Sodium battery development is becoming a focus of interest for sustainability because of its potential cost and availability of materials. However, it is still in its early stages of development and not widely used in homes. A knowledge of the working principle of the sodium-ion battery, the differences between such battery and the present battery systems, and what the sodium-ion battery might provide in the future gives a clearer idea of the current evolution of energy storage systems.
What Is a Sodium Ion Battery and how it works?
A Sodium Ion Battery is an energy storage technology that uses sodium ions moving between the battery electrodes during charging and discharging. Although the principle of operation is similar to most other rechargeable battery systems in use today, sodium is the main charge carrier as opposed to lithium.
Growing interest in sodium ions batteries has been driven by the fact that sodium is much more abundant worldwide than lithium and could enable alternative strategies for the development of future energy storage systems. But battery performance, production scale and commercialization readiness are important to consider.
