A Theoretical Study of Reactions between Polysulfides and Organic Carbonates and Raman Spectra in Lithium-Sulfur Battery [PDF]
, 2015 锂硫电池具有更高能量密度比，近年来锂硫电池研究备受关注。作为电池主要构成的一部分，电解液会显著影响电池的电化学行为。在锂硫电池工作中，如果可溶的多硫阴离子与电解液发生化学反应，将严重影响电池的循环性能。 有机碳酸酯类材料中的碳酸乙烯酯(EC)和碳酸丙烯酯(PC)常作为电解液用于电池。然而，其作为锂离子电池电解液时具有优良的循环性能，但在作为锂硫电池电解液时却使电池循环性能变差。不同的研究者对此现象的认识存在较大的分歧，其主要的分歧在于多硫阴离子(Sn2 ...
