Effect of the nature of a ligand on electrochemical characteristic of tin films in cycling in lithium-ion batteries

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