How to determine lithium battery versus the internal battery cells
How do you determine how many cells are in a Lithium battery?
My assumption is for customer travel and the present limits are;  

• MAX Lithium per cell 20Wh
• MAX Lithium per battery 100Wh    

The battery in question.


LP635940 Lithium Polymer Battery
3.7V @ 1.8Ah typ. capacity at 0.2C rate
= 6.66 Wh  which is less than MAX per cell limit.

How many cells in package?
Only 1.
Not because of capacity but because of construction method.   

What are cells?
- discrete (separate) manufactured items.   

How many items here?
1    

How is it made?
Many recurring thin layers of {conductor mesh , electrolyte,  insulator}.
