Lithium metal anodes are crucial in moving toward high-energy-density lithium batteries for a variety of applications, but they suffer from an assortment of safety issues and poor long-term cycling performance. The easiest way to address this is to modify the currently used electrolytes in order to improve the performance in the cell. Carbonate-based electrolytes are one of the few types of solvents that not only participate in solid electrolyte interphase (SEI) formation but also are stable up to high potentials, making them ideal for applications with high-voltage cathodes and lithium metal anodes. While current standard carbonate electrolytes have poor performance, modifying the electrolyte by adjusting the salt or including electrolyte additives can lead to significant improvements in SEI generation and lithium metal battery longevity.

锂金属电极碳酸盐电解质的改性
锂金属阳极对于各种应用的高能量密度锂电池的发展至关重要，但它们存在各种安全问题和较差的长期循环性能。解决这个问题的最简单方法是修改当前使用的电解质，以提高电池的性能。碳酸酯电解质是少数几种不仅参与固体电解质界面（SEI）形成而且在高电势下保持稳定的溶剂之一，使其成为高压阴极和锂金属阳极应用的理想选择。虽然当前标准碳酸盐电解质的性能较差，但通过调整盐或添加电解质添加剂来改性电解质可以显着提高 SEI 生成和锂金属电池寿命。
