Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air battery modules face challenges in achieving a balance between high output and downsizing, particularly when used in vehicles, as they become larger and less efficient due to the need for multiple batteries connected in series.
Innovation Solution
The air battery module design features a housing with multiple power sections, where each section comprises an anode, a cathode arranged outside, and an electrolyte layer, sharing a single electrolytic solution that dissolves oxygen, allowing for efficient oxygen introduction and minimizing module volume through a cylindrical shape and close-packed arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple air batteries are connected in series to achieve high output power, then the power output increases, but the module size becomes larger
Solution Approach 1:
Multiple power sections share a single electrolytic solution reservoir instead of each having its own separate electrolyte. This merging of the electrolyte system allows multiple battery cells to be connected in series for high power output while sharing common space, thereby reducing the overall module size
Solution Approach 2:
The single electrolytic solution serves multiple functions: it acts as the electrolyte for all power sections simultaneously, provides a common oxygen source for all cathodes, and eliminates the need for separate electrolyte reservoirs for each cell, achieving both high power and compact size
2Productivity
If the cathode is arranged outside the power section, then the contact area with electrolytic solution increases and oxygen introduction efficiency improves, but the structural complexity increases
Solution Approach 1:
The cathode is moved from an internal position to an external position surrounding the power section, utilizing the outer surface area of the cylindrical structure. This dimensional repositioning maximizes the cathode's contact area with the electrolytic solution for efficient oxygen introduction while maintaining a simple cylindrical geometry
