Abstract
Features for rechargeable lithium ion batteries, the batteries optionally employing vertically aligned carbon nanotube scaffolding, are described. Methods of manufacture and a solid polymer electrolyte are described for 3-dimensional battery architectures using the vertically aligned carbon nanotubes. Poly(ethylene)oxide bis(azide) and graphene poly(lactic acid) composite coatings are also described for use in such batteries or others.
Claims9
A method of electrochemical cell layer manufacture, the method comprising:
- forming an anode comprising a first current collector supporting anode carbon nanotubes, wherein the anode carbon nanotubes extend vertically from the first current collector in a direction perpendicular to a plane formed by the first current collector, and wherein the anode carbon nanotubes have an anode active material deposited thereon;
- forming a cathode comprising a second current collector supporting cathode carbon nanotubes, wherein the cathode carbon nanotubes extend vertically from the second current collector in a direction perpendicular to a plane formed by the second current collector, and wherein the cathode carbon nanotubes have a cathode active material deposited thereon;
- forming a solid polymer insulator configured to closely fit between the first and second current collectors;
- and
- assembling the first current collector, second current collector, and solid polymer insulator into a close-fit relationship to form a planar surface, and
- wherein the solid polymer insulator only separates the first and second current collectors.
