Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid-state electrolytes are sensitive to moisture, carbon dioxide, and oxygen, which can lead to degradation, necessitating measures to protect them during storage and transportation.
Innovation Solution
A container assembly with a sealed chamber containing a solid-state electrolyte and a hydrophobic substance, such as oil or organic solvents, is used to prevent exposure to moisture and contaminants, with the hydrophobic substance sealing the chamber and protecting the electrolyte.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solid-state electrolyte is exposed to air during storage and transportation, then handling and operation are simplified, but the electrolyte degrades due to moisture, carbon dioxide and oxygen
Solution Approach 1:
A hydrophobic substance is introduced as an intermediary between the solid-state electrolyte and the air environment. This substance allows the electrolyte to be handled in ambient conditions while blocking harmful substances (moisture, CO2, oxygen) from reaching the electrolyte surface, thus resolving the contradiction between ease of handling and electrolyte stability.
2Reliability
If hydrophobic substance is used to protect solid-state electrolyte, then protection from environmental contaminants is improved, but device complexity increases
Solution Approach 1:
The hydrophobic substance forms a protective layer (film) around the solid-state electrolyte, either as a coating or as a surrounding medium in a sealed container. This thin film approach provides effective protection while minimizing the added complexity compared to rigid multi-component protective systems.
3Reliability
If hydrophobic substance surrounds solid-state electrolyte, then shielding from contaminants is improved, but separation and removal become difficult
Solution Approach 1:
The hydrophobic substance is selected to be easily removable or disposable after serving its protective function. This allows the substance to provide effective shielding during storage and transport, then be简单地 removed or discarded without complicating the manufacturing process or requiring complex separation systems.
