About this Research Topic
The rapid development of personal electronics and electric vehicles encourages researchers to explore energy storage devices with higher energy densities. Lithium metal, which is the earliest anode of lithium batteries, developed in the 1970s is on the way of reviving due to its extremely high theoretical specific capacity and the lowest negative electrochemical potential. While there have been significant progresses, the challenges for fully utilizing lithium metal as an anode in commercial cells are still immense. For example, Li anode forms dendritic and mossy metal deposits, which induces a severe safety risk, low efficiency, and hinders the practical demonstration of high-energy-density Li metal batteries.
As the electrochemical reaction of lithium metal proceeds at solid-liquid interface, the crucial point to solve problems in lithium metal is how to build up a perfect solid-liquid interface to promote the interfacial electrochemistry. Although lots of efforts have been placed on structural engineering of lithium metal, the intrinsic electrochemistry needs to be revealed. In this topic, we aim to collect many contributions covering all aspects of the interfacial electrochemistry of lithium metal, ranging from the interfacial and structural engineering of lithium metal, starting from practical battery applications, as well as the detailed electrochemical investigation of modified lithium metals.
Areas to be covered in this Research Topic may include, but are not limited to:
• New strategies on lithium metal modifications and protection;
• Interfacial electrochemistry between lithium metal and electrolyte (Experimental and theoretical);
• In-situ characterization of lithium metal anode;
• Practical applications of lithium metals in coin cells/pouch cells
