How many grams of lithium are in a 1320 [mah] cell phone battery? note that [mah] is a unit of charge.

0.396 grams of lithium

Explanation:

Lithium-ion batteries have the main feature of using lithium salts as a "bridge" between the positive pole (anode) to the negative (cathode) to allow the passage of energy that will give life to our device. In the case of lithium polymer batteries, the difference is that the lithium salt is contained in a polymer, or gel, to keep it safe from spills.

In both cases, when the battery is discharging, lithium ions travel from the cathode to the anode through their "bridges" to supply the energy until all the ions are in the anode, it is at this time when the battery is out of stock The ions travel in the opposite direction during charging (from the anode to the cathode).

The calculation used to determine the amount of lithium that the lithium cell batteries have is as follows:

0.3 x amp hour capacity = g of lithium

where amp hour = Ah

In our case:

0.3 x 1.32 = 0.396 g of lithium

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
