What is a lithium battery cell？
For example, we use a single lithium cell and a battery protection plate to make a 3.7V battery with a storage capacity of 3800mAh to 4200mAh, while if you want a larger voltage and storage capacity lithium battery, it is necessary to use several lithium cells in series and parallel with a well-designed battery protection plate. This will make up the desired lithium battery.
A battery made from a combination of several cells
If several of these cells are combined to form a battery pack with a higher voltage and storage capacity, then the cell can be a battery unit or, of course, a single cell can be a battery unit;
Another example is the lead-acid battery, a battery can be called a battery unit, this is because the lead-acid battery is a single whole, in fact, is not removable, of course, can also be based on certain technology, with a reasonably designed bms system, multiple single 12V lead-acid battery, according to the way of series and parallel connection, combined into the desired voltage and storage capacity size of the large battery (battery pack).
What does battery cell mean?
First of all, it should be clear what type of battery this one belongs to, whether it is a lead-acid or lithium battery, or a dry cell, etc., and only then can we go further to understand the following relationship between the definition of a battery and the definition of a quantum battery.
A cell = a battery, but a battery does not necessarily equal a cell;
A battery cell must be a combination of several cells to form a battery pack, or a single cell; any battery, regardless of size, is a combination of one or more battery cells.
