How is the “equivalent lithium content” for a lithium ion cell and battery determined?
Equivalent lithium content means, for a lithium ion cell, the product of the rated capacity, in ampere-hours of a lithium ion cell times 0.3. The total equivalent lithium content is expressed in grams (g). The equivalent lithium content of a battery equals the sum of the grams (g) of equivalent lithium content contained in the component cells of the battery. Example: A lithium ion cell in a laptop battery pack may have a rated capacity of 2.2 ampere-hours. Applying the conversion factor of 0.3, a battery pack with 9 of these cells contains 5.94 grams of equivalent lithium content.
