A new synergistic lithium ion solvation structure effect tailored by mixed organic/inorganic lithium salts is introduced to mitigate the growth of lithium-dendrites. A uniform lithium plating, lower polarization and higher coulombic efficiency are confirmed by lithium plating/stripping. The effect of different solvation structures was analyzed by Raman spectroscopy and simulations. Then, a reliable lithium-sulfur full battery with high performance over hundreds of cycles was configured.
引入了一种由有机/无机锂盐混合物定制的新型协同锂离子溶剂化结构效应，以减轻锂枝晶的生长。通过锂电镀/剥离证实了均匀的锂镀层、较低的极化和较高的库仑效率。通过拉曼光谱和模拟分析了不同溶剂化结构的影响。然后，构建了一种可靠的高性能锂硫全电池，可在数百次循环中保持良好性能。
