Abstract: | Organosilicon electrolytes exhibit several important properties for use
in lithium carbon monofluoride batteries, including high conductivity/low
viscosity and thermal/electrochemical stability. Conjugation of an anion
binding agent to the siloxane backbone of an organosilicon electrolyte
creates a bi-functional electrolyte. The bi-functionality of the
electrolyte is due to the ability of the conjugated polyethylene oxide
moieties of the siloxane backbone to solvate lithium and thus control the
ionic conductivity within the electrolyte, and the anion binding agent to
bind the fluoride anion and thus facilitate lithium fluoride dissolution
and preserve the porous structure of the carbon monofluoride cathode. The
ability to control both the electrolyte conductivity and the electrode
morphology/properties simultaneously can improve lithium electrolyte
operation. |
