Claims18
A solid polymeric electrolyte comprising a organophosphorus polymer having a molecular weight in the range of from about 1,000 to about 80,000 wherein said organophosphorus polymer is selected from the group consisting of polyphosphoro-amides and polyphosphines.
A solid polymeric electrolyte comprising an organophosphorus polymer containing the repeating unit of Formula I:
- ##STR22## wherein k is O or 1;
- Y is selected from the group consisting of --SRS--, --ORS--, --N(R') R N(R')--, and --N(R')R--;
- Z is R' or OR';
- R' is a hydrocarbyl or oxyhydrocarbyl group of from 1 to 40 carbon atoms, and R is hydrocarbylene or oxyhydrocarbylene group of from 1 to 40 carbon atoms;
- and n is an integer having a value between about 10 and 500.
An electrochemical cell having a solid polymeric electrolyte comprising an organophosphorus polymer containing the repeating unit of Formula I:
- ##STR23## wherein k is O or 1;
- Y is selected from the group consisting of --ORO--, --SRS--, --ORS--, --N(R') R N(R')--, and --N(R')R--;
- Z is R' or OR';
- R' is a hydrocarbyl or oxyhydrocarbyl groups of from 1 to 40 carbon atoms, and R is hydrocarbylene or oxyhydrocarbylene group of from 1 to 40 carbon atoms;
- and n is an integer having a value between about 10 and 500.
