Characteristics of NaPF6 based electrolytes for sodium-ion batteries

Sodium-ion batteries are currently emerging as an alternative to lithium-ion batteries due to the lower costs and the better availability of sodium compared to lithium. The working principle of a sodium-ion battery is very similar to that of a lithium-ion battery, shuttling ions between the positive and negative electrode with the help of the electrolyte. Due to the incompatibility of sodium ions and graphite, hard or soft carbons are commonly applied as anode materials. As positive electrodes serve sodium-containing compounds, such as prussian white. The energy density of sodium-ion batteries is typically lower than that of lithium-ion batteries and thus sodium-ion batteries are considered in particular for stationary energy storage or for electric vehicles of the entry level class.

Application fields of electrolytes containing NaPF6

The electrolyte in a sodium-ion battery typically contains a sodium salt that is dissolved in a solvent mixture of linear and cyclic carbonates. Sodium hexafluorophosphate is the most promising salt for commercial cells due to its well-balanced properties regarding thermal stability, dissociation, and current collector passivation. Sodium perchlorate is another commonly used salt in academia, but its wide commercial applications is hindered by explosion hazards.
