Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for electrode plates in secondary batteries face challenges such as high consumption of punching oil, leading to increased operating costs and equipment contamination, as well as inefficiencies in applying punching oil only to necessary regions during the notching process.
Innovation Solution
A method involving a stamp punching oil applicator that uses pads made of porous materials, such as polyurethane, to apply a controlled amount of punching oil precisely to the uncoated portions of the electrode plate, optimizing the application pattern to minimize waste and improve process efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If punching oil is applied to the entire uncoated portion using conventional methods, then the notching process can be performed, but the consumption of punching oil increases and equipment contamination occurs
Solution Approach 1:
The patent applies punching oil only to specific regions where it is actually needed for the notching process, rather than uniformly across the entire uncoated portion. The stamp block is designed with oil application regions that correspond precisely to the cutting section and non-electrode section, leaving the electrode section without oil application. This localized approach reduces punching oil consumption while ensuring adequate lubrication where required.
Solution Approach 2:
The uncoated portion is divided into distinct sections (cutting section, non-electrode section, and electrode section), and punching oil is applied selectively to only some of these sections. The stamp block is correspondingly segmented into oil application regions and non-oil application regions, allowing precise control over where punching oil is deposited during the notching process.
2Reliability
If punching oil is applied to the entire uncoated portion, then the notching process can be performed, but operating costs increase
Solution Approach 1:
The stamp block is designed with selective oil application regions that match the specific areas requiring lubrication during notching. By applying punching oil only to the cutting section and non-electrode section rather than the entire uncoated portion, the patent reduces material consumption and associated operating costs while maintaining adequate lubrication for the notching process.
3Reliability
If punching oil is applied to the entire uncoated portion, then the notching process can be performed, but equipment contamination increases
Solution Approach 1:
The patent implements selective punching oil application to specific regions (cutting section and non-electrode section) using a segmented stamp block design. This localized approach prevents punching oil from being applied to areas where it is not needed, thereby reducing the amount of oil that can contaminate equipment and environment while still providing sufficient lubrication for the notching operation.
4Loss of substance
If punching oil is applied to partial regions only, then punching oil consumption is reduced, but the notching process may be affected
Solution Approach 1:
The stamp block is designed with oil application regions that precisely match the areas requiring lubrication during notching (cutting section and non-electrode section). This targeted approach ensures that punching oil is applied only where it is needed for the notching process, reducing overall consumption while maintaining adequate lubrication for reliable operation.
Solution Approach 2:
The stamp block is pre-configured with specific regions designed to apply punching oil during the notching process. By having the oil application regions predetermined and integrated into the stamp block structure, the system ensures that punching oil is applied at the correct locations and times, optimizing both consumption and process reliability.

AI summary
A method for manufacturing electrode plate for secondary battery includes feeding an electrode plate including an active material layer and an uncoated portion to a stamp block on which a pad is formed, applying a punching oil absorbed by the pad to a partial region of the uncoated portion, and notching the electrode plate along the partial region where the punching oil is applied.
