Battery Discharge Container With Staggered Plates to Prevent Floating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lithium-ion secondary batteries often float during the discharge treatment process, risking fire when not completely discharged, as they come into contact with the atmosphere.
Innovation Solution
A pretreatment container with a housing and staggered, rotatably hinged upper plates that create an inclined insertion portion to prevent floating, ensuring the battery remains submerged and preventing contact with air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the secondary battery is immersed in a solution for discharge treatment, then the discharge operation can be performed, but the battery may float and come into contact with the atmosphere causing fire
Solution Approach 1:
The patent introduces an intermediary structure (the container with upper plates and insertion portion) between the battery and the atmosphere. This intermediary prevents direct contact between the floating battery and atmospheric oxygen, thereby eliminating the fire hazard while maintaining the discharge treatment function.
Solution Approach 2:
The container creates a controlled environment that isolates the battery from the atmospheric atmosphere during discharge treatment. By limiting contact with atmospheric oxygen through the specialized container structure, the system effectively creates an inert environment that prevents combustion even when the battery floats.
2Ease of operation
If the upper plates are made rotatably hinged to allow battery insertion, then the ease of operation is improved, but the structural complexity increases
Solution Approach 1:
The upper plates are designed with rotatable hinges that allow dynamic movement between open and closed positions. This dynamic structure enables easy battery insertion and removal while maintaining the containment function during discharge treatment, resolving the contradiction between operational ease and structural complexity.
3Adaptability or versatility
If the insertion portion is created between staggered upper plates, then the battery can be inserted for treatment, but the structure becomes more complex
Solution Approach 1:
The upper plates are arranged in a staggered asymmetric configuration rather than a symmetric overlapping arrangement. This asymmetric design creates the insertion portion while using fewer plates and simpler geometry, thereby reducing structural complexity compared to conventional symmetric designs.
