That could boost the capacity of lithium-ion batteries to 500 Wh/kg—enough to drive a car nearly 500 kilometers between charges—and yield even bigger gains for lithium-sulfur batteries. To date, however, pure lithium anodes have been stymied by problems during charging, when lithium atoms migrate back from the cathode.
Lithium–sulfur batteries (LSBs) (wherein lithium metal and sulfur are the anode and cathode, respectively) are one of the most valuable secondary batteries because of their high theoretical energy density (∼2600 Wh kg −1). However, the intrinsic conductivity of sulfur cathode materials is poor, and the lithium polysulfide formed during …
Lithium-sulfur (Li–S) batteries are among the most promising next-generation energy storage technologies due to their ability to provide up to three times greater energy density than conventional lithium-ion batteries.
