  author={Jie Lin and Howie N. Chu and David A. Howey and Charles W. Monroe},
Untangling the relationship between reactions, mass transfer, and temperature within lithium-ion batteries enables control approaches that mitigate thermal hot spots and slow degradation. Here, we develop an efficient physics-based pouch-cell model to simulate lock-in thermography experiments, which synchronously record the applied current, cell voltage, and surface-temperature distribution. Prior modelling efforts have been confounded by experimental temperature profiles whose characteristics…

Fast lithium growth and short circuit induced by localized-temperature hotspots in lithium batteries
It is discovered that temperature hotspots can induce significant lithium metal growth as compared to the surrounding lower temperature area due to the locally enhanced surface exchange current density.
Multiscale Lithium-Battery Modeling from Materials to Cells.
This review surveys the methods researchers have used to bridge the gap between the nanoscale and the macroscale, and highlights the modeling of properties or phenomena that have direct and considerable impact on battery performance metrics, such as open-circuit voltage and charge/discharge overpotentials.
Operando decoding of chemical and thermal events in commercial Na(Li)-ion cells via optical sensors

Electrochemistry Coupled Mesoscale Complexations in Electrodes Lead to Thermo-Electrochemical Extremes.
It is proposed herein that the electrochemistry-coupled and microstructure-mediated cross talk between the positive and negative electrodes ultimately dictates the off-equilibrium- coupled processes, such as heat generation and the propensity for lithium plating.

3D microstructure design of lithium-ion battery electrodes assisted by X-ray nano-computed tomography and modelling
It is shown that the microstructural heterogeneities lead to non-uniform Li insertion and current distribution while graded-microstructures improve the performance.
