  • Analysis of a large dataset of scanning transmission X-ray microscopy images of carbon-coated lithium iron phosphate nanoparticles shows that the heterogeneous reaction kinetics of battery materials can be learned from such videos pixel by pixel.

  • Constitutive laws underlie most physical processes, but understanding chemo-mechanical expansion in heterogeneous solids is challenging. A physically constrained image-learning approach is now proposed to obtain fundamental insight into dislocations inside battery electrodes.

  • Accurately predicting battery lifetime is difficult, and a prediction often cannot be made unless a battery has already degraded significantly. Here the authors report a machine-learning method to predict battery life before the onset of capacity degradation with high accuracy.

  • Phase transformations driven by compositional change require mass flux across a phase boundary. Lithium migration in LiXFePO4 along the solid/liquid interface now suggests that surface diffusion contributes to tuning phase transformation in anisotropic solids.

  • Electrochemical ion insertion is rapidly emerging as a powerful materials design strategy. This Review discusses how ion insertion enables reversible transformation and switching of physico-chemical properties, the role of defects and interfacial reactions, and opportunities for ultrafast ionic control.
