초록 ▼

The present invention pertains to methods of preparing prismatic cells which comprise the steps of winding lithium metal anode, separator, and cathode layers on a rounded mandrel having a large circumference relative to the external dimensions of the prismatic cell stack and of compressing the multilayer rounded cell stack into a prismatic shape and then filling the prismatic subassembly with electrolyte to form a prismatic ell stack, or alternatively of winding into such a rounded cell stack and filling with electrolyte and then compressing into a prismatic cell stack, prior to enclosing the prismatic cell stack in a barrier material film and sealing to form the casing of the prismatic cell. The present invention also pertains to electric current producing cells prepared according to such methods.

[ What is claimed is:] [1.] A method of preparing a multilayer electric current producing cell, said cell comprising a casing and a prismatic cell stack, said prismatic cell stack having an external length dimension, an external width dimension, an external thickness dimension, two substantially parallel flat surfaces, and outside permeable surfaces; which method comprises, in order, the steps of:(a) providing a laminar combination of:(i) an anode comprising an anode active layer, which layer comprises an anode active material comprising lithium;(ii) a solid composite cathode comprising a cathode active layer, which layer comprises a cathode active material, said cathode active layer having a first surface and a second opposite surface, said solid composite cathode further comprising a non-permeable current collector in contact with said first surface of said cathode active layer; and,(iii) a separator interposed between said anode and said solid composite cathode, and in contact with said second surface of said cathode active layer;wherein said anode active layer and said cathode active layer are positioned in a face-to-face relationship;(b) winding said combination on a mandrel having a cross-section of a rounded shape and having a circumference selected from the lengths consisting of:(i) 140 to 200 per cent of the difference between said external length dimension and said external thickness dimension of said prismatic cell stack; and,(ii) 140 to 200 per cent of the difference between said external width dimension and said external thickness dimension of said prismatic cell stack;said winding forming a rounded anode-separator-solid composite cathode subassembly having a jellyroll configuration and a rounded shape;(c) removing said mandrel from said rounded subassembly;(d) compressing said rounded subassembly in a press to form a prismatic subassembly having two substantially parallel flat surfaces;(e) removing said prismatic subassembly from said press;(f) contacting said prismatic subassembly with a source of a liquid nonaqueous lithium salt electrolyte to form said prismatic cell stack, wherein said electrolyte substantially fills porous areas within said prismatic cell stack;(g) removing said prismatic cell stack from contact with said source of electrolyte;(h) enclosing said prismatic cell stack in a barrier material film; and,(i) sealing said film to form said casing.
