How does a sodium ion battery work?

Electrolyte: The electrolyte is a sodium salt (e.g., NaPF₆) dissolved in a solvent, which allows sodium ions to move between the anode and cathode during the charge and discharge cycles.

Components of a Sodium-Ion Battery: Anode: Often composed of hard carbon or other materials, this is where sodium ions are stored during the charging process. Cathode: Made of various materials, including layered oxides, polyanionic compounds, and Prussian blue analogs, this is where the sodium ions move to during discharge.

What happens when a battery is discharged?

When the battery is discharged, sodium ions move from the anode to the cathode through an electrolyte - a substance composed of free ions that functions as an electrical conductor - resulting in the potential difference that produces the current.

Can a Na ion battery be discharged to 0 V?

Or may lead to fire/explosion due to internal short circuit caused by the deposition of metallic copper on the cathode. But for Na-ion batteries, the anode uses a lighter and cheaper aluminum current collector substrate, which enables it to be safely discharged to 0 V.

What happens when sodium ions leave a cathode?

As the sodium ions leave the cathode, electrons are stripped from them and flow back through the external circuit to the anode. At the anode, these electrons recombine with the sodium ions, storing energy in the process. The electrolyte plays a crucial role in the transport of sodium ions between the anode and the cathode.
