Abstract
Novel batteries containing single-ion conducting polymer electrolytes (SPEs) are provided. The polymers are polysiloxanes substituted with fluorinated poly(alkylene oxide) side chains having associated ionic species. The polymers have the following structure ##STR1## in which R.sup.1, R.sup.2 and n are as defined herein.
Claims16
A solid-state battery comprising a positive electrode, a negative electrode, and a polymer having the structure ##STR32## wherein:
- R.sup.1 and R.sup.2 are individually selected from the group consisting of moieties having the structure
- --(CH.sub.2).sub.x1 (OCH.sub.2 CH.sub.2).sub.y1 (OCF.sub.2 CF.sub.2).sub.z1 SO.sub.2 R.sup.3
- in which R.sup.3 is --OM, --N(M)SO.sub.2 CF.sub.3 or --C(M)(SO.sub.2 CF.sub.3).sub.2 and M is an alkali metal, or wherein one of R.sup.1 and R.sup.2 has the structure
- --(CH.sub.2).sub.x1 (OCH.sub.2 CH.sub.2).sub.y1 (OCF.sub.2 CF.sub.2).sub.z1 SO.sub.2 R.sup.3
- and the other is selected from the group consisting of hydrogen, lower alkyl, fluorinated lower alkyl, lower alkenyl, fluorinated lower alkenyl, aryl, and aralkylene;
- x1 and z1 may be the same or different and are integers in the range of 1 to 100 inclusive;
- y1 is an integer in the range of 0 to 100 inclusive;
- and
- n is an integer indicating the number of mer units in the polymer.
