Abstract
Red phosphorus (RP) is considered a promising anode material for lithium-ion batteries (LIBs) due to its high energy density and low cost. Although RP is electrically insulating, researchers have reduced its particle size and added conductive fillers to improve the electrochemical activity of RP. Here, we report a method for making <1 mu m sized RP under ambient conditions by using tip sonication. A specific surfactant solution was used to stabilize the dispersion of <1 mu m sized RP. Graphene nanoribbons (GNRs) were added to improve the conductivity. The RP-GNR composite achieved nearly maximum capacity at 0.1C and showed a capacity retention of 96% after 216 cycles at 0.4 C in the half-cell. When combined with a LiCoO2 cathode, the full cell delivered a total capacity of 86 mAh/g after 200 cycles at 0.4C. This study has demonstrated the fabrication of high-performance LIBs using RP in a safe, convenient, and cost-effective manner, and the method might be extended for the preparation of other battery or catalyst materials that are difficult to acquire through bottom up or top-down approaches.
