Potentiodynamic and galvanostatic cycling in 1 M ethylene carbonate-dimethyl carbonate solution of LiClO 4 were used to study electrolytic tin fi lms deposited from complex (tartrate, citrate, and citrate-trilonate) electrolytes. It was shown that the nature of a ligand strongly affects the electrochemical characteristics, specifi c capacity of tin fi lms, and effi ciency of their cycling in lithium power sources. The most stable charge-discharge characteristics are inherent in tin fi lms deposited from the citrate electrolyte.
