Four-pole-ear pole plate, four-pole-ear pole group and four-pole-ear storage battery

Abstract

The invention discloses a four-pole-ear pole plate, a four-pole-ear pole group and a four-pole-ear storage battery. The four-pole-ear pole plate comprises a plate body and pole ears, wherein four pole ears are fixed on the peripheral side walls of the plate body; the distances among the pole ears along the edge of the plate body are equal. The four-pole-ear pole group is composed of multiple layers of positive pole plates and negative pole plates in an alternative arrangement and lamination mode, wherein baffles are arranged between the positive pole plates and the negative pole plates; bus bars form four groups of positive and negative bus bars which are distributed at the periphery of the pole group; a group of positive and negative bus bars are distributed on each side wall of the pole group. The four-pole-ear storage battery comprises a sealed battery outer shell and electrolyte, wherein eight terminal holes are formed on the peripheral side walls of the outer shell; positive and negative terminals are respectively led from the terminal holes so as to form four groups of positive and negative terminals; each side wall of the peripheral walls of the outer shell is respectively provided with a group of positive and negative terminals. According to the invention, the battery charging and discharging cycle life is prolonged; the battery is prevented from expanding because of water loss; the using safety and high-current discharge performance are improved.

Description

technical field [0001] The invention relates to a four-pole tab plate, an pole group and a four-pole tab storage battery, belonging to the field of lead-acid storage batteries. Background technique [0002] At present, the commonly used lead-acid battery is a unipolar battery. The appearance of the battery has a positive pole and a negative pole. The internal connection is a positive terminal and a negative terminal, which are respectively connected to the positive bus bar and the negative bus bar, and then respectively connected to the positive pole. plate and negative plate, the plate structure has only one tab, and the current dispersion and collection of the entire plate is through the pole import and export (see Figure 1 to Figure 3 ). The prior art monopolar battery has the following disadvantages: 1. Due to the ohmic resistance characteristic of the distance, the resistance close to the plate lug is small, and the shared current is large, and the resistance far away ...

Problems solved by technology

The prior art monopolar battery has the following disadvantages: 1. Due to the ohmic resistance characteristic of the distance, the resistance close to the plate lug is small, and the shared current is large, and the resistance far away from the plate lug is large, and the shared current is small. The charging and over-discharging of the active material near the ear exist for a long time, so the active material is easy to loosen and soften, and even the internal lead bars are corroded and broken; the active material far away from the ear is undercharged for a long time, and the discharge is not effective, so the active material is easy to form More lead sulfate, final vulcanization, poor electrical conductivity of living things, even failure; 2, because the safety valve valve hole of prior art monopolar battery is arranged on the side of battery case, battery must be placed upright, and the acid density of the upper part of the battery is low, and the lower part Phenomena such as high acid density lead to inconsistent reactions between internal acid and lead living matter, leading to battery failure, and because the battery is kept upright, it will cause the accumulation of upper and lower temperatures of the battery, resulting in heat overlapping effects, resulting in dehydration and swelling
