LITHIUM BATTERIES UTILIZING NANOPOROUS SEPARATOR LAYERS

摘要

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.

1. A method of making a lithium battery, the method comprising the steps of:
(a) coating a porous separator layer on a substrate; (b) coating or laminating a first electrode layer of a polarity overlying said separator layer; (c) coating or laminating a second electrode layer of the same polarity overlying said separator layer; (d) coating, laminating, or depositing one or more current collector layers overlying said first electrode layer to make a separator/electrode stack; (e) laminating said second electrode layer to said one or more current collector layers on the side opposite to said first electrode layer and delaminating said substrate from said separator layer to form a separator/electrode assembly having said one or more current collector layers interposed between said first and second electrode layers; and (f) interleaving said assembly with an electrode comprising a current collector layer interposed between two electrode layers of opposite polarity to said first and second electrode layers of steps (b) and (c) to form a dry cell.
