Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Li‐Ion Battery Anodes Combining Intercalation and Plating Energy Storage Mechanisms through SiOx/C Coated Graphite

open access: yesAdvanced Functional Materials, EarlyView.
A thin SiOx/C coating enables graphite to stably support Li intercalation and Li plating in a hybrid anode. Paired with an optimized localized high‐concentration electrolyte, the full cell achieves 584 mAh g−1 and 86% capacity retention after 500 cycles, highlighting a practical route toward higher‐energy lithium‐ion batteries.

The Influence of Mesoscale Particle Structure on the Electrode Degradation and Resultant Electrochemistry of Lithium Ion Cells With Nickel Rich Lithium Nickel Manganese Cobalt Oxide Positive Electrodes

open access: yesAdvanced Materials Technologies, EarlyView.
Milled polycrystalline NMC811 cathode (MPC NMC) with smaller secondary particle and higher surface area had 1) greater cathode tortuosity, 2) reduced surface Ni on the cycled MPC cathodes consistent with surface reconstruction, and 3) increased Ni deposition from cathode‐anode crosstalk, manifesting in lower functional capacity and higher impedance ...
