Abstract
Electrolyte solution is often encountered in many energy related devices, i.e., Li/Air batteries and electrolyzers. However, mass transport phenomena of Li/Air batteries are not completely clarified. We visualized mass transport phenomena in an aqueous solution of lithium chloride as an electrolyte of a Li/Air battery by using MRI. We visualized ionic transportations in the electrolyte by measuring water molecules' transportations. We electrolyzed LiClaq using a pair of carbon electrodes and a pair of copper electrodes. When LiClaq was electrolyzed using carbon electrodes, the convection like Benard cells was observed. Similarly, when we used copper electrodes, the density induced convection by copper ions was observed.
