Finite Element Analysis for Li Batteries at the Mesoscale

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Finite element analysis (FEA), through multi‐physics coupling, has been widely employed to calculate mesoscale structures in LIBs that exhibit inherent randomness and disorder (Figure a). It has been extensively applied to the investigation of critical phenomena such as Li dendrite evolution, Li+ concentration gradients, SEI film growth, particle ...

From analytical to data‐driven: multi‐method optimization of a bendable mirror system for dynamic focusing

open access: yesJournal of Synchrotron Radiation, EarlyView.
A small‐radius‐of‐curvature bendable mirror system is developed for dynamic focusing in X‐ray free‐electron laser and synchrotron radiation beamlines, and a transfer‐learning neural‐network and differential‐evolution framework is used for force‐to‐shape modeling and inverse optimization.
