Positive electrode lead paste formula for prolonging cycle life of lead-acid battery and improving low-temperature performance of lead-acid battery and preparation method of positive electrode lead paste formula

The invention discloses a positive lead paste formula for prolonging the cycle life and improving the low-temperature performance of a lead-acid battery, and belongs to the technical field of storage battery production. The formula of the positive lead paste comprises lead powder, conductive ground carbon fiber powder, 4BS seed crystal, red lead, super-strong polyester staple fibers, bamboo-like carbon nanotubes, SnSO4, Sb2O3, Bi2O3, a CMC + SBR mixed solution, super-strong polyester staple fibers, bamboo-like carbon nanotubes, red lead, dilute sulphuric acid and deionized water. A mixed solution of CMC and SBR is used as a binder, so that the condition that the positive lead paste falls off in the use process can be improved; the conductive ground carbon fiber powder is added, the bamboo-like carbon nanotubes can replace short fibers and graphite, the deformation problem influenced by large volume change generated in the charging and discharging process of a PbO2 electrode can be relieved, and the high-curre
