Some cell manufacturers mark their li ion as 3 70v cell or higher.
Lithium ion polymer cell voltage.
For example almost all lithium polymer batteries are 3 7v or 4 2v batteries.
Lithium polymer cells have evolved from lithium ion and.
The lithium ion cells offer a nominal voltage that is pegged at 3 7 volts.
This offers a marketing advantage because the higher voltage boosts the watt hours on paper voltage multiplied by current equals watts.
The nominal voltage of lithium ion is 3 60v cell.
Exceeding this voltage range results in premature aging and in safety risks due to the reactive components in the cells.
If you take a look at your laptop battery you will see that it offers 11 1v which is equivalent to 3 7v.
Citation needed design origin and terminology.
The cells use for electric bike bicycle tools solar project don t use for ev system.
What this means is that the maximum voltage of the cell is 4 2v and that the nominal average voltage is 3 7v.
The nominal cell voltage of 3 60v can directly power mobile phones tablets and digital cameras offering simplifications and cost reductions over multi cell designs.
1 do not short circuit and do not overcharge lithium ion polymer cells.
As the battery is used the voltage will drop lower and lower until the minimum which is around 3 0v.
2 do not over discharge dent crush or burn the lithium polymer cells.
Lipo cells follow the history of lithium ion and lithium metal cells which underwent extensive research during the 1980s reaching a significant milestone with sony s first commercial cylindrical li ion cell in 1991.
High voltage batteries have only just begun to be used in large scale.
4 do not try to solder directly to lithium polymer batteries.
Lithium ion cells are susceptible to stress by voltage ranges outside of safe ones between 2 5 and 3 65 4 1 4 2 or 4 35v depending on the components of the cell.
Li polymer battery are made of soft aluminum plastics compound packaging internal is half solid polymers discharge stability high efficiency the internal resistance small safety performance is better and has.
After that other packaging forms evolved including the flat pouch format.

The lithium ion polymer cells used in th is study were eig eplb c020 lithium nickel manganese cobalt oxide based catho de and graphite based anode with 3 6 v nominal voltage and 20 ah.
Lithium ion polymer lipo battery cells with normal voltages are fully charged at 4 2v while high voltage cells are at 4 35v.
Lithium ion polymer has its market niche in wafer thin geometries like batteries used in credit cards coupled with other similar applications.
