Carbon-coated Zn₂GeO₄ on Ni foam as lithium ion battery anodes with exceptional long cycling stability

In this work we have investigated lithium ion battery anodes based on Zn₂GeO₄, which were directly synthesized on 3D Ni foam substrates and were in situ coated with a conductive carbon layer. The hybrid electrodes exhibited outstanding electrochemical performance, including an exceptional long-term cycling stability with reversible discharge capacity of over 1100 mAh g⁻¹ obtained after being tested for 1000 cycles at 400 mA g⁻¹. This study of hybrid electrodes may present an interesting approach to creating efficient and practical electrodes for energy storage applications
