The invention discloses a high-performance solid hydrogen storage material and a hydrogen energy electric bicycle using solid hydrogen as a hydrogen source, and the hydrogen storage material is prepared by the following steps: mixing MgH2 powder, MgF2 powder, LiBH4 powder and a catalyst according to a mass ratio of MgH2: MgF2: LiBH4: catalyst = 45-65: 6-13: 18-30: 5-20, putting the mixture into a ball mill, carrying out ball milling for 4-10 h under the conditions of a ball-to-material ratio of (30-55): 1, argon protection and 300-650 rpm, and carrying out vacuum drying to obtain the high-performance solid hydrogen storage material. The high-performance solid hydrogen storage material is obtained. According to the invention, the MgH2 hydrogen storage alloy and the LiBH4 hydrogen storage alloy are compounded, and MgF2 and the metal oxide-carbon-based material composite catalyst are doped, so that the hydrogen storage capacity of the material can be improved, and the hydrogen desorption reaction temperature can be reduced. The hydrogen energy electric bicycle has the advantages of being safe, efficient, capable of saving energy, environmentally friendly and the like, and has wide application prospects.
