Are lithium sulfur dioxide batteries rechargeable?
No, lithium-sulfur dioxide batteries are not rechargeable.
Lithium-sulfur dioxide batteries are a type of primary (non-rechargeable) battery that use a cathode made of sulfur dioxide and an anode made of lithium metal. When the battery is discharged, lithium ions move from the anode to the cathode while electrons flow through an external circuit, generating electrical energy.
However, once all the lithium in the anode has reacted with the sulfur dioxide in the cathode, the battery cannot be recharged because the chemical reaction is irreversible. Therefore, lithium-sulfur dioxide batteries are typically used in applications where long shelf life and high energy density are important, but rechargeability is not required.
