Abstract

Results are presented from investigating the effect the parameters of synthesis of Ge–Co–In nanostructures have on their electrochemical properties. It is found that the optimum ratio of aqueous complex solutions of Ge(IV) and Co(II) is GeCo (3 : 2), at which the obtained sample have the highest Coulombic efficiency of 80% at the first cycle equal and reversible capacity with respect to lithium insertion about 1190 mA h/g. Raising the temperature of the solution to 40°C yields samples that have Coulombic efficiencies of approximately 92% without using special organic additives in the electrolyte.
