Application

Lithium bis(trifluoromethanesulphonyl)imide serves a critical role in enhancing the performance of a variety of electronic systems and devices. This white hygroscopic powder is particularly instrumental in the preparation of chiral imidazolium salt via anion metathesis, and it plays a vital role in the development of rare-earth Lewis acid catalysts. In the realm of energy storage, it is used in both primary and secondary lithium cells utilizing organic liquid and polymer electrolytes, contributing to the efficiency and stability of these systems. Additionally, it is an effective p-dopant for improving the conductivity and hole mobility of Spiro-OMeTAD in perovskite solar cells, paralleling its function in solid-state dye-sensitized solar cells. Known for its hydrophilic nature and high solubility, lithium bis(trifluoromethanesulphonyl)imide coordinates weakly with cations, making it a safer and more effective alternative to lithium hexafluorophosphate, especially in applications requiring robust charge transport mechanisms. Its application was further refined when researchers accelerated the doping process using carbon dioxide and UV light, transforming a previously time-consuming procedure into a rapid one-minute development, significantly benefiting the deployment of perovskite solar cells.
