固态电解质中间相(SEI)层是锂离子电池(LIB)的关键元素,它能够稳定运行并显着影响包括寿命在内的循环性能。在这里,我们介绍化学软SEI形成添加剂的概念,该概念是通过引入已为人熟知的SEI-former的芳香环基衍生物制成的,以使其具有化学软性,从而生成1,3,2-苯并二氧杂硫醇2,2-二氧化物(DTDPh ),3 H -1,2-苯并硫氧杂2,2-二氧化物(PSPh)和1,4,2-苯并二氧嘧啶2,2-二氧化物(PSOPh)。基于计算DFT的比较可预测有关早期还原过程和受控还原过程的前景。这些预测已通过针对适当的添加剂还原电位的基础电化学研究得到证实,即在任何电解质溶剂或盐分解之前。此外,预测了SEI前体的分解路径,并将最终产品与在LIB单元中形成的SEI层的光谱数据进行了比较。最终形成的SEI层在改善的容量保持性,改善的库仑效率和降低的石墨/电解质/ LFP全电池电阻方面表现出非常好的性
