Lithium-ion battery - Wikipedia

3.6 / 3.7 / 3.8 / 3.85 V, LiFePO4 3.2 V. A lithium-ion battery or Li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging. Li-ion batteries use an intercalated lithium compound as the material at the positive

Do Lithium Ion Batteries Have A Shelf Life?-battery

There is no denying that someday, the Lithium-ion batteries will expire and you will have to get rid of them. By expired, it means the battery will no longer have a full life or charge cycle. Generally, when the self-discharge exceeds 20%, the batteries can no longer perform the same as it used to.
