More impressively, the S/YS-ZnO based Li-S battery can maintain a low decay rate of 0.040% every cycle and high average CE of 98.82% over 1000 cycles at 3 C. Graphical abstract Shuttle effect is still a challenging issue for Li-S batteries. Here, we synthesize the yolk-shell ZnO ...
Shuttle effectThe composite of polythiophene/sulfur/Ketjen black with the layered spherical structure was designed and prepared to reduce the loss of active material and weaken the "shuttle effect" of polysulfides in Li-S battery. Ketjen black particle, which serves as conductive carbon core, was ...
The battery capacity performance which can be hampered due to the shuttle effect and the volume expansion is a serious concern in Li–S batteries and requires a significant alternative strategy for Li-ion batteries. Hence to address these issues, Wang et al. utilized vanadium oxides which can ...
Fluorinated Electrolytes for Li-S Battery: Suppressing the Self-Discharge with an Electrolyte Containing Fluoroether Solvent. J. Electrochem. Soc. 2015, 162 (1), A64-A68.Azimi, N.; Xue, Z.; Rago, N. D.; Takoudis, C.; Gordin, M. L.; Song, J.; Wang, D.; Zhang, Z. Fluorinated...
Keywords: Li-S battery; shuttle effect; MoS2/graphene-coated separator 1. Introduction Lithium-sulfur (Li-S) battery exhibits enormous potential to be the next generation of low-cost and high-capacity batteries due to their high theoretical capacity (1675 mAh g−1), abundance reserves and eco...
However, the polysulfide shuttle effect remains a key obstacle in the practical application of LSBs. Liquid electrolytes, which transport lithium ions between electrodes, play a vital role in battery performances due to the dissolution of polysulfides, and recently, researchers have shown that LSB ...
All the above studies show that an ideal Li-S battery separator should have not only excellent physical properties, but also well-designed macroscopic structure like “double layered structure”, “reticular structure” or “framework structure” to prevent the shuttle effect of LPS. In terms of ...
Shuttle effectPractical application of Li-S battery is limited by the fast capacity decay and low coulombic efficiency caused by the shuttling phenomenon. Modification of the battery separator to impart the separator with ionic sieving property is an effective strategy to alleviate the shuttling ...
Li-S batteryPolar sitesThe lithium sulfur (Li-S) batteries are greatly fascinating as the next-generation storage devices owing to their high theoretical energy density and low cost. However, the fast capacity decay resulting from the "shuttle effect" of polysulfide ions and the irregular ...
