The battery consists of current collectors, prussian blue anode, prussian blue cathodes, and an electrolyte layer.

The structure of a rechargeable sodium-ion battery structure is depicted in the figure below. Their sodium-ion batteries have a lower cost, a lower fire risk, a longer cycling lifetime, and are more environmentally friendly than commercial lithium-ion batteries, making them a future energy storage alternative to lithium-ion batteries. The open-framework nature of the cubic structure of prussian blue, which contains open channels and interstitial sites, enables rapid solid-state diffusion of sodium ions. Natron Energy develops sodium-ion batteries utilizing inexpensive prussian blue materials and natural abundance of sodium. Therefore, low-cost, high-performance, and low fire risk battery technology is required for the future energy storage. In addition, it is reported that several dozens of lithium-ion energy storage systems have resulted in explosions or fires. However, the high price of lithium-ion batteries prevents their widespread use as grid-scale energy storage devices. They are used to store energy on a grid that is integrated with intermittent solar and wind power. The lithium-ion battery technology has reached maturity.

Rechargeable batteries are strong candidates for storing intermittent solar and wind energy due to their small spatial footprint, mechanical simplicity, and siting flexibility. Battery working mechanism and performance.
