Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Impact of Discharging Methods on Electrode Integrity in Recycling of Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Electrical and electrochemical discharge methods for end‐of‐life lithium‐ion batteries are compared. Electrochemical discharge better preserves the composition and layered structure of Ni‐rich cathode materials while minimizing residual lithium compounds.

Impact of Extrusion and Direct Calendering on Dry‐Coated Cathodes for Sulfidic All‐Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work demonstrates a parameter optimization for a scalable dry coating process of sulfidic ASSB cathodes (82 wt% CAM, 0.5 wt% PTFE binder) in dry room atmosphere. High‐shear extruder mixing and calendering are used to form a cathode film based on PTFE fibrillation.
