In‐Vitro Alloyable Unidimensional Polymeric Interface to Mitigate Pulverization and Dendritic Growth for Long Lifespan Lithium Metal Batteries

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 22, 2024

Abstract With its high energy density, lithium metal battery technology encounters empirical challenges such as pulverization and dendrite growth. These can hinder the achievement of long lifespans. To address these challenges, it is important to optimize charge behavior. Here, determination appropriate structural conditions processes prevent accumulation ions on surface discussed. Employing a hierarchical structure polymeric macro/mesopores at interface, favorable behavior reaction process monitored. And way alloying proposed, revealing ion accepted alloyable metals make lithium‐metal intermetallic compounds. The well‐distributed in unidimensional interface have sufficient capacity accommodate transport ions. This emphasizes need for innovative strategies irregular nucleation enhance technology.

Internal Electron‐Donation Allocation Design for Intrinsic Solubilization of Lithium Nitrate in Ester Electrolyte for Stable Lithium Metal Batteries

Angewandte Chemie, Journal Year: 2024, Volume and Issue: 137(1)

Published: Nov. 8, 2024

Abstract Lithium metal batteries (LMBs) have become a hot topic in the research of next‐generation advanced battery technology due to their high specific energy. However, reaction activity between lithium and electrolyte is considered one key bottlenecks limiting large‐scale applications LMBs. As classic additive, nitrate (LiNO 3 ) significantly improves stability ether‐based electrolytes. its solubility carbonate‐based electrolytes widely used lithium‐ion extremely low, causing limited protective capability on metal, which has obstacle commercial application batteries. Here, we enhanced local negative charge density carbonyl oxygen atoms carbonate molecules by introducing electron donors, making it easier for them coordinate with Li + , thereby weakening interaction NO − increasing LiNO ester The modified solvent promotes derivatization decomposition salt anions, leading formation dense SEI layer rich LiF LiN x O y . This ester‐based assembled Li||Li symmetric shows excellent cycling performance over 4000 hours.
