We often see the chemical component lithium printed on batteries and we commence to question how considerably of it was loaded into the battery. Allow us go right to the method on how to compute its lithium articles. At first we have to create the subsequent information: very first is the complete equivalent lithium content (ELC) for one cell 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 energy (in ampere-hrs) multiply by .3 then multiplied by the battery’s sum of cells.
Get the circumstance of an HP Compaq 367759-001 battery with ten.8V, 8800 mAh, Li-ion technical specification as an example.
Allow us start by computing the ELC employing the formula declared earlier. We know the electricity ranking to be 8800 mAh (milliamps) and we should change it to Ah (amp hrs) to utilize our formulation and we have eight.8 Ah (8800 mAh equals eight.8 Ah). And so we are now all set to compute the HP Compaq 367759-001 battery a single mobile ELC which is eight.eight x .three equals two.sixty four grams.
Additionally, 18650 Battery Vape are necessary to set up the sum of cells from our selected battery. The battery’s voltage was provided at ten.8V, we must divide that by the lower voltage of one particular cell then we get the sum of cells in sequence as a consequence. Following is to divide the battery’s given potential (8800 mAh) by the nominal capability of one 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 series and parallel results. Of all the cells in HP 367759-001, the variety 18650 is regularly utilized. It has a regular reduced voltage of three.6V and 2200 mAh nominal capability. We are now all set to compute the sum of cells in the HP Compaq 367759-001 battery with this: (8800 mAh/2200 mAh) x (ten.8 volts/three.six volts) equals twelve cells.
To conclude our endeavor to locate the overall ELC in HP Compaq 367759-001 battery, we need to do the subsequent computation. We have the knowledge for one particular cell’s ELC at two.sixty four grams and the sum of cells in the battery is 12 cells. And lastly, compute the total equivalent lithium load of the battery by carrying out this calculation: two.64g x twelve = 31.68 grams.
