Battery Electrode Plate Identification Layer for Surface Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in accurately identifying and distinguishing the asymmetrically coated surfaces of battery electrode plates in battery cell assemblies leads to potential assembly errors and production of disqualified batteries during automated production.
Innovation Solution
Incorporating an identification layer on at least one surface of the battery electrode plate, which differs in shape or position from the active material layer, allowing for accurate visual or machine-based identification and ensuring correct positioning and assembly of the battery electrode plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If asymmetric coating is applied to both surfaces of the electrode plate to meet performance requirements, then battery performance is improved, but the ability to visually distinguish the two surfaces is lost
Solution Approach 1:
The patent applies a visual identification mark (different in color, pattern, or appearance) on one surface of the electrode plate. This allows the two surfaces to be easily distinguished by color or visual characteristics, resolving the contradiction between having identical asymmetric coatings for performance and needing visual differentiation for assembly.
2Manufacturing precision
If identical asymmetric coatings are applied to both surfaces, then manufacturing consistency is improved, but assembly accuracy deteriorates due to inability to distinguish surfaces
Solution Approach 1:
By adding a visual identification mark (color, pattern, or visual difference) to one surface while maintaining identical asymmetric coatings on both surfaces for performance, the patent achieves both manufacturing consistency and assembly accuracy. The visual mark does not interfere with the coating performance but enables correct orientation during assembly.
3Device complexity
If no identification mark is added to maintain simple structure, then device complexity is reduced, but productivity decreases due to assembly errors
Solution Approach 1:
The patent adds a simple visual identification mark (color or pattern) to the electrode plate surface, which minimally increases structural complexity but dramatically improves assembly efficiency by enabling quick visual identification of the correct surface orientation, preventing assembly errors and rework.

AI summary
A battery electrode plate includes an electrode plate body, and each of two surfaces of the electrode plate body is provided with an active material layer. The battery electrode plate further includes an identification layer. The identification layer is arranged on at least one surface, and the coatings on the two surfaces are different in shape or position.
