Project R-14109

A multiscale experimental/modeling approach for the study of porous electrodes in lithium-ion batteries (MAPBAT) (Research)

Driven by the pivotal role of batteries in the rollout of zero-emission mobility and the storage of the intermittent renewable energy, experts have forecasted a 14-fold increase in the global demand for the batteries by 2030. lithium-ion batteries (LIBs), as the most promising candidate among battery technologies, have been the focus of attention for few decades. Despite the current improvements in developing more efficient LIBs, there still exists a great demand of higher energy and power density, longer durability, and lower cost. Physics-based models are precious tools to understand the battery behavior and facilitate the development of new and optimization of existing battery chemistries. However, Dozens of parameters appear in a physics-based model which represent the kinetics and transport phenomena between two extreme length scales: 1) single-particle level, 2) porous-electrode level. This project aims to develop a multi-scale characterization platform for an unequivocal parametrization of the physics-based models using orthogonal experiments at different length scales. Multi-barrel micro electrode, micro-band, micro-channel, and micro-cavity setups are designed to study the battery behavior at the single- and many-particle levels. Parallel experiments on the porous electrode scale, will provide precious set of parameters to fine tune the physics-based models. while this project focuses on the LIBs, the methodology can be extended for other battery technologies.
