The advantages of high theoretical
specific capacity, low cost,
and convenient processing of lithium–sulfur batteries (Li–S
batteries) have promoted a new direction for the development of the
battery industry and greatly increased the upper limit of application
of energy storage materials. However, the volume expansion, shuttle
effect, and weak conductivity of sulfur inhibit the development prospect
of Li–S batteries. Herein, the latest research developments
of sulfur composite cathode materials in Li–S batteries are
reviewed, including but not limited to carbon-based materials, metal
and metal compound materials, metal–organic frameworks and
derivatives, and conductive polymers. The electrochemical performance
of Li–S batteries can be greatly improved through modifying
sulfur composite cathodes based on the characteristics of composite
materials and the bottleneck of Li–S batteries. In addition,
the modification and application of the existing anode materials of
Li–S batteries are summarized, which provides the possibility
to promote the further development of Li–S batteries.
Lithium-ion batteries with a stable circulation capacity, high energy density and good safety are widely used in automobiles, mobile phones, manufacturing and other fields.
Room-temperature sodium-sulfur batteries (RT-Na/S batteries) with high reversible capacity (1675 mAh g−1) and excellent energy density (1274 Wh kg−1) based on abundant resources of metal Na have become a research...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
