is limited in part by the dissolution of lithium-polysulfide in the electrolyte. Remarkably, it is found that removal of the conventional membrane separator in a Li-S cell improves sulfur utilization and cycling performance, whether the sulfur is initially contained in the cathode or electrolyte. An optimized cell design yields discharge capacities as high as 980 mA h g after 100 cycles.
部分受限于锂多硫化物在电解质中的溶解。值得注意的是，研究发现，在锂硫电池中去除传统的隔膜会提高硫的利用率和循环性能，无论硫最初是包含在阴极还是电解质中。经过优化的电池设计在100次循环后可产生高达980 mA h g的放电容量。
