Solution Overview
Problem
Oxide solid electrolytes face challenges during membrane formation due to cohesive forces leading to issues like overflow, cohesion, shrinkage, warping, and peeling, and poor adhesion to carriers, which can cause structural damage.
Innovation Solution
A carrier structure comprising a substrate with a low thermal shrinkage rate, a functionalized bonding layer, and a silicone-grafted resin layer is used to enhance adhesion and surface energy matching, allowing for effective coating and easy detachment of oxide solid electrolyte membranes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If oxide solid electrolyte is coated on existing carrier, then membrane formation is achieved, but macroscopic changes such as overflow, cohesion, shrinkage, warping, and peeling occur
Solution Approach 1:
The patent introduces a specially designed carrier with modified surface properties as an intermediary between the oxide solid electrolyte membrane and the substrate. This carrier acts as a mediator that provides appropriate surface energy and mechanical properties to prevent direct adverse interactions, thereby eliminating overflow, cohesion, shrinkage, warping, and peeling issues during membrane formation.
Solution Approach 2:
The patent modifies key parameters of the carrier including surface energy, thermal expansion coefficient, and mechanical strength to match and support the oxide solid electrolyte membrane. By adjusting these parameters, the carrier creates optimal conditions for membrane formation while preventing structural defects and maintaining stability throughout the process.
2Ease of manufacture
If surface energy of existing carrier and oxide electrolyte membrane do not match, then adhesion is poor, but membrane detachment causes structural damage
Solution Approach 1:
The patent precisely controls the surface energy parameter of the carrier to achieve optimal adhesion to the oxide solid electrolyte membrane. The carrier's surface energy is engineered to provide strong bonding during manufacturing while allowing clean detachment afterward, preventing structural damage to the membrane. This parameter optimization enables both easy manufacture and structural integrity preservation.
