A Modified Multiphysics model for Lithium-Ion batteries with a LixNi1/3Mn1/3Co1/3O2 electrode

Lithium-Ion Batteries lack performance and are costly for applications such as electric vehicles and electric energy storage systems. Multiphysics based battery models are one of the engineering tools to enhance their performance. In this regard, simulations have not only to provide qualitative but also quantitative valuable information. Our work focuses on the characterization and modelling of LixNi1/3Mn1/3Co1/3O2 based cells which has not been fully addressed yet. First, we present a modified multiphysics model compared to the conventional porous electrode theory for simulating these type of cells. The correspondence with experimental results is satisfactory but the model fails to accurately predict the voltage drop at high current rates. (c) 2015 Elsevier Ltd. All rights reserved.
