Studies of the Fundamentals of Solid-State Batteries.
Abstract
Studies of lithium/Titanium Sulfide cells utilizing polybis(methoxyethoxyethoxide) phosphazene) (MEEP) based polymer electrolytes have demonstrated the excellent potential of this inorganic polymer electrolyte for use in solid-state rechargeable Li batteries of applications at or near room temperature. A major drawback of the MEEP electrolyte has been its lack of dimensional stability, manifested in its tendency to flow. This flow property prevented the preparation of thin film solid electrolytes. A solution to this problem has been found in this program by blending MEEP with poly(ethylene oxide), PEO, which resulted in novel mixed polymer electrolytes exhibiting superior mechanical stability and high conductivity. We have also developed a technique to fabricate solid-state cells with the pure MEEP electrolyte by supporting it on a thin, porous matrix comprising a fiberglass separator.
