The application discloses a high-rate valve-regulated lead-acid battery and a preparation method thereof. The battery comprises a battery shell, a positive plate, a negative plate and an electrolyte arranged in the battery shell. The positive plate and the negative plate are both honeycomb lattice structure plates, and the positive plate is coated with a positive active material, and the negative plate is coated with a negative active material. The components of the positive active material include lead powder, graphite, sulfuric acid, nano lead dioxide and pure water. The components of the negative active material include lead powder, barium sulfate, sodium lignosulfonate, graphene composite additive and carbon black. The discharge rate of the high-rate valve-regulated lead-acid battery can reach 3-5C, and the discharge capacity retention rate is above 95% under the 1C discharge rate, which can meet the demand of 5G base stations, data centers and other fields for instantaneous large current and high power output.

An eye needle rehabilitation needle device, comprising a patch assembly (2) and a needle body (3) limited in the center of the patch assembly (2), the patch assembly (2) comprises an insulating film layer (21), a conductive layer (22) and a glue layer (23) which are superimposed from top to bottom, and the technical key points are that a plurality of piezoelectric components (1) are fixed on the patch assembly (2), the piezoelectric component (1) comprises a plastic shell (14), a conductive diaphragm (13), a strip-shaped piezoelectric energy trapping piece (12) and a mass block (11) arranged at the end of the piezoelectric energy trapping piece (12); a through hole (211) is reserved on the insulating film layer (21), the shell (14) passes through the through hole (211) and is limited between the insulating film layer (21) and the conductive layer (22) through the flange (141) at the bottom, and the conductive diaphragm (13) is adhesively fixed with the conductive layer (22). It has the advantages of simple structure, convenient use, long stimulation time and the like.
