Horizontal Conductive Connection Structure for Secondary Battery Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional secondary battery connection process is labor-intensive and time-consuming due to vertically disposed conductive portions under the cover plate, making it difficult to achieve a secure electrical connection between anode/cathode terminals and conductive portions.
Innovation Solution
Bendable conductive portions are disposed horizontally under the cover plate with extended connecting portions from the terminals for horizontal electrical connection, maximizing contact area and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive portions are disposed vertically under the cover plate and battery cells are soldered one by one, then electrical connection is achieved, but assembly time and labor cost increase significantly
Solution Approach 1:
Multiple battery cells are connected to conductive portions simultaneously through a unified soldering process rather than individually. The conductive portions are extended horizontally to allow multiple connection points to be soldered at once, merging multiple assembly operations into one efficient step.
Solution Approach 2:
The conductive portions are extended horizontally from their traditional vertical orientation under the cover plate. This dimensional change allows battery cells to be connected in parallel along the horizontal axis, enabling simultaneous multi-point soldering and significantly improving assembly efficiency.
2Ease of manufacture
If conventional vertical connection structure is used, then assembly is straightforward, but electrical connection tightness and reliability are insufficient
Solution Approach 1:
The conductive portions are designed with flexibility to be bent into the optimal horizontal configuration. This dynamic adjustability allows the connection structure to adapt to the specific layout of battery cells while maintaining reliable electrical contact, combining ease of assembly with connection reliability.
3Reliability
If multiple individual soldering operations are performed, then each connection can be made, but time consumption and labor requirements increase
Solution Approach 1:
The horizontal extension of conductive portions enables multiple battery cell terminals to be soldered to the same conductive portion simultaneously. This merges multiple sequential soldering operations into a single parallel operation, dramatically reducing assembly time while maintaining reliable electrical connections for all cells.

AI summary
A conductive connection structure for secondary batteries employs conductive portions disposed under two lateral sides of a cover plate to conductively connect to at least one battery cell. The conductive portions disposed under the two lateral sides of the cover plate are bendable, and the conductive portions are bent toward outer sides of the cover plate, so that the conductive portions are disposed horizontally; a connecting portion is extended upward respectively from an anode and a cathode terminals on two lateral sides of each of the battery cells, and the connecting portions and the conductive portions are electrically connected. By modifying the design of the connection structure of the battery cells and the two conductive portions under the cover plate, a time for soldering the battery cells and the conductive portions for conductive connection is reduced, the connection is tighter and more reliable and manpower cost is reduced.
