Sodium batteries are a type of rechargeable battery that utilizes sodium ions as the charge carriers instead of lithium ions, which are commonly used in lithium-ion batteries. These batteries generally comprise a sodium-based electrolyte, an anode made from materials such as sodium metal or carbon, and a cathode made from compounds like sodium cobalt oxide or sodium manganese oxide.
Sodium batteries are gaining attention due to sodium’s abundance and low cost compared to lithium, making them potentially more sustainable and economically viable for large-scale energy storage applications. They aim to provide a similar energy density and performance to lithium-ion batteries while offering advantages in terms of raw material availability and safety.
Research and development are ongoing to improve the efficiency, lifespan, and overall performance of sodium batteries, as well as to explore their applications in renewable energy storage, electric vehicles, and other energy management systems.
Researchers in the United States have achieved a significant breakthrough in the development of solid-state, anode-free sodium batteries. This promising advancement not only offers enhanced levels of safety but also…
