Uses：Tris(trimethylsiloxy) borate is a functional additive, commonly used as a catalyst for polymerization, a neutron absorber, a surface protective agent in arc welding, and used as an intermediate raw material for synthesis of silicon-boron compounds. In recent years, with the vigorous development of new energy vehicles, Tris(trimethylsiloxy) borate is used as the electrolyte additive for lithium ion power battery, which can improve the internal resistance of the battery, so that the battery has better low temperature cycle, high rate normal temperature cycle, high temperature cycle and lower high temperature storage expansion performance.
