Visualizing the Dynamic Wetting and Redistribution of Electrolyte in Lean‐Electrolyte Lithium‐Sulfur Pouch Cells via Operando Neutron Imaging

open access: yesAdvanced Energy Materials, EarlyView.
The inhomogeneous electrolyte wetting in lean‐electrolyte lithium–sulfur pouch cells is visualized by operando neutron tomography non‐destructively. Real‐time observation of electrolyte in different layers of pouch cells reveals different electrolyte wetting behaviors under various cell status, including cell rest, states of discharge, and charge at ...

Bias‐Dependent Quantum Efficiency Reveals Recombination Pathways in Thin Film Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Bias‐dependent external quantum‐efficiency spectra provide three characteristic “fingerprints” that reveal whether charge‐carrier loss in high‐efficiency graded CdSeTe solar cells is dominated by the front interface, the bulk absorber, or the back contact.

Origins of Abrupt Capacity Degradation in Lithium‐Ion Batteries with Silicon‐Based Anodes

open access: yesAdvanced Energy Materials, EarlyView.
A sudden capacity decay in graphite/SiO anodes during long‐term cycling occurs alongside the formation of a “SiO‐SEI crust” near the SiO surface. The self‐accelerating degradation mechanism is revealed: slow lithium diffusion within the SiO particles creates large diffusion‐induced stress from steeper lithium‐ion gradients, resulting in surface ...

Beyond the Artifact: In Situ Quantification of True HER Kinetics During Zn Electrodeposition in Aqueous Zinc Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
For aqueous zinc metal batteries, quantifying the true hydrogen evolution reaction kinetics during Zn electrodeposition requires simultaneous kinetic monitoring of the evolved hydrogen gas. Abstract Aqueous zinc metal batteries (AZMBs) present a safe, low‐cost, and sustainable solution for stationary, grid‐scale energy storage; however, their long‐term
