Copper is a common current collector at the anode side in rechargeable batteries. The reactivity of copper is often neglected in battery applications which becomes a problem if the active material is highly reactive as well. Corrosion and compound formation results. Here, we report on the influence of the synthesis method and the role of copper on the electrochemical performance of black phosphorus anodes for sodium ion batteries. Two top-down and one bottom-up approaches were applied to prepare different samples. An easy dip coating process was developed to apply copper prior to usage significantly increasing the capacity of the system.
