This work presents the results of investigation of the influence of synthesis parameters of Ge-Co-In nanostructures on their electrochemical properties. It was found that the optimal ratio of aqueous complex solutions of Ge (IV) and Co (II) is GeCo (3:2), at which the obtained sample has the highest Coulombic efficiency at the first cycle equal to 80% and reversible capacity with respect to lithium introduction about 1190 mAh/g. In turn, increasing the solution temperature to 40°C allows to obtain a sample which has a Coulombic efficiency at the first cycle of about 92% without the use of special organic additives in the electrolyte.
