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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
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.

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

open access: yesAdvanced Functional Materials, Volume 36, Issue 62, 3 August 2026.
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.

Impedance of Nonelectroneutral Solid Electrolyte Interphases With Nanopores: A Theoretical Model

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
Physical modeling reveals that often‐neglected non‐electroneutrality and nanopores in the solid‐electrolyte interphase (SEI) govern the impedance behavior. Under nonreactive conditions, the low‐frequency constant‐phase element (CPE) phenomenon can be attributed to the nonelectroneutral local conditions in the SEI.
