Preparation and Performance Characterization of a Large Area ScSZ Electrolyte Substrate

摘要

A thin ScSZ electrolyte with a large area was synthesized using the tape-casting method. The conductivity of 0.095 S cm~(-1) at 800 ℃ was achieved. The maximum power density of a single cell reached 368 mW cm~(-1) at 800℃. To make a large electrolyte battery more suitable, our study improves the casting method of preparing a dense, porous electrolyte substrate that promotes surface roughness of the electrolyte. However, it is difficult to control the thickness of the substrate, meaning that further improvements are needed.
