“…Comparison of the obtained results with the data of [14] indicates that the specific capacity of tin films obtained from pyrophosphate electrolyte is significantly higher compared to the capacity of tin films obtained from citrate-trilonate (750 mA•h•g -1 ), citrate ( 500 mA•h•g -1 ) and tartrate (400 mA•h•g -1 ) electrolytes. Higher specific characteristics of tin precipitation during lithium incorporation and extraction may be due to the difference in the mechanism of their electrolytic production.…”

“…Earlier [14], we published the results of studies of thin tin films obtained from complex tartrate (KNatart), citrate (Na 3 citr), and citrate-trilonate (Na 3 citr/Na 2 H 2 edta) electrolytes as LIB anodes. It has been shown that the nature of the ligand determines such electrochemical characteristics as the specific capacitance value and cycling efficiency.…”

Thin electrolytic fine tin sediments were obtained from pyrophosphate electrolyte under different electrolysis conditions and duration. The electrochemical characteristics of tin coatings as anode materials of lithium-ion batteries are studied using potentiodynamic and galvanostatic cycling methods. The effect of the properties of coatings, in particular their mass, on the value of specific capacitance and its stability, including during discharge with different current densities, has been established. It is shown that the studied tin sediments have high initial specific capacity that is close to theoretically possible. The maximum stability of the specific capacity during cycling is characteristic of electrodes with minimal masses of precipitation. The impedance spectra recorded for the studied electrodes in the initial state and after the first lithiation are analyzed.

“…surface failure and sputtering of the active substance. 2 In a previous work, 3 the electrodeposition and properties of films deposited from tartrate, citrate, and citrate-trilonate electrolytes were investigated; it was shown that the films electrodeposited from a citrate electrolyte had the best charge-discharge characteristics in lithium power sources. The efficiency of citrate solutions was also shown during the electrodeposition of Sn-Cu alloys, which have high corrosion resistance.…”

This paper provides the calculation of the distribution of the concentrations of complex particles of the Sn(II)-citrate-water system in the solution volume, on the surface of the electrode, and in the diffusion layer for the tin citrate electrolyte containing an excess of the ligand. Based on the calculations for the electrodeposition of tin, an electrolyte containing [SnCit] 2− complex at pH 8.0 was chosen. The kinetic parameters of the discharge stage, the diffusion coefficient of the electrochemical active ion, and the current efficiency of tin were determined by the methods of stationary voltammetry and chronovoltamperometry. It is shown that the electroreduction of tin is governed by the laws of mixed kinetics and the transfer stage of the second electron is the limiting one. The discharge mechanism and the composition of the electroactive complex, which is [SnCit] 2− , are proposed. The current density of the deposition of tin coatings with different functional properties is determined as protective coatings and coatings of anodes of Li-ion accumulators.
