Abstract

The application discloses a use of a two-dimensional MAX phase material, a positive lead paste, a positive electrode and a preparation method thereof, and an electric vehicle. In view of the poor conductivity, low porosity, easy softening and falling-off of a positive electrode of a lead-acid battery, a novel additive, i.e., a two-dimensional MAX phase material, is provided. The two-dimensional MAX phase material is used as an additive in the positive electrode of the lead-acid battery, so that the generation rate of lead dioxide in the formation process is improved, the ohmic resistance of the electrode is reduced, the strength and porosity of the electrode are increased, and the cycle life, rate capability and low-temperature performance of the lead-acid battery are improved.
