Heterogeneous lithium battery cells
This model describes the behavior of a lithium-ion battery unit cell modeled using an idealized heterogeneous three-dimensional geometry. In contrast to the typical homogenized approach for describing porous electrodes, heterogeneous models define the actual shapes of. . Heterogeneous aging of lithium-ion (Li-ion) battery cells within a battery pack is a major challenge that limits the pack's overall performance, safety, and life. Variations in cell degradation rates lead to nonuniform charge/discharge behavior among cells in a pack, accelerated aging in some cells. . In this paper, an electrochemical–mechanical coupling model is established for a two-dimensional, fully heterogeneous lithium-ion battery. Accordingly, this work introduces a. .
