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

Embodiment 1

[0033] Embodiment 1: see Figure 4 and Figure 5 , a four-pole tab plate, including a plate body and tabs, four tabs are fixedly connected to the side walls around the plate body, and the distances between the tabs along the edge of the plate body are equal.

[0034] The pole plates are divided into positive pole plates and negative pole plates.

Embodiment 2

[0035] Example 2: see Figure 6 to Figure 8 , a quadrupole tab group containing the above-mentioned quadrupole tab plate, which is composed of positive and negative plates alternately arranged and stacked in multiple layers, a separator is provided between the positive and negative plates, and the positive and negative plates pass through the positive and negative plates respectively. The bus bars are connected together, the positive and negative bus bars are respectively fixed with positive and negative terminals, the number of the bus bars is eight, and the bus bars form four groups of positive and negative bus bars distributed around the pole group, A set of positive and negative bus bars is distributed on each side wall of the pole group.

Embodiment 3

[0036] Embodiment 3: see Figure 9 to Figure 11 , a quadrupole accumulator containing the pole group of the above structure, including a sealed battery case and an electrolyte, a safety valve is arranged on the upper surface of the battery case, and the electrolyte is filled through the valve hole of the safety valve To the inside of the battery casing, eight terminal holes are opened on the side walls around the battery casing, and the positive and negative terminals are respectively drawn out from the terminal holes to form four groups of positive and negative terminals. On each side wall of the battery casing Set up a group of positive and negative terminals respectively.

[0037] The positions corresponding to the positive and negative terminals on the outer surface of the side wall of the battery case are respectively marked with "+" and "-".

[0038] The battery casing is made of plastic injection molding.

Abstract

The invention discloses a four-pole tab plate, an pole group and a four-pole tab battery. The four-pole tab plate includes a plate body and tabs. Four tabs are fixed on the side walls around the plate body. The distances between the edges of the body are equal; the four-pole ear pole group is composed of positive and negative plates alternately arranged and stacked in multiple layers. There are separators between the positive and negative plates, and the bus bars form four sets of positive and negative bus bars distributed around the pole group. A set of positive and negative busbars is distributed on each side wall of the pole group; a four-pole battery includes a sealed battery case and electrolyte, and eight terminal holes are opened on the side walls around the case. The negative terminals are led out from the terminal holes respectively to form four sets of positive and negative terminals, and one set of positive and negative terminals is respectively arranged on each side wall of the battery case. The invention prolongs the charge-discharge cycle life of the battery, prevents the battery from dehydrating and swelling, and improves the use safety and high-current discharge performance.

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 ...
