Title: REDOX CELL
Abstract:
The present invention addresses the problem of providing a redox cell that inhibits rises in the cell internal resistance due to a decrease in conductivity and an increase in the viscosity and solution resistance in a high-concentration active material liquid, and makes it possible to improve the charging/discharging efficiency. The present invention is characterized in that the redox cell is provided with a positive electrode 11 in which a positive electrode active material liquid is impregnated or circulated, a negative electrode 21 in which a negative electrode active material liquid is impregnated or circulated, and a barrier membrane 3 provided between the positive electrode 11 and the negative electrode 21, the positive electrode active material liquid and the negative electrode active material liquid both having an active material concentration of at least 1.8M, the barrier membrane 3 having an ion exchange capacity of at least 2.0 (meq/g - dry ion exchange membrane), and the membrane thickness being 120 µm or less.
