Towards electrochemical-performance evaluation of fiber-based batteries: Fiber-arrangement-based method and FE² multiscale framework

Conventional battery models (e.g., Pseudo-2D model) were developed especially for particle-based battery electrodes and have limitations in addressing the newly-emerging fiber-based ones. This thesis proposes numerical tools for efficient property evaluation of fiber-based electrodes and for multiscale simulation of battery electrochemical...

Tensorial effective transport properties of Li-ion battery separators elucidated by computational multiscale modeling

Existing battery modeling works have limitations in addressing the dependence of transport properties on local field variations and characterizing the response of anisotropic media. These limitations are tackled by means of a nested finite element (FE²) multiscale framework in which microscale simulations are employed to...
