Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems face challenges in efficiently eliminating hydrogen sulfide gas generated by sulfur-based materials without reducing the volume energy density or complicating the production process, and struggle to control the exhaust path effectively.
Innovation Solution
A battery design featuring an outer packaging with a communicating port, a hydrogen sulfide eliminator, and an exhausting unit, where the eliminator is integrated into the packaging rather than within the battery cells, allowing for efficient hydrogen sulfide removal without increasing the battery's thickness or volume, and enabling controlled exhaust path design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hydrogen sulfide eliminator is integrated into the outer packaging rather than within battery cells, then hydrogen sulfide elimination efficiency is improved and volume energy density is maintained, but the complexity of the packaging structure increases
Solution Approach 1:
The hydrogen sulfide eliminator is merged with the outer packaging structure, combining the packaging function with the gas elimination function into a single integrated system, thereby improving elimination efficiency without adding separate components
Solution Approach 2:
The outer packaging is designed to serve multiple functions: protecting the battery cells and enabling hydrogen sulfide elimination through the integrated eliminator, thus achieving multi-functionality without increasing overall system complexity
2Ease of operation
If the communicating port is designed with integrated exhaust management, then hydrogen sulfide exhaust path control is improved, but the packaging design complexity increases
Solution Approach 1:
The exhaust management function is extracted and integrated into the communicating port design, allowing targeted control of hydrogen sulfide exhaust paths through a dedicated structure rather than requiring complex external systems
Solution Approach 2:
Instead of adding complex external exhaust control systems, the patent inverts the approach by integrating exhaust management directly into the communicating port, simplifying the overall system while maintaining effective control
3Quantity of substance
If the hydrogen sulfide eliminator is placed outside the battery cells, then the battery volume energy density is maintained, but the exhaust path management becomes more complex
Solution Approach 1:
The eliminator is merged with the outer packaging and communicating port structures, combining multiple functions into integrated components that maintain compact design while enabling effective exhaust path management
