Abstract:
1. A lithium battery comprising: a separator/electrode assembly, wherein said assembly comprises a current collector layer interposed between a first electrode layer and a second electrode layer of the same polarity and a porous separator layer on the side of each of said first and second electrode layers on the side opposite to said current collector layer, wherein each of said electrode layers is coated directly on one of said porous separator layers from a pigment dispersion comprising an organic solvent or water, at least one of said separator layers comprises inorganic oxide particles in an amount greater than 30% by weight, wherein there are no pores larger than 0.2 microns in diameter in the porous separator layer and the porous separator layer comprises a xerogel layer; an electrode, wherein said electrode comprises a current collector layer interposed between two electrode layers of the opposite polarity to said first and second electrode layers of the same polarity; and an electrolyte, wherein said battery comprises alternating layers of said separator/electrode assembly and said electrode.
