Abstract

The cover art is based on a reaction scheme indicated in the article entitled “Moisture Exposure as Pretreatment of Sulfide Solid Electrolytes for All-Solid-State Batteries” by Dr. Hikaru Sano et al., which was selected as Editor’s Choice. The paper reports that only the surface of the sulfide solid electrolyte is degraded by exposure to moisture at a dew point equivalent to that of a typical drying chamber for lithium-ion battery production, and that the surface degraded material includes lithium carbonate and other lithium salts, which act as modified surface layer of the cathode active material. The results of the formation of lithium carbonate by the reaction of a carbon-free solid electrolyte with carbon-free water are interesting.
