Study of formation features and electrochemical properties of Ge-Co nanocomposite on copper substrate

In this work, we have demonstrated for the first time the possibility of electrochemical formation of Ge-Co nanostructures on a copper substrate, which are globules whose size reaches 1 μm, consisting of smaller particles whose size does not exceed 10 nm. Such nanostructures demonstrate a sufficiently high reversible capacity of about 850 mAh/g and good stability under long-term cycling.
