About this Research Topic
Lithium (Li) metal is widely considered as the ultimate choice of anode materials for the next generation of Li batteries owning to its high specific capacity and very low negative redox potential. Unfortunately, during electrochemical cycling the uneven and uncontrolled Li electrodeposits on Li metal leads to the generation of Li dendrites and other undesired microstructures which has severely hindered its practical application at an industrial scale due to low Coulombic efficiency and associated safety issues. Although several growth models for the development of Li electrodeposits have been proposed and a variety of strategies suggested to mitigate or suppress their nucleation and growth, the fundamental interplay between Li metal, its microstructures, its passive layers, and the overall battery performance remains puzzling.
The goal of this Research Topic is to reveal the underlying correlation between the functioning and failure modes of the Li metal anode and the overall battery electrochemical performances. Specifically, the correlation between the forms (structure, morphology,...) of the plated Li electrodeposits and their unveiled intrinsic electrochemical properties. In addition, the role played by the topological and morphological evolution of Li anode, Li electrodeposits, and passive layers on the battery's cycling stability, rate capability, Coulombic efficiency should be also covered. Exploring this topic would significantly advance the mechanistic understanding between the Li metal anode and battery performance, and thus propel the Li metal anode from laboratory research to practical applications.
Areas to be covered in this Research Topic related to Electrochemical Energy Conversion and Storage may include, but are not limited to:
• Studies of Li metal and Li-alloy based batteries (liquid-, gel-, solid-state)
• In situ/operando characterization of Li microstructures and their electrochemical activity
• Relationship between the morphological and electrochemical properties of the Li anode and the battery performance
• Novel strategies and/or techniques to detect/image/map Li microstructures
• Novel electrochemical characterization algorithms to detect and quantify the generated Li microstructures
• Theoretical modelling of Li electrodeposits (onset and growth) with the battery performance
