Estimate the Overall Equivalent Lithium Load of a Battery

We frequently see the chemical component lithium printed on batteries and we get started to question how significantly of it was loaded into the battery. Let us go straight to the strategy on how to compute its lithium content material. At first we must set up the adhering to data: first is the overall equivalent lithium content (ELC) for 1 mobile of the battery, second is the sum of cells in the battery. To compute the ELC (in grams), ELC is equal to the battery’s power (in ampere-hrs) multiply by .three then multiplied by the battery’s sum of cells.

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

Enable us get started by computing the ELC using the formula declared before. We know the energy score to be 8800 mAh (milliamps) and we need to convert it to Ah (amp hours) to utilize our formula and we have 8.eight Ah (8800 mAh equals eight.8 Ah). And so we are now ready to compute the HP Compaq 367759-001 battery a single mobile ELC which is eight.eight x .three equals two.sixty four grams.

Moreover, we are necessary to establish the sum of cells from our picked battery. The battery’s voltage was provided at 10.8V, we ought to divide that by the low voltage of 1 mobile then we get the sum of cells in collection as a consequence. Up coming is to divide the battery’s given potential (8800 mAh) by the nominal capacity of a single mobile and we get the resultant sum of cells in parallel. Now we can compute the sum of mobile in the battery by multiplying the collection and parallel benefits. Of Samsung 25R in HP 367759-001, the amount 18650 is regularly employed. It has a regular lower voltage of 3.6V and 2200 mAh nominal capability. 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 (ten.eight volts/three.six volts) equals twelve cells.

To conclude our endeavor to locate the overall ELC in HP Compaq 367759-001 battery, we want to do the subsequent computation. We have the information for one particular cell’s ELC at two.sixty four grams and the sum of cells in the battery is twelve cells. And lastly, compute the total equivalent lithium load of the battery by doing this calculation: 2.64g x twelve = 31.sixty eight grams.
