Unipolar horizontal battery and manufacturing method thereof

Abstract

The invention relates to a unipolar horizontal battery which comprises a battery jar, positive and negative polar columns, front and back covers and pole groups connected in series together, wherein a pole group accommodating cavity which is used for accommodating the pole groups is in front-back direction and is opened at front and back parts is formed in the battery jar; positive and negative tabs are respectively arranged the left ends or the right ends of front and back sides of the positive and negative pole plates; cavities for accommodating the positive and negative tabs are formed on the front and back covers; holes through which the positive and negative polar columns penetrate and an injection hole are formed in the front cover, and the front and back covers are hermetically connected with the front and back sides of the battery jar, respectively. A manufacturing method of the unipolar horizontal battery comprises the following steps: 1, manufacturing each part of the battery; 2, filling and coating positive and negative active substances on the positive and negative poles; 3, manufacturing pole groups, welding the positive and negative polar columns, and welding a splice behind the pole groups; 4, putting the pole groups in the battery jar and sealing the back cover; 5, welding a splicer in front of the pole groups and sealing the front cover; and 6, filling an electrolyte.

Description

technical field [0001] The invention belongs to the field of lead-acid storage batteries, and in particular relates to a unipolar battery and a manufacturing method thereof. Background technique [0002] Lead-acid batteries are widely used in many fields because of their low price, simple manufacture, high capacity and stability. The traditional lead-acid battery is a kind of unipolar battery, which is composed of several pole groups arranged in the battery box in series. The positive and negative plates of the pole groups are placed vertically, and the tabs of the positive and negative plates are evenly Placed on the upper part of the corresponding pole plate, the bus bar, positive and negative poles are also tied to the upper part of the battery pole plate. On the whole, because the concentration of the electrolyte in the lower part of the battery is higher than that in the upper part of the traditional lead-acid battery, that is, the electrolyte will be stratified, and t...

Problems solved by technology

In this way, as the number of cycles increases, the imbalance in the working state of the upper and lower parts of the same plate will become more and more obvious, and finally form a vicious circle, resulting in rapid decline in battery capacity and premature termination of life.
