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.
Claims23
A method of making a multilayer structure for use in a lithium battery, the method comprising the steps of:
- (a) providing a porous separator;
- (b) placing a first electrode layer of a first polarity directly on a first portion of the porous separator;
- (c) placing second electrode layer of the same polarity directly on a second portion of the porous separator;
- (d) placing at least one current collector layer directly on the first electrode layer;
- and
- (e) placing the second electrode layer on the one or more current collector layers on a side opposite to said first electrode layer.
A multilayer structure for use in a lithium battery comprising:
- (a) a porous separator;
- (b) a first electrode layer of a first polarity directly on a first portion of the porous separator;
- (c) a second electrode layer of the same polarity directly on a second portion of the porous separator;
- and
- (d) one or more current collector layers directly on the first electrode layer to make a separator/electrode stack, wherein
- (e) the second electrode layer is also on the one or more current collector layers on a side opposite to the first electrode layer.
