Abstract

A process is described for fabricating an electrolyte-electrode composite suitable for high energy alkali metal battery that includes mixing composite electrode materials with excess liquid, such as ethylene carbonate or propylene carbonate, to produce an initial formulation, and forming a shaped electrode therefrom. The excess liquid is then removed from the electrode to compact the electrode composite which can be further compacted by compression. The resulting electrode exhibits at least a 75% lower resistance.

Methods to fabricate variations in porosity of lithium ion battery electrode films

Patent Brown, Karl M.; Bolandi, Hooman; Pebenito, Victor; ...

A method and apparatus for forming lithium-ion batteries and battery cell components, and more specifically, to a system and method for fabricating such batteries and battery cell components using deposition processes that form three-dimensional porous structures are provided. One method comprises texturing a conductive substrate by calendering the conductive substrate between opposing wire mesh structures, forming a first layer of cathodically active material having a first porosity on the surface of the textured conductive substrate, and forming a second layer of cathodically active material having a second porosity on the first layer, wherein the second porosity is greater than themore » first porosity. « less

Method of electrode fabrication and an electrode for metal chloride battery

Patent Bloom, I D; Nelson, P A; Vissers, D R

A method of fabricating an electrode for use in a metal chloride battery and an electrode are provided. The electrode has relatively larger and more uniform pores than those found in typical electrodes. The fabrication method includes the steps of mixing sodium chloride particles selected from a predetermined size range with metal particles selected from a predetermined size range, and then rigidifying the mixture. The electrode exhibits lower resistivity values of approximately 0.5 [Omega]cm[sup 2] than those resistivity values of approximately 1.0-1.5 [Omega]cm[sup 2] exhibited by currently available electrodes.
