It is our pleasure to invite you to the Applied Computational Science (ACOS) symposium that will take place on 30 October 2019 at the Dutch Institute for Fundamental Energy Research (DIFFER), located at the campus of the Eindhoven University of Technology (TU/e).
Title: Multiscale modeling of nanostructured electrodes and interfaces in Li-ion batteries
Speaker: Dmitry Bedrov (Department of Materials Science and Engineering, University of Utah)
Time: Oct. 10, 2019, 09:30–11:00 (coffee from 09:00)
Location: Differ, Alexander-zaal
Abstract
In this talk I will discuss interdisciplinary efforts on multiscale modeling of electrochemical devices undertaken at the Alliance for Computationally-guided Design of Energy Efficient Electronic Materials (CDE3M). Specifically, I will focus on our recent results in modeling components of Li-ion batteries, including solid electrolyte interphase (SEI), SEI/electrolyte interfaces, and nanostructured Si anodes. The coupling of electrochemical and mechanical processes inside electrodes and at electrode/SEI interfaces is one of the key challenges that has to be addressed in order to provide efficient materials-by-design of novel batteries. Most of the current modeling tools only consider these system at the continuum level. We have focused on the development of multiscale modeling tools that allow to couple the atomic, molecular and nanoscale electrochemical and mechanical processes with continuum level modeling. This talk will discuss i) mechanisms of Li-ion transport through bulk SEI and SEI/electrolyte interfaces, ii) mechanical properties of SEI and its failure mechanism under large deformations, and iii) chemical/mechanical coupling during lithiation of nanostructured Si-based electrodes.

Seminar
The CCER seminars are aimed at researchers interested in computational approaches to (energy) research. The seminar is small-scale, typically 15 participants, and interactive, offering lots of room for discussion.

The Global Energy Transition: the Big Picture
Speaker: Vianney Koelman (CCER)
Time: Sep. 26, 2019, 10:00–11:00
Location: Differ, Alexander-zaal
This interactive presentation gives a high-level overview of the energy transition. Historic global data shed light on key questions: where are we in the transition, why the urgency, what are the prospects, how does fundamental energy research fit into the overall picture?
