Technical Field
The invention relates to the technical field of lithium batteries, in particular to a lithium battery busbar.
Background
With the development of battery technology, particularly lithium ion batteries, soft-package lithium batteries are widely used. In order to increase the capacity and the voltage, a method of connecting the unit soft package lithium batteries in parallel and then in series is often adopted at present. The company has applied for a soft package lithium battery series-parallel integrated bus bar, which comprises more than 1 middle bus bar and 2 output bus bars; the middle bus bar comprises a middle bus bar body and more than 2 first electrode connecting supports; the middle bus bar body is a strip-shaped thin plate component and is horizontally arranged; the middle bus bar body is fixedly connected with a first electrode connecting support at intervals on the upper end surface along the length direction; the first electrode connecting support comprises a first connecting plate vertically arranged on the upper end face of the middle bus bar body; a first slot is arranged on the middle bus bar body and close to the first electrode connecting support and the first connecting plate. When the lithium battery busbar is used, the electrode is inserted into the first slotted hole and fixedly connected to the first connecting plate. The lighter the lithium battery is, the better the lithium battery is, so the current lithium battery bus bar has the following main defects: firstly, the first slotted hole is required to be processed on the row body, the manufacturing process is complex, and the manufacturing cost is high; and secondly, after the first slotted hole is processed on the busbar body, in order to ensure the through-flow effect, the width of the middle busbar body needs to be increased, so that the quality of the lithium battery busbar is heavier, and the requirement of light weight of the existing lithium battery cannot be met.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the soft package lithium battery busbar which simplifies the manufacturing process and obviously reduces the quality.
The invention achieves the technical aim through the following technical scheme.
The soft package lithium battery busbar comprises a busbar body and more than 2 electrode connecting supports; the row body is a strip-shaped thin plate component; the electrode connecting support is composed of a row body connecting plate and an electrode connecting plate which are formed by bending a thin plate at right angles; the electrode connecting supports are arranged on the end face of the row body at intervals along the length direction of the row body, the outer end face of the row body connecting plate is fixedly connected to the end face of the row body, and the electrode connecting plate is perpendicular to the length direction of the row body and vertically arranged on the end face of the row body; the improvement is that: one side of the electrode connecting plate extends out of the side edge of the row body connecting plate in the direction vertical to the length direction of the row body and extends out of the side edge of the row body; the electrode to be connected is fixedly connected to the end face of the electrode connecting plate extending out of the side edge part of the row body.
Further, after the electrode to be connected is fixedly connected to the end face of the electrode connecting plate extending out of the side edge portion of the row body, the electrode connecting plate is pulled flat to enable the outer end face of the electrode connecting plate to be attached to the end face of the row body fixedly connected with the row body connecting plate, or the electrode connecting plate is bent to enable the inner end face of the electrode connecting plate to be attached to the inner end face of the electrode connecting plate.
Compared with the prior art, the invention has the following positive effects:
1. one side of the electrode connecting plate extends out of the side edge of the row body connecting plate in the direction vertical to the length direction of the row body and extends out of the side edge of the row body; the electrode to be connected is fixedly connected to the end face of the electrode connecting plate extending out of the side edge part of the row body. Therefore, the through-flow requirement can be met only by the narrow row body without grooving on the row body, so that the manufacturing process is obviously simplified, and the quality is obviously reduced.
2. After the electrodes to be connected are fixedly connected to the end faces of the electrode connecting plates extending out of the side edge portions of the row body, the electrode connecting plates are pulled flat to enable the outer end faces of the electrode connecting plates to be attached to the end faces of the row body fixedly connected with the row body connecting plates, or the electrode connecting plates are bent to enable the inner end faces of the electrode connecting plates to be attached to the inner end faces of the electrode connecting plates. Thus, the space is saved, and the product structure is compact.
