Better design and integration of lithium-ion batteries can help lower costs of plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs). The form factor of the electrode is an important design variable that directly relates to the usable power density of the cell and also affects the cost. This work, currently in progress, looks at performing sensitivity analyses on the effects of varying the electrode thicknesses of lithium-ion batteries for different electrified vehicles (EVs, plug-ins of different all-electric-ranges and battery electric vehicles) based on their power and energy density requirements, with the overall cost of production of the batteries for that EV application as a key output parameter. This is being done using the software Battery Design Studio. It will thereby estimate and identify the least cost battery packs for any EV application, which will be of use to automakers. Policy makers can also relate to this study while incentivizing different battery pack designs and sizes, which will ensure that lithium-ion batteries are more economically and usefully implemented.
