Electrical cells and batteries, method for manufacturing the same and method for improving the performances of electrical cells and batteries

Abstract

Disclosed is an electrical cell comprising a negative electrode, a positive electrode, and a deposition layer separating the positive electrode and a gas phase that supplies at least one reactive gas; wherein the deposition layer and the positive electrode are in communication with each other via electrolyte(s). Also disclosed is a battery comprising the electrical cell described above and a battery comprising: a cell comprising a negative electrode in communication with an anolyte and a positive electrode in communication with a catholyte; and a gas-liquid reactor, which is fed with the catholyte from the cell and a gas. Additionally, also disclosed is a method for improving the performances of a cell or battery comprising a negative electrode, a positive electrode, and a deposition layer separating the positive electrode and a gas phase that supplies at least one reactive gas, wherein the deposition layer and the positive electrode are in communication with each other via electrolyte(s), the method comprising: controlling reaction fronts away from the positive electrode by tuning the flux of compound(s) in the electrolyte(s), which can react with the reactive gas to form a solid, and/or the flux of the reactive gas.
