Solid Electrolyte Interphases: Review of Emerging Concepts in SEI Analysis and Artificial SEI Membranes for Lithium, Sodium, and Potassium Metal Battery Anodes (Adv. Energy Mater. 43/2020)

Two friends are skipping stones across a still ocean inlet. The scene represents the joy of collaborating, each rock being one advance, in aggregate making a mountain of new science. The smooth water is the dendrite-free metal anode, the topic of article number 2002297 by Wei Liu, David Mitlin and co-worker. The yellow mountains on the other side are composed of sulfur, the cathode in a metal battery.
