Technical Selection Guide

Why is Tris(trimethylsilyl)borate (TMSB) evaluated as an electrolyte additive?

Tris(trimethylsilyl)borate (TMSB) is a silyl-borate additive used to study moisture/HF scavenging and electrode-interface chemistry. It is commonly placed in multi-additive screening matrices rather than evaluated alone.

Why developers evaluate it

  • Relevant to reactive-species control and borate-containing interphases
  • Supports mechanism-based single-additive and package screening
  • Can be compared through formation, EIS, gas, and retention

Development considerations

  • Confirm storage stability and interactions with other additives
  • Additive interactions may differ from single-component results
  • Benefits must be confirmed at realistic voltage, loading, and temperature

How to compare it

Use a structured matrix with an additive-free baseline, several concentrations, and the intended multi-additive package. Track first-cycle efficiency, impedance, gas or swelling, rate capability, high-temperature storage, and cycle retention rather than judging the additive from one metric.

Technical Profile

Electrolyte Additive Applications

Tris(trimethylsilyl)borate ([(CH3)3SiO]3B) is an electrolyte additive candidate for formulation optimization, interphase control, and performance screening. It can support additive-package development for lithium-ion, sodium-ion, high-voltage, high-rate, or low-temperature electrolyte systems.

  • Electrolyte additive screening and formulation optimization
  • SEI/CEI interphase, gas, impedance, or stability studies
  • High-voltage, fast-charge, or low-temperature electrolyte development
  • Custom additive-package evaluation with salts and solvents
