Questions And Answer | Back Directory | [Introduction]
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;
Electrochemical and Physical Properties:
- Viscosity 0.9 cP at 25°C; Conductivity: 1.2 x 10–3 S cm–1 at 25°C (1.0 M LiTFSI); Boiling point 190- 191°C; Glass transition temperature -129°C.
- Soluble electrolytic lithium salt LiTFSI; Less soluble LiBOB.
- Silylated electrolytes show much better electrochemical stability than its carbon and germanium analogues.
- Compares well with other trimethylsilylated polyethyleneoxide oligomers, with longer chain lengths (see also ANL-1NM3; product # 14-1930). Ethylene oxide units in certain electrolytic blends are advantageous improving the conductivity and kinetics of the lithium salts.
