Progress toward Electrochemistry Intensified by using Supergravity Fields

Supergravity fields with high gravity acceleration can promote interphase ship velocity and convection velocity. Over the past decade, research has been devoted to enhancing electrochemical reactions by using supergravity fields. The enhancement of electrochemical reactions is ascribed to the acceleration of mass transfer and bubble separation. In this Minireview, the intensification kinetics of a supergravity field on mass transfer and bubble separation during electrochemical reactions are analyzed theoretically. The progress in terms the enhancement of electrochemical reactions (such as metal electrodeposition, water electrolysis, and chloralkali electrolysis) under a supergravity field is reviewed. The structures and properties of functional films electrodeposited under a supergravity field on both the cathode and the anode are summarized. The Minireview is helpful to understand the effect of the mechanism of the supergravity field on electrochemical reactions and to expand potential applications.
