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.
Claims81
A method of forming an electrochemical cell, the method comprising contacting a negative pole layer and a positive pole layer one with the other or with an optional layer interposed therebetween, said pole layers and said optional layer being selected so as to self-form an interfacial separator layer between said pole layers upon said contacting.
A method of forming an electrochemical cell, the method comprising
- (a) printing a layer of positive pole powder onto a first substrate;
- (b) printing a layer of electrolyte on said positive pole layer, wherein said electrolyte comprises a self-forming separator layer ingredient;
- (c) printing a layer of negative pole powder onto a second substrate;
- (d) printing a layer of electrolyte on said negative pole layer, wherein said electrolyte comprises a self-forming separator layer ingredient;
- and
- (e) contacting said first substrate and said second substrate readily facilitating interaction between said self-forming separator layer ingredients in said positive pole layer and said negative pole layer to self form an interfacial separator layer between said negative pole layer and said positive pole layer.
A method of forming an electrochemical cell, the method comprising
- (a) printing a layer of positive pole powder onto a first substrate;
- (b) printing a layer of electrolyte on said positive pole layer, wherein said electrolyte comprises a self-forming separator layer ingredient;
- (c) printing a layer of negative pole powder onto a second substrate;
- (d) printing a layer of electrolyte on said negative pole layer, wherein said electrolyte comprises a self-forming separator layer ingredient;
- and
- (e) contacting said first substrate and said second substrate with a thin layer interposed between said positive pole layer and said negative pole layer, wherein said thin layer comprises a self-forming separator layer ingredient, readily facilitating interaction between said self-forming separator layer ingredients in said positive pole layer and said negative pole layer with said self-forming separator layer ingredient in said thin layer to self-form an interfacial separator layer between said negative pole layer and said positive pole layer.
An electrochemical cell comprising a negative pole layer, a positive pole layer and an interfacial separator layer interposed therebetween, said negative pole layer and said positive pole layer are selected so as to self-form said interfacial separator layer upon contacting one with the other or with an optional layer interposed therebetween.
