Below is the basic knowledge for the custom lithium ion battery packs (Li-Ion batteries) manufacturing.


Custom Lithium Ion Battery Packs (Li-Ion Batteries)
Lithium ion (Li-ion) battery packs are an advanced chemistry that provides increased performance over nickel- or lead-based chemistries at a price premium. Li-ion and lithium polymer batteries can have as much as twice the energy density of NiCd (nickel cadmium) batteries, have relatively low self-discharge rates, and are capable of high discharge currents.


Lithium Battery Pack Chemistries
Custom lithium battery packs are available in several chemistries:


Lithium cobalt oxide provides the greatest energy density
Lithium manganese offers greater safety with lower energy density than lithium cobalt oxide
Lithium iron phosphate provides high discharge rate capabilities, as well as long cycle and calendar life
Mixed cathodes can be used to optimize lithium rechargeable cells鈥?specific performance characteristics
Technical Specifications
Cell voltage: 3.2 鈥?3.7V (nominal)
Capacity: 500mAh to 5000mAh
Energy by volume: 270 WhL to 324 WhL
Energy by weight: 105 Whkg to 130 Whkg
Cycle life: 300 鈥?1000 cycles
Self-discharge rate: approx. 10% per month
Operating temperature range: -20掳C to 60掳C
Preferred charge method: constant voltageconstant current
Size: variable
Applications: military, industrial Mathieu Perreault Jersey Authentic , medical, consumer electronics
Note: Because of lithium鈥檚 inherent volatility and lithium ion鈥檚 high energy density, all custom lithium ion battery packs and cells require a special control circuit to manage the upper and lower voltage thresholds and to regulate operating currents and temperatures during charge and discharge.

ChargeDischarge Characteristics
In general, lithium ion charge circuits are of two-stage constant currentconstant voltage design. Fully discharged cells take constant current charges at a rate of 1C (1x the rated capacity), until reaching their set voltage of between 3.6 and 4.2 volts (depending on specific chemistry) Kyle Connor Jersey Authentic , a process which takes approximately one hour. The batteries鈥?chargers then switch to constant voltage, with the current tapering off until the batteries are fully charged鈥攁pproximately another two hours. The entire charging process is a fairly fast one, at about three hours. Lithium ion batteries may be removed from charge before they鈥檙e fully charged, with no side effects. However, Li-ion batteries cannot be trickle charged Mark Scheifele Jersey Authentic , as they do not tolerate overcharge conditions.

Custom Lithium Polymer Battery Packs
Lithium-ion-polymer batteries differ from lithium-ion batteries only in construction鈥攊t is not a unique and different chemistry. Li-polymer can be created in an array of chemistries, the most widely used of which is Li-cobalt. The difference in construction over conventional li-ion cells allows for lower cost, safer operation, and flexible packaging options; these custom lithium battery packs can be as thin as a credit card. These factors make custom lithium polymer battery packs and battery assemblies an increasingly popular choice for a wide range of applications.
