In recent years lithium-sulfur batteries have received increasing attention from
various research groups owing to their high theoretical specific energy density. The high
energy storage required by extended range electric vehicles justifies the research effort that
is still necessary to overcome the existing significant obstacles to realize in practice the
theoretical high energy density. 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 electrochemical mechanism occurring in lithium-sulfur batteries, in exploring cathodes,
separators, electrolytes have been reported. Particular emphasis has been devoted to major developments of
novel lithium-sulfur battery configurations by research groups active in the field for decades, proposed in the
logic of system materials engineering.
Keywords: Lithium-sulfur batteries, lithium-free anodes, nanostructured cathodes, polysulfide shuttling,
system materials engineering.
