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

In-vitro lithium alloying interface strategy: A hierarchical structure of polymeric macro/mesopores at the lithium interface has sufficient capacity to accommodate and transport lithium ions, thus mitigating pulverization and dendritic growth. This underscores the need for innovative strategies to address irregular lithium nucleation and improve lithium metal battery technology, laying the foundation for more effective anode interfaces in advanced energy applications.

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 the lithium charge behavior. Here, the determination of the appropriate structural conditions and processes to prevent the accumulation of lithium ions on the lithium surface is discussed. Employing a hierarchical structure of polymeric macro/mesopores at the lithium interface, the favorable behavior of lithium ions and the reaction process is monitored. And the way of alloying process is proposed, revealing lithium ion accepted alloyable metals make to lithium-metal intermetallic compounds. The well-distributed alloyable metals in the unidimensional polymeric interface have sufficient capacity to accommodate and transport lithium ions. This emphasizes the need for innovative strategies to address irregular lithium nucleation and enhance lithium metal battery technology.
