Abstract:

The diaphragm material in the electrochemical reactor is a special material that separates the positive electrode and the negative electrode on the electronic path but keeps the ion transport path open. As one of the three critical materials in the electrochemical reactor, the separating diaphragm must be stable in the crucial acidic/basic, strong electric field strength, and other complex micro-environments. In this review, we focus on the molecular design of the separating diaphragm inside the electrochemical reactors. The mesoscopic strategies to regulate electrochemical properties and chemical stabilities of the separating diaphragm were discussed. The purpose of this review is to set up a link between the molecular structure of the separating diaphragm and the performances of the electrochemical reactors in terms of mesoscopic strategies.

Key words: molecular design, chemical composition, energy conversion, lithium sulfur battery, fuel cell
