In this review, after a brief overview of the current context and scientific/technical challenges for the development of lithium-sulfur batteries, some advances in the knowledge of electrochemicalmechanism occurring in lithium-sulfur batteries, in exploring cathodes, separators, electrolytes have been ...
Lithium sulfide is a promising cathode material for high-energy lithium ion batteries because, unlike elemental sulfur, it obviates the need for metallic lithium anodes. Like elemental sulfur, however, a successful lithium sulfide cathode requires an inherent mechanism for preventing lithium polysulfide ...
