep discharge capabilities. Because energy storage and power are decoupled (tank size determines energy capacity, cell stack size determines power), RFBs offer modularity and scalability, making them suitable for both grid-scale and smaller applications. Common electrolytes include vanadium, iron, zinc, and organic redox-active molecules.
However, RFBs generally exhibit lower energy density compared to lithium-ion batteries, meaning they require larger tanks for a given energy capacity. Furthermore, their cost can be higher, and their power density can be relatively lower compared to other battery technologies.
Redox flow batteries store energy in liquid electrolytes, not solid electrodes like most batteries. They pump these liquids through a cell stack where chemical reactions produce electricity. The energy capacity depends on the amount of liquid, while the power depends on the size of the cell stack.
