Abstract EN
Lithium ion batteries have conventionally been manufactured in small capacities but large volumes for consumer electronics applications.
More recently, the industry has seen a surge in the individual cell capacities, as well as the number of cells used to build modules and packs.
Reducing cell-to-cell and lot-to-lot variations has been identified as one of the major means to reduce the rejection rate when building the packs as well as to improve pack durability.
The tight quality control measures have been passed on from the pack manufactures to the companies building the individual cells and in turn to the components.
This paper identifies a quantitative procedure utilizing impedance spectroscopy, a commonly used tool, to determine the effects of material variability on the cell performance, to compare the relative importance of uncertainties in the component properties, and to suggest a rational procedure to set quality control specifications for the various components of a cell, that will reduce cell-to-cell variability, while preventing undue requirements on uniformity that often result in excessive cost of manufacturing but have a limited impact on the cells' performance.
