ABSTRACT:

The charge- transfer (CT) complex based on protopine with electron acceptor iodine has been synthesized. The conductivity increases by several orders of magnitude and the activation energy decreases on formation of CT complex. Solidstate battery of configuration Zn protopine- I₂ / graphite has been developed using the CT complex as the cathodic material. The open- circuit voltage af the cell increases with the increase in temperature. The high open- circuit voltage and battery parameters indicate that the CT complex of natural occurring protopine can be used in fabrication of selid- state batteries.
