Sodium-ion battery

8

Technology Description

The working principle for sodium-ion (Na-ion) batteries is the same as Li-ion - the difference is the change in the cation material (i.e. sodium instead of lithium). Na-ion is currently one of the most viable chemistries, capable of fulfilling some Li-ion functions, with the key advantage that it does not contain any lithium, thus avoiding lithium demand. Its leading anode and cathode materials are different from those used in Li-ion battery chemistries; they are composed of abundant, potentially safe and low-cost elements, containing no nickel or cobalt.

Relevance for Net Zero

This chemistry is important because it is the only current close to commercially viable chemistry which does not contain lithium, thus being able to reduce lithium demand. Its anode and cathode materials are composed of abundant and low-cost elements. Na-ion also does not contain any cobalt or nickel.
