Power Storage Module Electrolyte Filling During Vertical Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the manufacturing of power storage modules, maintaining the electrodes in a vertical laminated state poses challenges in preventing electrolytic solution from leaking out, especially when the laminate is conveyed or processed.
Innovation Solution
A method involving a placing step where the laminate is positioned on a conveyance palette with electrodes laminated vertically, followed by connecting a flow channel unit to the laminate's opening, supplying the electrolytic solution through this unit, and then conveying the laminate while keeping the flow channel unit connected to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the laminate is conveyed or processed with electrodes laminated in the vertical direction, then handling ease is improved, but electrolytic solution leakage occurs from the opening
Solution Approach 1:
The flow channel unit is connected to the opening before electrolytic solution supply, and remains connected during conveyance and processing steps. This preliminary connection prevents leakage by ensuring the opening is already sealed and ready for solution supply, eliminating the need to disconnect and reconnect during subsequent operations.
Solution Approach 2:
The flow channel unit acts as an intermediary component that bridges the opening and the electrolytic solution supply system. It serves as a temporary seal and connection interface that remains in place during conveyance, allowing the laminate to be handled vertically while preventing solution leakage through the opening.
2Stability of the object's composition
If the opening is opened in the horizontal direction while electrodes are vertically laminated, then conveyance stability is improved, but leakage risk increases
Solution Approach 1:
The flow channel unit is pre-connected to the horizontally oriented opening before electrolytic solution supply. This preliminary connection ensures that even though the opening faces horizontally for stable conveyance, the leakage risk is prevented by having the flow channel unit already in place as a sealed interface.
Solution Approach 2:
The flow channel unit serves as an intermediary that allows the opening to maintain its horizontal orientation for stable conveyance while simultaneously preventing leakage. It mediates between the need for horizontal opening orientation and the need to prevent solution leakage during vertical conveyance.

AI summary
A method for manufacturing a power storage module includes: a placing step of placing an electrode laminate on a restraint member so that a laminating direction runs along a vertical direction; a connecting step of connecting a first connection part so that a connecting portion of a second connection part with respect to a connected part is positioned on an upper side in the vertical direction than an opening; a supplying step of connecting a distal end part of a supply pipe for an electrolytic solution to the second connection part, and supplying the electrolytic solution to a space; and a conveying step of removing a recessed part of the supply pipe from the second connection part, and conveying a cell stack placed on the restraint member in a state in which the opening is connected to the first connection part.
