Dimercaptan-Polyaniline Cathodes for Lithium Batteries. Addition of a PolypyrroleDerivative for Rapid Charging

摘要

A polymer composite cathode prepared from polyaniline and 2,5-dimercapto-1, 3,4-thiadiazole shows high gravimetric energy density when it is coupled with a lithium anode. However, charging and discharging currents should be 0.05 mA/sq cm or less, otherwise the cycle life is shortened. Addition of a polypyrrole
