Lithium-ion Batteries

Lithium-ion Battery. (Li-ion) A Battery that uses lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode).

The advantage of using a Li-ion battery is that they have no memory effect and a slow loss of charge when not in use. Capacity loss is approximately 5% per month compared to over 30% per month for NiMH and 20% per month for NiCd.

The "C"-type 3-V lithium cells are today the most commonly-used type in quartz watches, calculators. Its package's size is identified by a three-to-four digit code, preceded by the letter "R" to indicate a round cell. The first 1 to 2 digits indicate the outer breadth of the battery (in millimeters, rounded down), and the last two digits indicate the overall height (in tenths of millimeters, rounded down).

ISO/IEC 83-3 diameter codes:
4 = 4.8+0-0.15 mm
5 = 5.8+0-0.15 mm
6 = 6.8+0-0.15 mm
7 = 7.9+0-0.15 mm
9 = 9.5+0-0.15 mm
10 = 10.0+0-0.20 mm
11 = 11.6+0-0.20 mm
12 = 12.5+0-0.25 mm
16 = 16+0-0.25 mm
20 = 20+0-0.25 mm
23 = 23+0-0.50 mm
24 = 24.5+0-0.50 mm

Height Codes
used with 16 to 24 mm diameter batteries:
12 = 1.20+0-0.20 mm
16 = 1.60+0-0.20 mm
20 = 2.00+0-0.25 mm
25 = 2.50+0-0.50 mm
30 = 3.00+0-0.50 mm
36 = 3.60+0-0.50 mm
50 = 5.00+0-0.50 mm

Lithium-ion Batteries come in a number of shapes and sizes.
However this page only covers Li-ion coin cells.
Additional styles: [Coin Battery, Button Battery]
There are two styles of Tabbed Li-ion coin cells, both surface mount and pinned (through-hole).
Also Lithium-ion Batteries may be encapsulated and hermetically sealed
Lithium Polymer Ion batteries use a gel electrolyte to replace the traditional liquid electrolyte and normally are formed into a thin styles.
A Lithium iron phosphate battery is a style of rechargeable battery in a AAA format.

Lithium-ion batteries have a nominal open-circuit voltage of 3.6V and typical charging voltage of 4.2V.
