Abstract
Official abstract text for this publication.
An electrode structure for use in a battery cell includes: a current collector layer having a current collector surface; a free-standing electrode layer having an electrode surface that faces the current collector surface; and an interlayer arranged between the current collector surface and the electrode surface. The interlayer includes an electrically conducting material.
First claim
Opening claim text (preview).
1 : An electrode structure for use in a battery cell, the electrode structure comprising: a current collector layer having a current collector surface; a free-standing electrode layer having an electrode surface that faces the current collector surface; and an interlayer arranged between the current collector surface and the electrode surface, the interlayer comprising an electrically conducting material. 2 : The electrode structure of claim 1 , wherein the interlayer and/or electrode is deformable. 3 : The electrode structure of claim 2 , wherein the interlayer is deformable. 4 : The electrode structure of claim 1 , wherein the electrode is a sintered electrode. 5 : The electrode structure of claim 4 , wherein the electrode comprises a lithium metal oxide. 6 : The electrode structure of claim 1 , wherein the interlayer comprises carbon. 7 : The electrode structure of claim 6 , wherein the interlayer comprises graphite. 8 : The electrode structure of claim 1 , wherein the electrode is separable from the interlayer. 9 : The electrode structure of claim 1 , wherein the interlayer is an adhesive layer that adheres the electrode to the current collector. 10 : The electrode structure of claim 9 , wherein the interlayer comprises a binder. 11 : The electrode structure of claim 10 , wherein the binder is a thermoplastic material. 12 : The electrode structure of claim 1 , wherein the current collector comprises a further current collector surface opposite the current collector surface, and the electrode structure comprises: a further free-standing electrode layer having a further electrode surface that faces the further current collector surface; and a further interlayer arranged between the further current collector surface and the further electrode surface, the further interlayer comprising an electrically conducting material. 13 : A battery cell incorporating the electrode structure of claim 1 . 14 : A method of making an electrode structure for use in a battery cell, the method comprising: providing a current collector layer having a current collector surface; providing a free-standing electrode having an electrode surface; arranging an electrically-conducting interlayer between the current collector surface and the electrode surface. 15 : The method of claim 14 , comprising arranging the electrically-conducting interlayer on the current collector surface, and arranging the free-standing electrode on the electrically-conducting interlayer. 16 : The method of claim 14 , wherein the current collector comprises a further current collector surface opposite the current collector surface, and the method further comprises: providing a further free-standing electrode having a further electrode surface; and arranging a further electrically-conducting interlayer between the further current collector surface and the further electrode surface.
