Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple anodes are arranged in the electrolytic cell, then production capacity increases, but current distribution becomes non-uniform
Solution Approach 1:
The cathode is divided into multiple independent cathode sheets (at least two), each corresponding to one or more anodes. This segmentation allows current to be distributed more uniformly across multiple cathode-anode pairs rather than concentrating through a single cathode, thereby maintaining stable current distribution while increasing production capacity through parallel electrolysis reactions.
2Object-affected harmful factors
If a protective hood is arranged above the electrolytic cell to reduce chlorine leakage, then chlorine collection effect deteriorates
Solution Approach 1:
The collecting hood is selectively positioned only above the cathode area where metal product accumulates, while leaving the anode replacement area open. This extraction approach allows the hood to collect chlorine gas generated during electrolysis without requiring complete enclosure, thereby maintaining effective chlorine collection while providing access for anode replacement operations.
Solution Approach 2:
The collecting hood acts as an intermediary structure that captures chlorine gas through negative pressure generated by a vacuum pump. This mediator approach allows chlorine to be collected and controlled without requiring direct physical enclosure of the entire cell, enabling both chlorine management and operational access.
3Ease of operation
If manual anode replacement is performed, then operational flexibility is maintained, but workload and safety risks increase
Solution Approach 1:
The anodes are designed with self-lubricating properties through specific material selection and surface treatment, enabling them to be replaced without manual intervention. The anode replacement mechanism operates automatically through the existing mechanical structure, allowing the system to service itself by replacing worn anodes without requiring worker entry into the electrolytic cell, thereby reducing workload and safety risks while maintaining operational flexibility.

AI summary
A multi-anode electrolytic cell relating to molten salt lithium electrolysis. The cell includes a sealed container with at least two electrode groups uniformly arranged inside. Each group has an anode and a cathode, and the top end of the anode penetrates the top end of the sealed container to protrude out of the sealed container. A separation mesh is arranged on the outer side of the anode. The cathode is arranged on the outer side of the separation mesh and connected with a conducting plate. The top end of the conducting plate protrudes out of the top end of the sealed container. A bottom-removed collecting hood is arranged above the cathode such that it surrounds the outer side of the anode. The physical fields in the sealed container are uniformly distributed by uniformly arranging the electrode groups, thereby ensuring a continuous and stable electrolysis process.
