The invention discloses a valve-controlled sealed lead-acid storage battery and provides a production process of a novel valve-controlled sealed lead-acid storage battery, which has the advantages of improving hydrogen evolution over-potential of a negative electrode plate, reducing water loss and prolonging service life of the battery, aiming at solving the technical problems in the prior art that antimony in a positive electrode grid is transferred to the surface of a negative electrode grid in a charging process of a pole plate so that the hydrogen evolution potential is reduced and the performance of the battery is reduced and the like. The battery is formed through externalizing a positive electrode plate, assembling the externalized positive electrode plate and an unformed negative electrode plate, and carrying out internalization on the negative electrode plate.
