Published: Feb. 24, 2023

Abstract The high energy density required for the next generation of lithium batteries will likely be enabled by a shift toward metal anode from conventional intercalation‐based such as graphite. However, several critical challenges Li originate its highly reactive nature and hostless reaction deposition stripping impede practical use an anode. role solid electrolyte interphase (SEI) is very important where SEI must protect dynamically changing surface metal. Since SEI‐generating mechanisms two different systems, liquid solid, are considerably different, layers formed between electrolytes in systems have substantially properties, causing interfacial issues. Inhibition problems requires strategies to reinforce layer each systems. differences not been clearly compared prior literature. In this report, issues modification provided overcome

eTransportation, Journal Year: 2023, Volume and Issue: 18, P. 100272 - 100272

Published: Aug. 21, 2023

All-solid-state batteries (ASSBs) are regarded as the most promising next-generation for electric vehicles in virtue of their potential advantages enhanced safety, high energy density and power capability. Among ASSBs based on various solid electrolytes (SEs), sulfide-based have attracted increasing attention due to ionic conductivity sulfide SEs which is comparable that liquid electrolytes. Extensive efforts from academia industry been made develop ASSBs, several significant progress has achieved recent years. However, successful fabrication high-performance rarely reported, practical application still faces a variety challenges. Herein, following bottom-up approach, we present comprehensive review critical issues material, interface, composite electrode cell levels. The existing challenges, advances, future research directions at multiple levels discussed. Finally, processes scaling up pilot/mass production schedules leading companies also introduced. Facing challenges opportunities, highly encourage joint cooperation across battery community promote ASSBs.

Achieving High‐Power and Dendrite‐Free Lithium Metal Anodes via Interfacial Ion‐Transport‐Rectifying Pump

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(12)

Published: Feb. 2, 2023

Abstract Metallic lithium is a fascinating anode for the next‐generation energy‐dense rechargeable batteries owing to highest theoretical specific capacity and lowest electrochemical potential. Nevertheless, sluggish desolvation kinetics notorious dendritic growth hinder its performance safe operation. Herein, an interlamellar Li + conductor of Ag‐montmorillonite (AMMT) proposed as interfacial ion‐transport‐rectifying pump induce rapid reversible plating/stripping metal. Joint experimental computational analyses reveal that AMMT with negative charge layers inherent channels can lower energy boost transport. The resultant endowed low nucleation barrier (22.2 mV) dendrite‐free features, leading high density (8 mA cm ‐2 ) long lifespan (2500 h). Moreover, corresponding Li||LiFePO 4 achieve steady circulation (500 cycles@82%, 1 C) N/P ratio. This strategy offers fresh insight into constructing robust multifunctional electrolyte/Li interface metal batteries.

The Influences of DMF Content in Composite Polymer Electrolytes on Li⁺‐Conductivity and Interfacial Stability with Li‐Metal

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(25)

Published: March 14, 2023

Abstract Trace N, N‐dimethylformamide(DMF) containing composite polymer electrolytes (CPEs) has attracted much attention owing to the dramatically increased Li + ‐conductivity. But amount of DMF is critical and needs be clarified for interfacial stability, since easily reduced by Li‐metal. Herein, influences in poly(ethylene oxide) (PEO) poly(vinylidene fluoride) (PVDF) based CPEs are studied on ‐conductivity stability. In PEO‐based CPEs, a stronger interaction lithium bis(trifluoromethanesulfon)imide (LiTFSI) with PEO than DMF, can not confined evaporated off. Only ≈0.25wt.% absorbed ceramic electrolyte fillers, giving two times compared DMF‐free counterparts generating stable interface Li‐metal; but over (≥2.2 wt.%) leads serious reactions While PVDF‐based ≈8wt.% LiTFSI PVDF. Short‐term Li‐metal obtained, longer‐term cycling or higher current density gradually aggravated Thanks high‐voltage stability PVDF better performance obtained when they used as catholytes match cathodes.
