Lead-acid battery bipolarity is relative to unipolar. In a conventional lead-acid battery, a grid corresponds to a polar, ie the positive electrode is either a negative electrode, and the bipolarity is used with a substrate, but the two sides of the board are coated with a positive census and negative electrode paste, and a substrate has two Polarity.
For example, the minimum monolate voltage of the unipolar lead-acid battery is 2V, and the bipolar monomer is composed of two unipolar plates by a bipolar substrate. It can be seen that if a 6V battery is made, the single polarity is 3 monomer 6 plates, and the bipolarity requires only one 2 unipolar plates to have a total of 3 pieces.
The bipolar lead-acid battery is significantly advantage that the weight of the grid and the weight of the bus bar, in addition, the inner string of the bipolar monomer, the current path is short, the internal resistance is small. A higher voltage can be provided with a smaller volume, which is better than energy.
The bipolar manufacturing difficulty is on the selection and manufacture of the substrate, that is, how to ensure the light (increased than energy), no porous (inner short circuit), good conductive, corrosion resistance. Second, how to design a more reasonable structure makes it seal, chemically, and there is a good process guarantee on maintenance.
The emergence of bipolar lead-acid batteries greatly compensates for the shortcomings of lead-acid battery quality and slow charging speed, providing a broad development prospect for lead-acid batteries as electric vehicles. The development history of bipolar lead-acid batteries is briefly introduced, and the comparison of the normal battery structure is used to introduce the characteristics of the bipolar lead acid batteries in structure. The base material is the key to the bipolar lead-acid battery technology, which introduces the base material used in the bipolar lead-acid battery. Finally, the main features and advantages of the bipolar lead-acid batteries are briefly introduced, and their prospects are prospected.
