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.

Electrolytic deposits of tin-nickel alloys as anodes for lithium ion batteries were investigated by potentiodynamic and galvanostatic cycling methods in solutions of ethylene carbonate, dimethyl carbonate, and LiClO 4 (1 mol/L). It has been shown that the deposits of tin-nickel alloys obtained from alkaline tar trate-trilonate electrolytes in the first cycles are characterized by a high specific capacity of up to 700 mA h/g, which decreases to 500 mA h/g during the cycling. The tin-nickel alloys obtained are able to ensure high charge-discharge current densities without mechanical destruction.
