Large-volume-expansion-induced material pulverization severely limits the electrochemical performance of red phosphorous (P) for energy-storage applications. Hollow nanospheres with porous shells are recognized as an ideal structure to resolve these issues. However, a chemical synthetic approach preparing nanostructured P is always great challenge and hollow nanosphere structures have not yet been fabricated. Herein, wet solvothermal method successfully fabricate (HPNs) via gas-bubble-directed formation mechanism developed. More importantly, due merits structures, HPNs reveal highest capacities (based on weight electrode materials) 1285.7 mA h g-1 lithium-ion batteries 1364.7 sodium-ion at 0.2 C, excellent long-cycling performance.
