Electrolyte Flow Channel Layout for Uniform Electrode Humidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage devices face challenges in achieving uniform humidity distribution within the electrode assembly, which can affect the performance and efficiency of the device.
Innovation Solution
The energy storage device incorporates a specific design featuring a housing with an opening for electrolyte, an electrode assembly, a top cover with a liquid injection hole, and a lower plastic member with bosses and a notch. This configuration creates a flow channel for the electrolyte, ensuring it flows uniformly to the electrode assembly through the insulating adhesive sheet and connecting plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrolyte is filled into the housing, then the energy storage device can operate, but the humidity distribution within the electrode assembly becomes non-uniform
Solution Approach 1:
The patent divides the electrolyte filling process into multiple flow channels created by the notches on the bosses. Instead of a single filling path, the electrolyte is distributed through multiple channels (first flow channel, second flow channel, etc.) that lead to different regions of the electrode assembly, ensuring uniform humidity distribution while maintaining operational capability
Solution Approach 2:
The notches are strategically positioned on the bosses at specific locations within the housing to create localized flow channels. This ensures that electrolyte is delivered to specific regions of the electrode assembly that require it, achieving local humidity uniformity while maintaining overall device operation

Function Achieved in This Case
The design enhances the flow rate and uniformity of the electrolyte to the electrode assembly, improving the humidity distribution and overall performance of the energy storage device.
Implementation Method 1
the insulating adhesive sheet, the connecting plate and the edge enclose to form a first flow channel for the electrolyte, and the electrolyte is injected through the liquid injection hole and flows towards the electrode assembly through the first flow channel
