CUSTOM LI-POLYMER BATTERY PACKS


Lithium-ion-polymer batteries differ from lithium-ion batteries only in construction—it 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; cells as thin as a credit card are possible. The combination of these factors makes custom lithium polymer battery packs and battery assemblies an increasingly popular choice for a wide range of applications.
