Abstract
Conjugated backbone polymers (e.g., polyacetylene), especially formed into a battery electrode, are contacted with a compound MR where M is an alkali metal and R is alkyl of 1-12 carbons, phenyl or alkylphenyl of 7-12 carbons. The method is particularly suited to treatment of battery electrodes to avoid a high initial internal resistance.
