The foundational building block of the batteries that supply power to everything from consumer electronics to electric vehicles is the lithium-ion cell.
Lithium-ion cells tend not to be standalone parts. They’re connected in series and parallel, forming a final assembly called a battery pack. But for each battery pack, the selected cell is what comes to define the lifespan and performance of the overall battery. The cell performance characteristics determine the size, weight, voltage, current, power, and environmental capabilities of the final battery pack.
