Estimate the Whole Equivalent Lithium Load of a Battery

We typically see the chemical factor lithium printed on batteries and we start to question how considerably of it was loaded into the battery. Allow us go immediately to the approach on how to compute its lithium content material. To begin with we must create the following data: 1st is the overall equal lithium material (ELC) for a single mobile 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 energy (in ampere-hours) multiply by .3 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 technical specification as an instance.
Allow us get started by computing the ELC using the method declared previously. We know the electrical power score to be 8800 mAh (milliamps) and we must transform it to Ah (amp hrs) to implement our formula and we have 8.8 Ah (8800 mAh equals 8.eight Ah). And so we are now prepared to compute the HP Compaq 367759-001 battery a single cell ELC which is eight.eight x .3 equals 2.64 grams.
18650 Batteries
Moreover, we are required to set up the sum of cells from our selected battery. The battery’s voltage was presented at ten.8V, we should divide that by the reduced voltage of one particular cell then we get the sum of cells in series as a end result. Up coming is to divide the battery’s provided capability (8800 mAh) by the nominal capacity of 1 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 collection and parallel benefits. Of all the cells in HP 367759-001, the number 18650 is often utilised. It has a regular minimal voltage of three.6V and 2200 mAh nominal potential. 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.8 volts/3.six volts) equals 12 cells.
To conclude our endeavor to discover the overall ELC in HP Compaq 367759-001 battery, we need to have to do the subsequent computation. We have the information for a single cell’s ELC at two.64 grams and the sum of cells in the battery is twelve cells. Finally, compute the total equal lithium load of the battery by carrying out this calculation: two.64g x twelve = 31.68 grams.
