Estimate the Total Equivalent Lithium Load of a Battery

We often see the chemical element lithium printed on batteries and we start to ponder how considerably of it was loaded into the battery. Allow us go straight to the technique on how to compute its lithium material. Originally we need to build the subsequent data: initial is the overall equivalent lithium content (ELC) for one particular cell of the battery, 2nd 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 .three then multiplied by the battery’s sum of cells.


Just take the circumstance of an HP Compaq 367759-001 battery with 10.8V, 8800 mAh, Li-ion complex specification as an instance.

Let us begin by computing the ELC making use of the method declared previously. We know the power score to be 8800 mAh (milliamps) and we must convert it to Ah (amp several hours) to apply our system and we have 8.8 Ah (8800 mAh equals eight.eight Ah). And so we are now all set to compute the HP Compaq 367759-001 battery 1 mobile ELC which is 8.8 x .3 equals 2.64 grams.

Furthermore, we are required to build the sum of cells from our picked battery. 18650 Batteries was offered at ten.8V, we should divide that by the lower voltage of one particular cell then we get the sum of cells in series as a consequence. Up coming is to divide the battery’s offered potential (8800 mAh) by the nominal functionality of a single mobile and we get the resultant sum of cells in parallel. Now we can compute the sum of cell in the battery by multiplying the series and parallel benefits. Of all the cells in HP 367759-001, the quantity 18650 is frequently employed. It has a normal lower voltage of 3.6V and 2200 mAh nominal capacity. We are now completely ready to compute the sum of cells in the HP Compaq 367759-001 battery with this: (8800 mAh/2200 mAh) x (10.8 volts/3.6 volts) equals 12 cells.

To conclude our endeavor to uncover the overall ELC in HP Compaq 367759-001 battery, we need to do the subsequent computation. We have the information for one cell’s ELC at two.64 grams and the sum of cells in the battery is 12 cells. And lastly, compute the complete equal lithium load of the battery by performing this calculation: two.64g x 12 = 31.68 grams.
