dc.description.abstract The thesis presents a modeling framework for simulating three dimensional effects in lithium -ion batteries . This is particularly important for understanding the performance of large scale batteries used under high power conditions such as in hybrid electric vehicle applications . While 1D approximations may be sufficient for the smaller scale batteries used in cell phones and laptops , they are severely limited when scaled up to larger batteries , where significant 3D gradients can develop in concentration , current , temperature , and voltage . Understanding these 3D effects is critical for designing lithium -ion batteries for improved safety and long term durability , as well as for conducting effective design optimization studies . The model couples an electrochemical battery model with a thermal model to understand how thermal effects will influence electrochemical behavior and to determine temperature distributions throughout the battery . Several modeling example results are presented including thermal influences on current distribution , design optimization of current collector thickness and current collector tab placement , and investigation of lithium plating risk in three dimensions . en_US
