Lead-zinc accumulator plate

Abstract

The invention discloses a lead-zinc accumulator plate. The lead-zinc accumulator plate comprises a positive plate and a negative plate, wherein the positive plate and the negative plate are connected by a conducting skeleton; the positive plate is covered by a positive coating; the negative plate is covered by a negative coating; the positive plate and the negative plate are in a grid structure. The lead-zinc accumulator plate has the beneficial effects that the lead-zinc accumulator has good high current discharge stability, strong low temperature start ability, excellent corrosion resistance and long cyclic charge and discharge lives; the plate potential can be stabilized and the influences of other impurities can be reduced during floating charge because zinc is added, thus improving the charge efficiency, increasing the capacity and prolonging the accumulator life; the proportion of calcium is stabilized due to addition of aluminium, so that the grid resistance is reduced, the conductivity is enhanced and the water loss is reduced; the active substance mass is effectively increased and the conductivity and corrosion resistance of the accumulator are enhanced as the noble metal silver is added to the positive and negative plates, so that the use ratio and conversion ratio of the accumulator are fuller, discharge is more thorough, the endurance mileage is more permanent and the service life is longer.

Description

technical field [0001] The invention relates to a battery device, in particular to a pole plate of a lead-zinc storage battery. Background technique [0002] A battery made of lead and acid as a chemical reaction substance is called a lead-acid battery. It is a DC power supply that converts electrical energy into chemical energy when charging, and converts stored chemical energy into electrical energy when discharging. [0003] Lead-acid batteries have a maximum voltage of 2.0V in common system batteries. The second is its low cost, and the third is good high-rate discharge performance, good high and low temperature performance, and can work under the condition of -40-60°C. Easy to use with float charge No "memory" effect etc. Of course, lead-acid batteries also have some insurmountable disadvantages. First, their lifespan is relatively short, and long-term storage in a discharged state will lead to irreversible sulfation of the electrodes. There is a risk of explosion d...
