A process for producing a lithium battery, comprising: (A) Preparing a plurality of conductive porous layers, wet anode layers, and wet cathode layers; (B) Stacking a desired number of porous layers and wet anode layers in an alternating manner to form an anode electrode having a thickness no less than 100 μm; (C) Placing a porous separator layer in contact with the anode electrode; (D) Stacking a desired number of porous layers wet cathode layers in an alternating manner to form a cathode electrode in contact with the porous separator, wherein the cathode electrode has a thickness no less than 100 μm; and (F) Assembling and sealing the anode electrode, separator, and cathode electrode in a housing to produce the lithium battery. The consolidated anode or cathode layer is preferably thicker than 300 μm more preferably thicker than 400 μm, and further more preferably greater than 500 μm.
