Despite being frequently used as a shorthand for lithium-ion batteries, the term "lithium battery" really refers to a primary lithium battery, which is both non-rechargeable and disposable and contains just pure lithium metal.
Typically, a lithium metal battery employs a non-aqueous electrolyte solution and lithium metal or its alloy as the negative electrode material and manganese dioxide as the positive electrode material.
The manufacturing, storage, and use of lithium metal have very strict environmental requirements because of the metal's highly reactive chemical properties. As a result, lithium batteries have not been utilized recently.
