Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional plating methods are used in redox flow batteries, then the negative electrode can be formed, but the plated layers are non-uniform and cracked, limiting energy storage capacity
Solution Approach 1:
A plating additive is introduced as an intermediary substance in the negative electrolyte that mediates the plating process. The additive interacts with cations to form complexes that plate onto the negative electrode in self-assembled monolayers, producing uniform and crack-free plated layers while enabling increased energy storage capacity.
Solution Approach 2:
The plating additive changes the chemical parameters of the electrolyte by forming complexes with cations. This parameter change modifies the plating mechanism to produce self-assembled monolayers, resulting in uniform, thick plated layers without cracks, thereby resolving the contradiction between manufacturing precision and energy storage capacity.
2Quantity of substance
If thicker plated layers are formed on the negative electrode, then energy storage capacity increases, but the plated layers become non-uniform and cracked
Solution Approach 1:
The plating additive serves as a mediator that enables the formation of thick plated layers while maintaining uniformity. By forming complexes with cations and facilitating self-assembled monolayer formation, the additive allows thick plating without the development of cracks or non-uniformities.
Solution Approach 2:
The plating process utilizes self-assembled monolayers that form automatically through the interaction of the plating additive with cations. This self-organizing mechanism ensures uniform deposition of thick plated layers without requiring external intervention to maintain precision.
3Ease of manufacture
If conventional materials are used in redox flow batteries, then the system is simple and earth-abundant, but the cost of storage is high
Solution Approach 1:
The introduction of a plating additive changes the chemical parameters of the electrolyte to enable more efficient plating. This parameter change allows for increased energy storage capacity in the negative electrode while maintaining the use of simple, earth-abundant materials, thereby improving the energy storage to cost ratio.
