Trapezoidal balance storage battery

Abstract

The invention relates to a storage battery. A trapezoidal balance storage battery comprises a shell, a positive terminal, a negative terminal, a valve hole, a positive pole plate, negative pole plates, paper blocking plates and bus bars, wherein the positive terminal, the negative terminal and the valve hole are arranged on the shell; the positive pole plate, the negative pole plates, the paper blocking plates and the bus bars are arranged in the shell; the cross section areas of the positive pole plate and the negative pole plates are decreased gradually from top to bottom. The plate widths of the pole plates on the upper part of the storage battery provided by the invention are more than that of the pole pates at the lower part, and the thicknesses of the pole plates on the upper part of the storage battery are more than that of the pole pates at the lower part, so that the utilization ratio of the lower end is just matched with that of the upper end; because the widths of the pole plates at the upper end are increased, the baffles are also increased; because the pole plates at the upper end are thicker, a great amount of electrolyte is required in reaction, and the baffles at the upper end are thicker than that at the lower end; because the volumes of the pole plates at the upper end are large, the generated electricity quantity is great, the baffles at the upper end are thicker, the voltage drop of the positive electrode and the negative electrode can be insulated effectively, and circuit disconnection can be prevented effectively; the balance utilization ratio of the storage battery is improved greatly; the up-down balance property is improved.

Description

technical field [0001] The invention relates to a storage battery, in particular to a trapezoidal balance storage battery. Background technique [0002] The conduction method of the battery on the plate: when charging the battery, the electricity is firstly transferred to the terminal, then transferred to the bus bar by the terminal, then transferred to the upper part of the plate through the bus bar, then transferred to the middle of the plate, and finally passed to the plate The lower part, the closer to the upper part of the polar plate, the greater the power, and it gradually decreases near the middle of the polar plate. The power at the lower part of the polar plate is the smallest, because the power is gradually shared and stored by the polar plate, and the power to the lower plate is the excess power that cannot be stored in the upper part. Therefore, the upper part has been overcharged many times, and the lower part has been undercharged many times. When discharging...

AI Technical Summary

Problems solved by technology

In this way, the upper plate is in the state of overcharge and overdischarge for a long time, and the plate is quickly corroded, softened and invalidated, and can no longer store electricity; while the lower plate is still in good condition, but because the upper end has failed and can no longer conduct electricity, so the lower end The power can not be imported or exported

Therefore, the failure of the battery is the failure of the lower part, which makes the whole battery unusable.

Therefore, the lower part of the battery is not fully functional, and the plate design on the upper part of the battery does not match the power transfer
