Lithium Ion Polymer Cell Voltage

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.

Lithium ion polymer cell voltage.

1 do not short circuit and do not overcharge lithium ion polymer cells. For example almost all lithium polymer batteries are 3 7v or 4 2v batteries. After that other packaging forms evolved including the flat pouch format. The cells use for electric bike bicycle tools solar project don t use for ev system.

Some cell manufacturers mark their li ion as 3 70v cell or higher. The lithium ion cells offer a nominal voltage that is pegged at 3 7 volts. High voltage batteries have only just begun to be used in large scale. 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.

3 the lithium polymer battery should be charged in a safe manner and never overcharged or overdischarged. 2 do not over discharge dent crush or burn the lithium polymer cells. 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. 4 do not try to solder directly to lithium polymer batteries.

The drawbacks are the need for protection circuits to prevent abuse as well as high price. If you take a look at your laptop battery you will see that it offers 11 1v which is equivalent to 3 7v. Lithium polymer cells have evolved from lithium ion and. What this means is that the maximum voltage of the cell is 4 2v and that the nominal average voltage is 3 7v.

100 original lg chem n2 1 3 7v 60ah polymer lipo lithium ion battery cell. The nominal voltage of normal voltage cells is at 3 6 3 7v while the nominal voltage of high voltage cells is at 3 8v or 3 85v. The nominal voltage of lithium ion is 3 60v cell. This offers a marketing advantage because the higher voltage boosts the watt hours on paper voltage multiplied by current equals watts.

Types of lithium ion batteries. Lithium ion polymer has its market niche in wafer thin geometries like batteries used in credit cards coupled with other similar applications. 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. Exceeding this voltage range results in premature aging and in safety risks due to the reactive components in the cells.
