About this Research Topic
Lithium metal anodes with their high energy density and low electrochemical potential have been widely considered as promising candidates to overcome the limitations of current anode materials. Nevertheless, for their practical use, there is the need to overcome the main problem of dendrite formation. With the huge increase in energy consumption, it is necessary to start using different sources of energy that need to be stored in batteries. Further, the development of personal electronics and electric vehicles requires energy storage systems with very high energy density. As the mainstream of energy storage systems, lithium batteries play a fundamental role.
The goal of this Research Topic is to present different strategies with the aim to overcome the problems of using lithium metal as an anode in lithium metal batteries. During the repeated charge-discharge cycling in lithium metal batteries, the continuous uneven deposition-stripping of lithium induces uncontrollable growth of lithium dendrites, which not only breaks the solid electrolyte interfacial film and leads to the generation of “dead Li” with low Coulombic efficiency, but also induces safety issues since dendrites can penetrate through the polymer separator and form micro-short circuits between the positive and negative electrodes, that can cause fire and even explosions. Therefore, for the practical use of lithium metal anodes, the severe dendritic lithium formation and mossy metal deposits on the lithium metal surface should be suppressed. In this topic, the aim is to cover the state-of-the-art in the field of lithium metal anode.
Original Research articles and Review articles are welcomed. The scope of this Research Topic includes, but is not limited to, the following topics:
• Lithium metal surface modification
• Electrolyte design
• SEI characterization
• Artificial SEI on lithium metal anodes
• Computational simulations related to lithium metal as anode
