Pseudosolvent Guiding Ultralight V₂CT_x/Bacterial Cellulose with Fast Ion Diffusion Paths for High‐Rate and High‐Capacity Lithium Metal Anodes

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

Abstract Practical application of Li metal anodes (LMAs) is restricted by growth dendrites. Achieving uniform deposition with high practically available specific capacity vital to obtain advanced LMAs. Herein, an ultralight V 2 CT x /bacterial cellulose (U‐V /BC) foam a volume density 0.039 g cm −3 guided tertiary butanol avoid restacking both and BC. The lithiophilic functional groups BC synergistically induce the nucleation. loose stacking structure U‐V /BC provides 3D ion channels for accelerating + diffusion, homogeneous flux, as well enough sites interspace deposition. As result, /BC@Li exhibits superior stability 2800 h at 5 mAh −2 mA ultrahigh 2040 −1 . Furthermore, full‐cells paired LiFePO 4 cathodes possess remarkable retention 80.7% after 800 cycles 1 C. Even harsh conditions, /BC@Li||LiFePO can also run 100 0.3 C 84.9%. This work sheds light on surface engineering multiscale architecture design LMAs capacity.

Published: Feb. 10, 2025

Despite the great potential of Li-metal anodes, high reactivity Li metal and dendritic growth hinder stable operation batteries. Artificial protective layers have been introduced as a solution to stabilize interface between electrolyte anode. In this study, we propose functionally designed polymeric ionic liquid (PIL) for interfacial stabilization anodes in quasi-solid-state Polycationic PILs are form conductive robust interphases at PIL/Li while serving an effective electrostatic shield suppress dendrite growth. addition optimized composition facile Li+ transport kinetics PIL, anion configurations PIL engineered produce highly ionic-conductive Li3N increase concentration LiF solid–electrolyte interphase.

Erecting Stable Lithium Metal Batteries: Comprehensive Review and Future Prospects

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 3, 2025

Abstract As the global energy structure transforms and renewable rapidly develops, rechargeable batteries are increasingly focus on high density, rapid charge/discharge rates, enhanced safety performance, particularly in extreme environments. Lithium metal (LMBs) have emerged as a significant research area recent years owing to capacity low electrochemical potential of lithium (Li). However, challenges, uncontrolled Li dendrite growth, unstable solid electrolyte interface separator puncture/interface incompatibility, greatly impact battery life lead failure, thus impeding commercialization. This review presents thorough analysis key challenges facing stable LMBs from multiple perspectives, alongside regulatory strategies. The methods include anode, interface, solid/liquid electrolytes, separators, pressure artificial intelligence. An in‐depth discussion operational mechanism, advantages/drawbacks is provided. Additionally, it offers succinct overview anticipated future trends challenges. A comprehensive numerous documents studies has been conducted summarize number published papers unique characteristics corresponding provides valuable recommendations for practical application other high‐energy‐density (Sodium, Potassium, Magnesium, Zinc), thereby contributing effectively implementation national strategic planning new sector.
