DEVICE USING A POROUS POLYMERIC SEPARATOR HAVING CHARGED FUNCTIONAL GROUPS AND FORMING A CONTINUOUS THREE-DIMENSIONAL NETWORK

Abstract

The invention relates to an electrochemical device comprising: - two electrodes; - a spacer, placed between the two electrodes, made of a porous polymer material forming a continuous three-dimensional network, having a porosity greater than 70%, preferably greater than 80%, whose pores are interconnected, and possessing charged surface functional groups; - an electrolytic solution comprising a solute in the form of a dissolved salt and impregnating the pores of said spacer; - and a device D for harvesting the electrical energy generated by a potential difference existing between the two electrodes or for applying a potential difference between the two electrodes. Said device is intended for implementing an ion transfer process within said device.
