We usually see the chemical component lithium printed on batteries and we start to surprise how considerably of it was loaded into the battery. Permit us go right to the technique on how to compute its lithium articles. Originally we need to establish the pursuing info: 1st is the overall equal lithium content material (ELC) for a single 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 electricity (in ampere-hours) multiply by .three then multiplied by the battery’s sum of cells.
Consider the scenario of an HP Compaq 367759-001 battery with 10.8V, 8800 mAh, Li-ion specialized specification as an illustration.
Let us begin by computing the ELC making use of the formulation declared before. We know the energy score to be 8800 mAh (milliamps) and we should transform it to Ah (amp hrs) to implement our formulation and we have eight.eight Ah (8800 mAh equals eight.eight Ah). And so we are now ready to compute the HP Compaq 367759-001 battery 1 cell ELC which is 8.8 x .three equals 2.sixty four grams.
Additionally, we are required to create the sum of cells from our selected battery. The battery’s voltage was presented at ten.8V, we ought to divide that by the low voltage of 1 cell then we get the sum of cells in series as a consequence. Up coming is to divide the battery’s offered capacity (8800 mAh) by the nominal ability of one particular 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 series and parallel outcomes. Of all the cells in HP 367759-001, the number 18650 is frequently utilized. It has a common reduced voltage of 3.6V and 2200 mAh nominal capability. We are now prepared 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 uncover the total ELC in HP Compaq 367759-001 battery, we require to do the subsequent computation. We have the data for 1 cell’s ELC at two.64 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.
