Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If alkaline electrolytes are used in zinc-manganese dioxide batteries, then energy density is improved, but corrosion resistance deteriorates
Solution Approach 1:
A protection structure comprising a protection layer is introduced as an intermediary between the metal electrode layer and the alkaline electrolyte. This protection layer prevents direct contact between the electrolyte and the metal electrode, thereby eliminating corrosion while allowing ionic transport to maintain energy density.
Solution Approach 2:
The battery structure is segmented into distinct functional layers: a metal electrode layer, a protection layer, and an electrochemically active portion. This segmentation allows the protection layer to specifically address corrosion resistance without compromising the energy storage function of the electrochemically active portion.
2Adaptability or versatility
If thin film battery designs are used for flexible energy storage, then adaptability is improved, but current output capability deteriorates
Solution Approach 1:
The battery employs a composite structure combining a metal electrode layer with a protection layer and electrochemically active materials. This composite design enables the thin film battery to achieve both flexibility and enhanced current output capability by optimizing the properties of each layer.
Solution Approach 2:
The invention changes key parameters of the battery structure including the introduction of a protection layer with specific thickness and material properties, and optimization of the electrochemically active portion to increase surface area and ionic conductivity, thereby improving current output while maintaining flexibility.
