Title: Machine learning 3D-resolved prediction of electrolyte infiltration in battery porous electrodes

Abstract

Electrolyte infiltration is one of the critical steps of the manufacturing process of lithium ion batteries (LIB). We present here an innovative machine learning (ML) model, based on the multi-layers perceptron (MLP) approach, to fast and accurately predict electrolyte flow in three dimensions, as well as wetting degree and time for LIB electrodes. The ML model is trained on a database generated using a 3D-resolved physical model based on the Lattice Boltzmann Method (LBM) and a NMC electrode mesostructure obtained by X-ray micro-computer tomography. The trained ML model is able to predict the electrode filling process, with ultralow computational cost and with high accuracy. Also, systematic sensitivity analysis was carried out to unravel the spatial relationship between electrode mesostructure parameters and predicted infiltration process characteristics. This paves the way towards massive computational screening of electrode mesostructures/electrolyte pairs to unravel their impact on the cell wetting and optimize the infiltration conditions.

Insight on electrolyte infiltration of lithium ion battery electrodes by means of a new three-dimensional-resolved lattice Boltzmann model

Journal Article Shodiev, Abbos ; Primo, Emiliano ; Arcelus, Oier ; ... - Energy Storage Materials

Electrolyte filling takes place between sealing and formation in Lithium Ion Battery (LIB) manufacturing process. This step is crucial as it is directly linked to LIB quality and affects the subsequent time consuming electrolyte wetting process. Although having fast, homogeneous and complete wetting is of paramount importance, this process has not been sufficiently examined and fully understood. For instance, experimentally available data is insufficient to fully capture the complex interplay upon filling between electrolyte and air inside the porous electrode. We report here for the first time a 3D-resolved Lattice Boltzmann Method (LBM) model able to simulate electrolyte filling uponmore »« less

Designing electrode architectures to facilitate electrolyte infiltration for lithium-ion batteries

Journal Article Shodiev, Abbos ; Zanotto, Franco M. ; Yu, Jia ; ... - Energy Storage Materials

The electrolyte infiltration is a critical step in the Lithium-ion battery (LIB) cell manufacturing process, impacting for instance the solid electrolyte interphase heterogeneity and the cell ageing. The electrolyte infiltration rate and effectivity are tied to the porous mesostructure and dimensions of the electrodes and the separator, which are mainly dictated by electrochemical performance requirements. We propose here the use of architectures with layers of varying pore network properties as a potential approach to tune the wettability of the cell sandwich. We perform infiltration simulations based on the Lattice Boltzmann Method to analyse the electrolyte saturation as a function ofmore »« less

Deconvoluting the benefits of porosity distribution in layered electrodes on the electrochemical performance of Li-ion batteries

Journal Article Shodiev, Abbos ; Chouchane, Mehdi ; Gaberscek, Miran ; ... - Energy Storage Materials

Thick Lithium Ion Battery (LIB) electrodes suffer from poor rate capability and high ionic impedance due to their thickness and mesostructure. Therefore, optimizing thick electrode architectures becomes crucial. In this work, we report a systematic assessment of the ionic resistance in heterogeneous porous electrodes through the combination of computational simulations using a 4D-resolved model and experimental measurements. The first part of the study is devoted to a general assessment of Electrochemical Impedance Spectroscopy (EIS) spectra, mapping the impact of ionic and electronic resistances on the overall impedances of uncalendered and calendered LiNi_1/3Mn_1/3Co_1/3O₂, LiFePO₄ and graphite electrodes.

A comparative study of machine learning models for predicting the state of reactive mixing

Journal Article Ahmmed, Bulbul ; Mudunuru, Maruti K. ; Karra, Satish ; ... - Journal of Computational Physics

Mixing phenomena are important mechanisms controlling flow, species transport, and reaction processes in fluids and porous media. Accurate predictions of reactive mixing are critical for many Earth and environmental science problems such as contaminant fate and remediation, macroalgae growth, and plankton biomass evolution. Here, to investigate the evolution of mixing dynamics under different scenarios (e.g., anisotropy, fluctuating velocity fields), a finite-element-based numerical model was built to solve the fast, irreversible bimolecular reaction-diffusion equations to simulate a range of reactive-mixing scenarios. A total of 2,315 simulations were performed using different sets of model input parameters comprising various spatial scales of vortexmore »« less

Oriented porous LLZO 3D structures obtained by freeze casting for battery applications

All solid-state lithium batteries are, potentially, higher energy density and safer alternatives to conventional lithium-ion batteries (LIBs). These are particularly attractive characteristics for large-scale applications such as electric vehicles and grid energy storage systems. However, the thin film deposition techniques used to make current devices are not readily scalable, and result in low areal capacities, which translate to low practical energy densities. To overcome these deficiencies, it is necessary to design thicker electrodes similar to what are used in LIBs (30–100 μm), in which the active material is composited with an ionic conductor and an electronically conducting additive, to overcomemore »« less
