Tris(trimethylsilyl) Phosphate (TTSP) Electrolyte Additive
CAS: 10497-05-9
TTSP is a silicon-containing multifunctional electrolyte additive that scavenges trace HF generated from LiPF6 hydrolysis, forms a protective CEI on NMC cathodes, and improves cycle stability at elevated temperatures. Used at 0.5–2 wt%, it is particularly effective in high-voltage (>4.3V) NMC811 and NCA systems.

Vinylene Carbonate (VC) Film-Forming Additive
CAS: 872-36-6
Vinylene carbonate (VC) is the most widely used film-forming electrolyte additive for lithium-ion batteries, polymerizing preferentially on graphite and silicon anodes to build a compact, stable SEI that greatly reduces gas generation and improves cycle performance. Typical addition level is 0.5–3 wt% in the finished electrolyte.
