Redox Flow Battery Tank Vertical Flow Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional redox flow battery systems face inefficiencies in quickly replacing electrolyte solution due to the mixing of used and fresh electrolyte solutions during simultaneous drainage and replenishment, which prolongs the replacement process and reduces efficiency.
Innovation Solution
The electrolyte solution tank incorporates a flow guide mechanism that directs the electrolyte solution vertically downward from the supply part to the drain part, preventing mixing of used and fresh solutions during simultaneous replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the used electrolyte solution is drained and the fresh electrolyte solution is introduced simultaneously in the conventional structure, then the replacement process can be performed faster, but the used electrolyte solution and the fresh electrolyte solution are mixed together which reduces the efficiency of electrolyte solution exchange
Solution Approach 1:
The interior chamber is divided into a first chamber and a second chamber by a partition wall. The first chamber receives fresh electrolyte solution through the supply part, while the second chamber drains used electrolyte solution through the drain part. This segmentation prevents mixing of fresh and used electrolyte solutions during simultaneous drainage and replenishment operations, thereby maintaining high exchange efficiency while enabling fast replacement.
2Quantity of substance
If additional electrolyte solution tanks are added to increase the battery capacity, then the battery capacity increases, but the device complexity and space requirement increase
Solution Approach 1:
The partition wall extends in the vertical direction to divide the interior chamber into multiple levels (first chamber above, second chamber below). This vertical dimensionality change allows the tank to store larger quantities of electrolyte solution without increasing the horizontal footprint, thereby increasing battery capacity while maintaining compact structure and avoiding additional tanks.

AI summary
An electrolyte solution tank has a tank body, an electrolyte solution supply part, and electrolyte solution drain part and a flow guide mechanism. The electrolyte solution supply part supplies the electrolyte solution into an interior chamber in the tank body. The electrolyte solution is drained from the tank body to the outside of the tank through the electrolyte solution drain part. The flow guide mechanism is arranged in the interior chamber of the tank body. The flow guide mechanism guides the flow of the electrolyte solution in the interior chamber to the electrolyte solution drain part along a vertically downward direction.
