Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the preparation of oxide solid electrolyte membranes, cohesive forces in the oxide solid electrolyte lead to issues such as overflow, cohesion, shrinkage, warping, and peeling, making it difficult to form a high-quality membrane on a carrier, and the mismatch in surface energy between the carrier and the electrolyte membrane causes difficulty in detachment.
Innovation Solution
The development of an oxide solid electrolyte carrier comprising a substrate, a functionalized bonding layer, and a silicone-grafted acrylic resin coating, which provides a matching surface energy with the oxide solid electrolyte, allowing for effective coating and adherence of the electrolyte membrane on the carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If oxide solid electrolyte is coated on existing carrier, then coating process is simple, but membrane quality deteriorates due to shrinkage, warping, and peeling
Solution Approach 1:
The patent introduces a surface treatment layer as an intermediary between the oxide solid electrolyte membrane and the carrier. This treatment layer modifies the surface energy of the carrier to match the oxide electrolyte, preventing direct adverse interactions while maintaining coating simplicity and ensuring high membrane quality without shrinkage, warping, or peeling.
2Strength
If surface energy of carrier and oxide electrolyte membrane do not match, then coating adhesion is strong, but detachment becomes difficult and causes structural damage
Solution Approach 1:
The patent segments the interface between carrier and electrolyte membrane by introducing a surface treatment layer with specific surface energy characteristics. This layer provides controlled adhesion during coating while enabling easy detachment afterward, preventing structural damage to the membrane body during removal.
3Stability of the object's composition
If oxide solid electrolyte has cohesive forces, then material integrity is maintained, but coating uniformity deteriorates due to overflow and cohesion
Solution Approach 1:
The patent changes the surface energy parameter of the carrier through surface treatment, creating optimal interaction conditions with the oxide solid electrolyte. This parameter modification allows the cohesive forces in the electrolyte to be balanced, preventing overflow and cohesion defects while maintaining material integrity and achieving uniform coating.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed carrier system enables the formation of a high-quality oxide solid electrolyte membrane on the carrier without issues such as shrinkage, warping, or peeling, and facilitates easy detachment of the membrane from the carrier without causing structural damage.
Implementation Method 1
a surface energy of the existing carrier and the oxide electrolyte membrane does not match, which makes the oxide electrolyte membrane on the carrier difficult to be torn off from the carrier
Implementation Method 2
cohesive forces remain in the oxide solid electrolyte. When the oxide solid electrolyte is coated on an existing carrier, it is very easy to produce macroscopic changes such as overflow and cohesion
