Battery Case Degassing with Adsorbent Compartment to Cut Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing area used for degassing portions in battery cases leads to higher production costs and reduced manufacturing efficiency due to increased waste and gas emissions.
Innovation Solution
Incorporating an adsorbent within the degassing portion of the battery case and forming an adsorbent compartment using a sealing portion to manage and contain the adsorbent, thereby reducing gas emissions and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the area used for degassing portion is increased, then the degassing operation can be performed more effectively, but the amount of waste that is cut and discarded increases, which increases production cost and reduces manufacturing efficiency
Solution Approach 1:
The patent converts the harmful gas generated during battery formation into a beneficial process by directing it through an adsorbent material. The gas that would otherwise be wasted is now captured and the degassing portion can be minimized, transforming a harmful emission problem into a solution that reduces both waste and production costs
Solution Approach 2:
Instead of simply discarding the degassing portion as waste, the patent recovers the adsorbent material after it has fulfilled its gas absorption function. The adsorbent can be regenerated and reused, converting a single-use waste material into a recoverable resource that reduces overall material consumption and production costs
2Object-generated harmful factors
If the area used for degassing portion is increased, then gas emissions can be managed, but the battery production cost increases and manufacturing efficiency decreases
Solution Approach 1:
The patent transforms the harmful gas emission problem into a benefit by using a compact adsorbent-based system. This allows effective gas management in a small space, converting what was previously a reason to increase degassing area into an opportunity to reduce it, thereby improving manufacturing efficiency while controlling emissions
Solution Approach 2:
The patent changes the physical and chemical parameters of the battery case by introducing adsorbent material with specific absorption properties. This parameter change allows the system to achieve the same gas management function with a much smaller degassing portion, improving productivity without compromising emission control
