Description
Technical field
Basis is practical newly belongs to storage battery field, relates to a kind of polar plate of lead acid storage battery.
Technical background
Traditional bipolar lead-acid accumulator generally has the pole plate comprising metallic conduction substrate, apply positive active material and negative electrode active material respectively at the one or both sides of metallic conduction substrate thus form unipolarity pole plate or double polarity plate, by unipolarity pole plate and the stacked formation bipolar battery of double polarity plate.At present, for the pole plate of bipolar battery, the surface of its conductive substrates is general all more smooth, and the active material being coated on its surface easily comes off in the process of discharge and recharge, directly affects life-span and the capacity of battery.
In addition, current polar plate of lead acid storage battery generally directly uses lead or other metals to be main material, and density is large, and specific energy is low, and improving battery specific energy is one of focus of research.
Utility model content
The purpose of this utility model is to provide a kind of polar plate of lead acid storage battery, to solve above-mentioned bipolar storage battery electrode plate Problems existing.
The polar plate of lead acid storage battery that the utility model provides comprises unipolarity pole plate and double polarity plate, the structure of unipolarity pole plate comprises substrate and the first grid, substrate is embedded in the first grid, some through holes are provided with along the direction vertical with substrate in first grid, active material is coated in the through hole of the first grid, and described active material is positive active material or negative electrode active material.Conduct electricity to be connected with outside, the substrate of unipolarity pole plate is also containing lug.
The structure of double polarity plate is increase by the second grid again on the basis of unipolarity pole plate, substrate is embedded between the first grid and the second grid, be equipped with some through holes along the direction vertical with substrate in two pieces of grids, in the through hole of the first grid and the second grid, be coated with opposite polarity active material respectively.
Further, grid is made up of engineering plastics, and the through hole on grid is preferably triangle or cellular.Substrate is made up of material with carbon elements such as graphite, carbon black, bamboo charcoal, carbon fibers.
The polar plate of lead acid storage battery that the utility model provides has following beneficial effect:
1. grid through hole adopts triangle or cellular design, active material difficult drop-off;
2. use carbon moulding material to make, the consumption of 50% lead can be saved, reduce the environmental pollution of production and use procedure, alleviate 30% weight of storage battery, add the specific energy of storage battery;
