Like all batteries the Li-ion battery also has a voltage and capacity rating. The nominal voltage rating for all lithium cells will be 3.6V, so you need higher voltage specification you have to combine two or more cells in series to attain it. By default all the lithium ion cells will have a nominal voltage of only ~3.6V.
Lithium ion cell or battery means a rechargeable electrochemical cell or battery in which the positive and 38.3.3 When a cell or battery type is to be tested under this sub-section, the number and condition of cells and batteries of each type to be tested are as follows: (a) When testing primary cells and batteries under tests 1 to 5 the
18650 Cells: 18650 cells are among the most widely used lithium-ion cell sizes. They measure 18mm in diameter and 65mm in length, hence the name. Capacity ranges from 1000mAh up to 3500mAh.

Another great thing about 18650 lithium-ion cells is their power density. While a typical AA battery contains only about 3.9 watt-hours of energy, a 18650 lithium-ion cell can store 13 watt-hours or more. This is no surprise, as energy density figures for modern lithium-ion cells are between 100 and 265 watt-hours per kilogram. Their

An 18650 battery is a type of lithium-ion rechargeable battery. The numbers "18650" refer to the battery''s dimensions: it is 18mm in diameter and 65mm in length. 18650 batteries are commonly used in electronic devices such as laptops and flashlights, as well as in electric vehicles and other high-power applications.

For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.
