| Questions And Answer | Back Directory | [Electrochemical and Physical Properties]
- 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.
- Soluble electrolytic lithium salts: LiBOB, LiPF6, ANL-2SM3, and LiTFSIANL-2SM3 is compatible with nanostructured material based electrodes.
- 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.
