Abstract
A method of forming an electrochemical cell is disclosed. The method comprises contacting a negative pole layer and a positive pole layer one with the other or with an optional layer interposed therebetween. The pole layers and the optional layer therebetween are selected so as to self-form an interfacial separator layer between the pole layers upon such contacting.
Claims91
A method of forming an electrochemical cell, the method comprising contacting a negative pole layer and a positive pole layer one with the other, wherein contacting causes components in electrolyte solution in negative pole layer and components in electrolyte solution in positive pole layer to interact and/or react with each other and self-form an interfacial separator layer within an electrolyte layer between said negative and positive poles.
An electrochemical cell comprising:
- a negative pole layer;
- a positive pole layer;
- and
- an integral and in-situ formed interfacial separator layer interposed therebetween within an electrolyte layer, wherein said integral and in-situ formed interfacial separator layer is comprised of interaction and/or reaction products of components in electrolyte solution in negative pole layer and components in electrolyte solution in positive pole layer and wherein there is no separately added separator.
A method of forming an electrochemical cell, the method comprising contacting a negative pole layer to a first side of a thin layer, the thin layer having a first side and an opposing second side, contacting a positive pole layer to the second side of the thin layer, wherein contacting causes electrolyte solution in negative pole layer, electrolyte solution in positive pole layer, and electrolyte solution in the thin layer to self-form a first interfacial separator layer within an electrolyte layer between said negative pole and said first side of said thin layer and to self-form a second interfacial separator layer within an electrolyte layer between said positive pole and said second side of said thin layer.
An electrochemical cell comprising:
- a negative pole layer including a first electrolyte solution;
- a positive pole layer including a second electrolyte solution;
- a thin layer having a first side and an opposing second side, said thin layer interposed between said negative and positive pole layers, wherein said first side of said thin layer is adjacent to said negative pole layer and said second side of said thin layer is adjacent to said positive pole layer;
- an integral first interfacial separator layer within an electrolyte layer between said negative pole and said first side of said thin layer;
- and
- an integral second interfacial separator layer within an electrolyte layer between said positive pole and said second side of said thin layer, wherein said first and second interfacial separator layers were formed in-situ.
A method of forming an electrochemical cell, the method comprising inserting a thin layer solution between a negative pole layer and a positive pole layer, such that interaction and/or reaction between components in the thin layer, components in the electrolyte solution in the negative pole layer, and components in the electrolyte solution in the positive pole layer self-form an interfacial separator layer.
