Electrochemical and Physical Properties

1. Disiloxane liquid electrolyte ANL-2SM3 exhibits electrochemical stability, high thermal stability, and low viscosity.- Viscosity 3.8 cP at 25°C; The conductivity and viscosity of ANL-2SM3-based electrolyte are 3.65×10−4 S cm−1 and 18 cP at 25 ?C. Charged cathode material is more thermally stable in the siloxane-based electrolyte than in the carbonate-based electrolyte. Boiling point 269-271°C; Glass transition temperature -103.0°C.
2. Soluble electrolytic lithium salts: LiBOB, LiPF6, ANL-2SM3, and LiTFSIANL-2SM3 is compatible with nanostructured material based electrodes.
3. Disiloxane/LiBOB or Disiloxane /LiPF6 electrolytes show conductivities up to 6.2×10−4 Scm−1 at room temperature. Disiloxane electrolytes doped with 0.8MLiBOB are stable to 4.7 V. The LiBOB/disiloxane combinations were found to be good electrolytes for lithium-ion cells.

Uses

Organosilicon Electrolytes for Lithium Ion Batteries

• Silicon based electrolytes with polyethylene glycol oligomers improve thermal and electrochemical stability of lithium-ion batteries.
• Increases battery long-term stability.
• Are less flammable than conventional organic carbonate-based solvents and maintain the safe operation of batteries.
• Improves conductivity and kinetics of the lithium salts.

Uses

Organosilicon electrolytes offer low flammability and high electrochemical and thermal stability compared to the commonly used carbonate based electrolytes, which renders them suitable for lithium ion battery applications.
