Abstract: In this paper, a kind of bulk submicron red phosphorus/graphite composite (smRP/G) was studied, which was prepared by mechanical ball milling submicron red phosphorus and graphite. Its characteristics were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), cyclic voltammogram (CV) and etc. Compared with common red new energystorage materials, new catalytic materials, submicron red phosphorus is easier to form composites with graphite by ball milling, which can effectively improve the lithium storage capacity of graphite materials. It provides an idea for the application of red phosphorus in the negative electrode materials of lithium-ion batteries. In this work, under the condition of adding a mass percent of 3% red phosphorus, smRP/G shows the best performance. At the current density of 100 mA/g, the first discharge capacity of 1417 mA穐/g is displayed, and the first coulomb efficiency is 67.4%. The reversible capacity of 700 mA穐/g is maintained after 200 cycles.

Key words: red phosphorus, graphite, ball milling, lithium-ion batteries
