Estimate the Overall Equal Lithium Load of a Battery

We usually see the chemical component lithium printed on batteries and we get started to wonder how a lot of it was loaded into the battery. Allow us go right to the method on how to compute its lithium material. At first we have to build the pursuing info: 1st is the whole equivalent lithium articles (ELC) for 1 mobile of the battery, second is the sum of cells in the battery. To compute the ELC (in grams), ELC is equivalent to the battery’s electricity (in ampere-several hours) multiply by .3 then multiplied by the battery’s sum of cells.

Take 18650 Batteries of an HP Compaq 367759-001 battery with 10.8V, 8800 mAh, Li-ion technological specification as an illustration.

Let us get started by computing the ELC using the formula declared earlier. We know the energy score to be 8800 mAh (milliamps) and we ought to change it to Ah (amp hrs) to implement our system and we have 8.8 Ah (8800 mAh equals 8.8 Ah). And so we are now prepared to compute the HP Compaq 367759-001 battery 1 mobile ELC which is 8.8 x .3 equals two.64 grams.

Additionally, we are essential to build the sum of cells from our selected battery. The battery’s voltage was offered at 10.8V, we ought to divide that by the low voltage of a single mobile then we get the sum of cells in series as a consequence. Next is to divide the battery’s provided ability (8800 mAh) by the nominal capability of one particular cell and we get the resultant sum of cells in parallel. Now we can compute the sum of mobile in the battery by multiplying the sequence and parallel benefits. Of all the cells in HP 367759-001, the variety 18650 is frequently utilized. It has a common low 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 (10.8 volts/three.6 volts) equals twelve cells.

To conclude our endeavor to locate the complete ELC in HP Compaq 367759-001 battery, we need to do the subsequent computation. We have the knowledge for 1 cell’s ELC at 2.sixty four grams and the sum of cells in the battery is twelve cells. And finally, compute the total equivalent lithium load of the battery by executing this calculation: 2.64g x twelve = 31.sixty eight grams.
