Opis

Opis ogólny

Tris(trimethylsilyl) borate (TMSB) is an electron-deficient organoborate compound. It is a colorless liquid that that is miscible with many organic solvents, including the linear and cyclic carbonates used in battery applications. Our battery grade TMSB is differentiated by its high purity and low trace water content to ensure consistent and reliable performance in batteries.

Zastosowanie

Tris(trimethylsilyl) borate has a wide range of applications in various industries, including battery manufacturing, where it is used as an electrolyte additive, particularly in high-voltage lithium-ion batteries. TMSB is a cathode-film-forming additive that forms a thin protective coating called a solid-electrolyte interface (SEI) on the surface of the cathode. Adding TMSB to the electrolyte formulation, even at low concentrations of 0.5 wt.%, noticeably improves capacity retention for NMC, LMO, and LMNO cathodes. TMSB also is shown to reduce the flammability of the electrolyte and improve the thermal stability of LiPF₆-based electrolytes at elevated temperatures.
TMSB also has catalytic properties, which make it useful in organic synthesis reactions and as a reagent in the manufacturing of pharmaceuticals and other chemicals.
