摘要
In this work, we investigated the possibility of using a nanoporous Ge layer (p-Ge) formed by implantation with Ag+ ions on a single crystal c-Ge substrate as an anode electrode for a lithium-ion battery. For this, ion implantation of c-Ge plates was carried out at an energy of E = 30 keV, a current density in the ion beam of J=5 μA/cm2, and a dose of D=1.3·1016 ion/cm2. It is shown that the obtained spongy Ag:p-Ge layers, consisting of intertwining Ge nanowires, demonstrate a high Coulomb efficiency (> 97%) after the first cycle and show up to 79.5% of reversible capacity after 1000 cycles.
