Abstract
Abstract An electrolytic cell, such as a rechargeable lithium battery, fabricated in a carbon dioxide atmosphere, having a lithium carbonate passivating layer associated with a lithium ion source electrode and an electrolyte. Fabrication of an electrolytic cell containing an acrylic polymer paste cathode, anode and electrolyte increases the efficiency of the polymer initiator and facilitates free radical chain growth polymerizations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
An electrolytic process associated with fabrication of an electrolytic cell comprising the steps of: inserting sub components of an electrolytic cell into a chamber having an atmosphere, at least one of the sub components includes a lithium source anode, an electrolyte and a cathode wherein at least one of the electrolyte, anode or cathode is acrylic based, displacing the atmosphere within the chamber with carbon dioxide, displacing oxygen, which may be in the at least one of the acrylic based anode, cathode or electrolyte, with carbon dioxide to, in turn, facilitate a free-radical chain growth reaction, fabricating the sub components into components for use in the electrolytic cell, and assembling the fabricated components into an electrolytic cell.
Claim 2
Dependent Claim
117 words
An electrolytic process associated with fabrication of an electrolytic cell comprising the steps of: inserting sub components of an electrolytic cell into a chamber having an atmosphere, at least one of the sub components includes a lithium source anode, an electrolyte and a cathode wherein at least one of the electrolyte, anode or cathode is acrylic based, displacing the atmosphere within the chamber with carbon dioxide, displacing oxygen, which may be in the at least one of the acrylic based anode, cathode or electrolyte, with carbon dioxide to, in turn, facilitate a free-radical chain growth reaction, fabricating the sub components into components for use in the electrolytic cell, and assembling the fabricated components into an electrolytic cell.
Claim 3
Dependent Claim
40 words
The process according to claim 1, further including the step of restricting penetration of acids generated within the completely fabricated electrolytic cell, during aging and operation, through the passive layer, and, in turn, into contact with the lithium source anode.
Claim 4
Dependent Claim
40 words
The process according to claim 1, wherein the step of displacing the atmosphere within the chamber with carbon dioxide further comprises the step of: saturating the at least one of the acrylic based anode, cathode or electrolyte with carbon dioxide.
Claim 5
Dependent Claim
41 words
The process according to claim 1 further comprising the step of maintaining a predetermined amount of carbon dioxide within the fully fabricated electrolytic cell to, in turn, prevent reabsorption of oxygen within at least one of the electrolyte, anode and cathode.
Claim 6
Dependent Claim
53 words
The process according to claim 1 wherein the sub components further include a cathode paste; the step of fabricating the components includes the steps of: applying the cathode paste onto a substrate; at least partially curing the cathode paste; applying the electrolyte over the cathode paste; and at least partially curing the electrolyte.
Claim 7
Dependent Claim
38 words
The process according to claim 5 wherein the step of assembling the fabricated sub components further comprises the step of associating an anode with the electrolyte and cathode, to, in turn, result in a fully assembled electrolytic cell.
Claim 8
Dependent Claim
53 words
The process according to claim 1 wherein the sub components further include an anode paste; the step of fabricating the components includes the steps of: applying the anode paste onto a substrate; at least partially curing the anode paste; applying the electrolyte over the anode paste; and at least partially curing the electrolyte.
Claim 9
Dependent Claim
38 words
The process according to claim 7 wherein the step of assembling the fabricated sub components further comprises the step of associating a cathode with the electrolyte and anode, to, in turn, result in a fully assembled electrolytic cell.
