Abstract
Provided are methods of preparing lithium batteries comprising a separator/electrode assembly having one or more current collector layers interposed between first and second electrode layers of the same polarity, wherein the first electrode layer is coated or laminated overlying a separator layer and the separator/electrode assembly is interleaved with an electrode comprising a current collector layer interposed between two electrode layers of opposite polarity to said first and second electrodes.
