Abstract
Official abstract text for this publication.
A thin film lithium ion battery includes a cathode electrode, an anode electrode, and a solid electrolyte layer. The solid electrolyte layer is sandwiched between the cathode electrode and the anode electrode. At least one of the cathode electrode and the anode electrode includes a current collector. The current collector is a carbon nanotube layer consisting of a plurality of carbon nanotubes.
First claim
Opening claim text (preview).
What is claimed is: 1. A thin film lithium ion battery comprising at least one battery cell, the at least one battery cell comprising: a cathode electrode comprising a cathode material layer and a carbon nanotube layer attached on a surface of the cathode material layer, the cathode material layer and the carbon nanotube layer are two separate layers, the cathode material layer comprising a first plurality of carbon nanotubes entangled with each other and cathode active material particles wrapped by the first plurality of carbon nanotubes, wherein the cathode material layer consists of the plurality of cathode active material particles and the first plurality of carbon nanotubes; the carbon nanotube layer consisting of a second plurality of carbon nanotubes uncoated with other material, and the second plurality of carbon nanotubes uniformly distributed and substantially aligned along a same direction; an anode electrode; and a solid electrolyte layer sandwiched between the cathode electrode and the anode electrode.
