Dynamic Integrated Interface for Synergistic Li + Redox‐Diffusion in Low‐Temperature Lithium Metal Batteries

Hongyang Li, Yue Wang, Jingang Zheng, Hao Huang et autres

ABSTRACT Practical application of lithium metal batteries (LMBs) is severely hindered by nonuniform lithium (Li) nucleation during the charging process. Low‐temperature conditions further substantially elevate the barrier for Li + reduction, leading to uncontrolled dendritic growth. Herein, we propose a “synergistic Li …

Electrophilic Effect of Polysulfide Cations Induces the Formation of Li+-Transport-Enhanced Polymer Electrolyte

Hongxu Zhou, Xiao‐Ning Wang, Yiyang Zhao, Jingang Zheng et autres

Slow ion transport kinetics hinder the development of solid polymer electrolytes in lithium metal batteries. Herein, we adopt the electron-deficient Li 3 S 6 + as an electrophilic initiator to induce the ring-opening copolymerization of 1,3-dioxolane and ethylene glycol diglycidyl ether in …

Combined Effect of Fluoride Enables the Stable Charging–Discharging Cycle of Carbonate-Based Li-Ion Pouch Cells at −30 °C

Hao Huang, Yiyang Zhao, Jingang Zheng, Weichen Han et autres

Carbonate-based electrolytes in Li-ion batteries are limited by low-temperature performance due to their slow ion transport kinetics and high interfacial transport energy barriers. Herein, we propose a component modulation strategy from the combined effect of fluor-solvents and fluor-additives, where the noncoordinated 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether …

Architecting Host–Guest Synergistic Solid-State Electrolytes Enables Unobstructed Li-Ion Interphase Migration for Lithium Metal Batteries

Jingang Zheng, Hao Huang, Hongxu Zhou, Hongwei Zhao et autres

Composite solid-state electrolytes inherit the intrinsic merits of each polymer and the inorganic solid-state electrolyte. However, their combined products are still unsatisfactory due to the unmatched Li-ion transport properties and the absence of structural integrity. Herein, an architectural inorganic–organic solid-state electrolyte (AIOSE) …

Elucidation of Li+ Conduction Behavior in MOF Glass Electrolyte Toward Long‐Cycling and High C‐Rate Lithium Metal Batteries

Ourui Kong, Guangshen Jiang, Kun Wang, Anping Yang et autres

Abstract Vitrified metal–organic frameworks (MOFs) are promising solid‐state electrolytes for lithium metal batteries due to their unique structures. Nevertheless, the effect of distorted molecular structures in glassy MOFs on Li+ migration behavior at the molecular level remains largely unexplored, posing a huge …
