METHOD OF PRODUCING ALKALI METAL OR ALKALI-ION BATTERIES HAVING HIGH VOLUMETRIC AND GRAVIMETRIC ENERGY DENSITIES

摘要

A process for producing an alkali metal battery, comprising: (a) preparing multiple conductive porous layers (having at least 80% by volume of pores), multiple wet anode layers of an anode active material mixed with a liquid electrolyte, and multiple wet cathode layers of a cathode active material mixed with a liquid electrolyte; (b) stacking and consolidating a desired number of the porous layers and a desired number of wet anode layers to form an anode electrode; (c) placing a porous separator layer in contact with the anode electrode; (d) preparing a cathode electrode in a similar manner than anode; and (e) assembling all the components in a housing to produce the battery; wherein the anode active material has a material mass loading no less than 20 mg/cm² in the anode and/or the cathode active material has a material mass loading no less than 30 mg/cm² in the cathode electrode.
