Facet‐Engineered ZnO as an Interfacial Regulator for Stable Lithium Metal Anodes

open access: yesSmall, EarlyView.
Programmable electrothermal‐wave (ETW) processing enables precise facet and morphology control of ZnO, redefining it as an interfacial regulator for stabilizing Li‐metal anodes. ETW‐controlled crystallization modulates diffusion pathways to produce facet‐specific and morphology‐defined ZnO that governs Li nucleation.

A Hybrid Solid‐State Battery with a Panoramic‐Scale Stack of Bulk Electrodes and a Thin‐Film Electrolyte

open access: yesSmall, EarlyView.
A hybrid all‐solid‐state battery (ASSB) is implemented by integrating a thin‐film electrolyte on a bulk anode, and a thick cathode sheet. A densified anode substrate with suppressed porosity is prepared by cold pressing. Thin‐film electrolyte is fabricated onto the bulk substrate via co‐sputtering and infrared‐based rapid annealing.

Plasma Enabled Synthesis of Dual Phase Alkali Metals (Li, Na, K) & Water Co‐Intercalated V2O5 3D TMO Clusters for High Performing Aqueous Zinc Ion Battery

open access: yesSmall, EarlyView.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted considerable attention as a safe and cost‐effective to energy storage system. Cathode materials, which are critical to determining overall AZIB performance, remain a major hurdle to deployment.

Mitigating Mn‐Driven Interfacial Instability in LiMn0.5Fe0.5PO4 Cathodes for Lithium‐Ion Batteries via Surface‐Intensive Ta Doping

open access: yesSmall, EarlyView.
Limited Ta diffusivity during synthesis leads to preferential surface enrichment, resulting in surface‐intensive Ta doping in LMFP. The surface‐localized Ta elongates Li─O bonds and widens Li+ conduction pathways, accelerating charge transport and improving ionic conductivity.
