Estimate the Overall Equal Lithium Load of a Battery

We frequently see the chemical aspect lithium printed on batteries and we begin to ponder how significantly of it was loaded into the battery. Permit us go right to the strategy on how to compute its lithium articles. To begin with we should establish the adhering to knowledge: very first is the whole equivalent lithium content material (ELC) for a single mobile of the battery, next is the sum of cells in the battery. To compute the ELC (in grams), ELC is equivalent to the battery’s electrical power (in ampere-hrs) multiply by .3 then multiplied by the battery’s sum of cells.


Get the scenario of an HP Compaq 367759-001 battery with 10.8V, 8800 mAh, Li-ion technical specification as an case in point.

Enable us get started by computing the ELC making use of the method declared before. We know the electrical power score to be 8800 mAh (milliamps) and we ought to transform it to Ah (amp hours) to apply our formulation and we have 8.eight Ah (8800 mAh equals 8.eight Ah). And so we are now prepared to compute the HP Compaq 367759-001 battery a single mobile ELC which is 8.eight x .3 equals 2.64 grams.

Moreover, we are essential to create the sum of cells from our decided on battery. The battery’s voltage was given at ten.8V, we ought to divide that by the lower voltage of one mobile then we get the sum of cells in sequence as a consequence. Up coming is to divide the battery’s offered potential (8800 mAh) by the nominal capacity of a single cell and we get the resultant sum of cells in parallel. Now we can compute the sum of cell in the battery by multiplying the sequence and parallel outcomes. Of all the cells in HP 367759-001, the amount 18650 is frequently employed. It has a regular low voltage of three.6V and 2200 mAh nominal capacity. Vapcell 21700 are now completely ready to compute the sum of cells in the HP Compaq 367759-001 battery with this: (8800 mAh/2200 mAh) x (ten.8 volts/3.six volts) equals twelve cells.

To conclude our endeavor to uncover the whole ELC in HP Compaq 367759-001 battery, we need to have to do the subsequent computation. We have the info for a single cell’s ELC at two.sixty four grams and the sum of cells in the battery is 12 cells. And finally, compute the overall equal lithium load of the battery by performing this calculation: 2.64g x 12 = 31.sixty eight grams.
