Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Anion Concentration–Regulated Interface Stabilization Enabling High‐Performance Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A higher anion concentration promotes the formation of a LiF‐rich SEI on the Li surface, thereby stabilizing the interface and modifying Li deposition behavior and dendrite morphology, which ultimately determines the cycling performance of Li metal batteries.

Conjugation‐mediated and polarity‐switchable interfacial layers for fast cycling of lithium‐metal batteries

open access: yesInfoMat, EarlyView.
Thiophene‐embedded solid electrolyte interphase exhibits switchable polarity for uniform Li plating, and the electron‐rich cathode electrolyte interphase stabilizes high‐valence Ni ions in the cathode. These molecularly engineered interfacial layers enable fast cycling of lithium‐metal batteries for practical applications.

Chemomechanical Origin of Morphological Disparity in Lithium Metal Electrodeposition

open access: yesAdvanced Materials, Volume 38, Issue 16, 17 March 2026.
Selective dissociation of either solvent or salt on copper current collector induced different solid electrolyte interphase (SEI) layers. The solvent derived organic SEI favors formation of Li whisker, while salt derived SEI favors formation of Li particle, revealing the root cause of Li morphology disparity within the same cell.

Insights on SEI Growth and Properties in Na‐Ion Batteries via Physically Driven Kinetic Monte Carlo Model

open access: yesAdvanced Energy Materials, Volume 16, Issue 12, 25 March 2026.
The novel kinetic Monte Carlo model presented here incorporates spatially‐ and time‐dependent electrical potential, which enables the precise study of the solid electrolyte interphase formation in Na‐ion batteries. The effects of electrolyte composition and charging conditions on the growth and behavior of the solid electrolyte interphase during the ...
