Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional electrode design is used, then manufacturing simplicity is maintained, but charge and discharge efficiency is insufficient
Solution Approach 1:
The electrode structure is segmented into multiple functional layers: substrate layer, intermediate layer, and channel layer. This segmentation allows each layer to perform specific functions - the substrate provides structural support, the intermediate layer facilitates ion transport, and the channel layer enhances electrolyte interaction - thereby improving charge and discharge efficiency while maintaining manageable complexity through functional specialization
Solution Approach 2:
Different regions of the electrode structure are assigned different material compositions and properties. The channel layer contains aluminum chloride with specific crystal structures (NaCl-type or FeCl2-type) that create localized ion channels, while the intermediate layer has different compositional characteristics. This local quality differentiation optimizes ion transport pathways and electrolyte interaction at specific locations, enhancing overall battery efficiency
2Reliability
If channel layer with aluminum chloride is introduced, then ion channel structure is enhanced, but manufacturing process complexity increases
Solution Approach 1:
The channel layer is pre-formed on the substrate before final electrode assembly. The aluminum chloride is deposited and allowed to form the desired crystal structure (NaCl-type or FeCl2-type) in advance, creating ready-made ion channels. This preliminary action ensures reliable ion channel structure is established before the electrode is integrated into the battery, improving reliability while allowing standardized manufacturing processes
Solution Approach 2:
The electrode structure uses composite material composition with the channel layer containing aluminum chloride combined with other materials in the intermediate and substrate layers. This composite structure provides both the structural integrity needed for manufacturing and the specific ion channel properties required for reliable ion transport, balancing manufacturing feasibility with structural reliability
