| Organosilicon Electrolytes for L ithium lon Batteries 1. Silicon based electrolytes with polyethylene glycol oligomers improve thermal and electrochemical stability of lithium-ion batteries . Increases battery long-term stability. 3.Are less flammable than conventional organic carbonate-based solvents and maintain the safe operation of batteries. 4. Improves conductivity and kinetics of the lithium salts; Electrochemical and Physical Properties: 1. Viscosity 1.4 cP at 25'C, doped with 0.8M LiBOB electrolyte 1.9 cP at 25"C; Conductivity of 0.8M L iBOB doped electrolyte: 1.18 x 10-3 s cm1 at 25'C; Thermally stable up to 400'C. Boiling point 233-234C; Glass transition temperature -1 16'C [1, 2]. 2. Soluble electrolytic lithium salts: L iBOB, L iPF6 (o3 -0325), L iBF4 (o3 -0325 Strem product - not battery grade) and L iTFSI 3. ANL -1 NM3 electrolytes show ex cellent charge/discharge cycling behavior in lithium-ion cells . Silane-based electrolytes with certain lithium salts are stable to 4.4 V [1] Compared to other trimethylsilylated polyethyleneoxide oligomers (see also ANL - 1NM2; product # 14-1925) with two and three ethylene oxide units, these electrolytic blends are adv antageous for the conductivity and kinetics of the lithium salts [2]. some cases, ANL-1NM3 is more preferable because of the higher boiling point (233-234'C vS 190-191'C of ANL -1 NM2)and a lower viscosity. ANL- 1NM3 doped with lithium salts exhibit high ionic conductivity (more than 10 3 s cm 1) at room temperature. L ithium bis(oxalate )borate (LiBOB) a salt blended silicon electrolyte shows the most stable and highest electrochemical performance [3-5]. In addition, silylated electrolytes show much better electrochemical stability than carbon and germanium analogues [6]. 6. Organosilicon electrolytes help to enhance the transport properties of other electrolytes [7], show excellent thermal and electrochemical stability [8] and are applicable for L i-air batteries [9] References: 1.
