How is a lithium-ion battery based on a physics-based cell design?
The cell design was first modeled using a physics-based cell model of a lithium-ion battery sub-module with both charge and discharge events and porous positive and negative electrodes. We assume that the copper foil is used as an anode and an aluminum foil is used as a cathode.
Can a battery pack be reconfigurable for individual cell replacement?
An alternative strategy would be making the battery pack reconfigurable for individual cell replacement, so that only less healthy cells would be replaced with newer cells, instead of replacing the entire battery pack [ 17 ].
Can Li-ion batteries be replaced?
The concept of cell replacement in Li-ion battery packs is relatively new, and despite some recent efforts to investigate this concept, the feasibility, in terms of economics and design, of cell replacement has not been well-studied.
Can cell replacement prolong the life of battery packs?
It was found that the cell replacement method can increase the total number of cycles of the battery packs, effectively prolonging the lifespan of the packs. It is also determined that this approach can be more economically beneficial than the current approach of simple pack replacement.
Can lithium ion batteries be reused?
The second scenario for reuse of lithium ion battery packs examines the problem of assembling a pack for less-demanding applications from a set of aged cells, which exhibit more variation in capacity and impedance than their new counterparts.
Does a battery pack have a Gaussian distribution?
Intrinsic variations in capacity and resistance have first been studied. New cells within a battery pack typically exhibit Gaussian distributions for Q and R, while aged cells display a wider spread over time, fitting Weibull distributions . Variations in E also notably influence battery packs' chargeable and dischargeable capacity .
