The components and structures of the solid-electrolyte interphase (SEI) are critical for stable cycling lithium metal batteries (LMBs). LiF has been widely studied as dominant component SEI, but Li2O, which a much lower diffusion barrier Li+, rarely investigated SEI. effect Li2O-dominated SEI on electrochemical performance still remains elusive. Herein, an ultrastrong coordinated cosolvation diluent, 2,3-difluoroethoxybenzene (DFEB), is designed to modulate solvation structure tailor LMBs....
Micro silicon is considered as the most prospective anode material for large-scale application of lithium-ion batteries (LIBs) due to its low production cost and diverse accessibilities. However, micro anodes coupled with conventional binders generally show poor performances in LIBs. Therefore, developing new high performance LIBs highly desirable. In this work, we report first lignin-derived water-soluble binder (lignin-graft-sodium polyacrylate, PAL–NaPAA) anodes. The PAL–NaPAA obtained...
Polymer/ceramic-based composite solid electrolytes (CSE) are promising candidates for all-solid-state lithium metal batteries (SLBs), benefiting from the combined mechanical robustness of polymeric and high ionic conductivity ceramic electrolytes. However, interfacial instability poorly understood interphases CSE hinder their application in high-voltage SLBs. Herein, a simple but effective that stabilizes SLBs by forming multiple intermolecular coordination interactions between polyester is...
Abstract Gel polymer electrolytes (GPEs) hold great promise for lithium (Li) metal batteries (LMBs). Nevertheless, a critical challenge lies in reducing the thickness of GPEs while maintaining their mechanical integrity to achieve high‐energy‐density LMBs. Additionally, protecting Li anode via electrolyte engineering remains demanding. Herein, an innovative ultrathin (1 µm‐thick) yet robust GPE developed using situ curing technique, featuring nanofibrous, exceptionally strong polyethylene...
