• Application: Tris(Trimethylsiloxy)Boron serves as a versatile component in both organic synthesis and lithium battery technology. Its application as an additive in lithium battery electrolytes enhances the longevity and efficiency of high-voltage cathode materials such as LiMn2O4, LiNi0.5Co0.2Mn0.3O2, LiNi0.5Mn1.5O4, and lithium-rich oxides. This additive is particularly useful in improving cycle performance by forming a protective, thin, and dense cathode electrolyte interphase (CEI) film enriched with silicon and boron compounds. This film effectively reduces interfacial resistance growth during battery cycling. Moreover, Tris(Trimethylsiloxy)Boron alters the solvation structure of lithium ions, facilitating their mobility and interaction with the electrolyte, which is crucial for maintaining battery performance at elevated temperatures.
