Method of producing deformable quasi-solid electrode material for alkali metal batteries

Abstract

A method of preparing an alkali metal cell having a quasi-solid electrode, the method comprising: (a) combining a quantity of an active material, a quantity of an electrolyte, and a conductive additive to form a deformable and electrically conductive electrode material, wherein the conductive additive, containing conductive filaments, forms a 3D network of electron-conducting pathways; (b) forming the electrode material into a quasi-solid electrode, wherein the forming step includes deforming the electrode material into an electrode shape without interrupting the 3D network of electron-conducting pathways such that the electrode maintains an electrical conductivity no less than 10−6 S/cm; (c) forming a second electrode; and (d) forming an alkali metal cell by combining the quasi-solid electrode and the second electrode having an ion-conducting separator disposed between the two electrodes.
