Abstract:
A sodium-ion battery includes an electrode having a crystalline active material represented by formula units that intercalate and/or deintercalate more than two charge carriers during operation of the battery. In some instances, the active material that experiences a volume change of less than 6.0%, 4.0%, or even 2.0% when the active material intercalates more than two charge carriers during operation of the battery.
