The lithium metal anode in Li–S batteries: challenges and recent progress

Abstract

Critical challenges of Li–S batteries are related with the instability of Li metal during cycling. To overcome these issues, electrolyte modification and artificial SEI layer incorporation-based strategies have been here reviewed.

“Anchor-Turbo” Strategy for Constructing Ni–VO2 Coating Layer to Achieve Wide Temperature and High-Performance Lithium–Sulfur Batteries

“…To further evaluate the advantages of NV-PP, we compared the cycling of two separators at 3 C. As shown in Figure 6b, the Li−S battery with the NV-PP separator still maintained 760 mAh g −1 after 450 cycles under a 3 C rate. The NV-PP separator has a significant capacity increase in the first 50 cycles, attributed to the capacity loss of the first charge and discharge and the collapse of the carbon material structure, 47 and the Coulomb efficiency of NV-PP in 50 cycles of the initial cycle exceeds 100; as a comparison, the PP is only 110 mAh g −1 . Through the test results of variable rate and long cycle, it is easy to conclude that the NV separator has better stability and capacity retention rate.…”

Tendencies in development of energy assistance systems in an electric car

“…They are also significantly lighter. The newest lithiumsulfur (Li-S) battery offered on the market offers an energy density of 2567 Wh/kg, reflecting up to a three to fivefold increase in performance over current Lithium-Ion (Li-Ion) design counterparts [59,60].…”

Advanced cathodic free-standing interlayers for lithium–sulfur batteries: understanding, fabrication, and modification

“…The earliest research concerning LSBs dates from the 1940s. 3 In the 1960s, the concept of S cathode and the prototype of LSBs were both first introduced in succession. 4,5 In 1976, Whittingham et al studied the usage of a lithium metal anode, which was a pioneering job and still provides good reference research even now.…”
