The resulting composite presents large specific surface area and enhanced conductivity, which can effectively facilitate charge transport and accommodates variations in volume during the lithiation/de-lithiation processes. As a result, the CoP/RGO nanocomposite manifests a high reversible specific capacity of 960 mA·h·g⁻¹ over 200 cycles at a current density of 0.2 A·g⁻¹ (297 mA·h·g⁻¹ over 10,000 cycles at a current density of 20 A·g⁻¹) and excellent rate capability (424 mA·h·g⁻¹ at a current density of 10 A·g⁻¹).en© Tsinghua University Press and Springer-Verlag Berlin Heidelberg 2015cobalt phosphide; nanowires; anodes; lithium-ion batteryJournal article003008074810.1007/s12274-015-0941-52-s2.0-84957034352392866
