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.
