Abstract
The present disclosure is directed to a method and apparatus for continuous production of composites of carbon nanotubes and electrode active material from decoupled sources. Composites thusly produced may be used as self-standing electrodes without binder or collector. Moreover, the method of the present disclosure may allow more cost-efficient production while simultaneously affording control over nanotube loading and composite thickness.
Claims20
A method of making a self-standing electrode, the method comprising:
- fluidizing an electrode active material;
- and
- co-depositing the fluidized electrode active material and single-walled carbon nanotubes onto a movable porous flexible substrate to form a self-standing electrode that is a composite of the electrode active material and the single-walled carbon nanotubes;
- and
- removing the self-standing electrode from the porous flexible substrate,
- wherein the self-standing electrode has a density of 0.75 g/cc to 2.28 g/cc., and
- wherein the self-standing electrode comprises 0.1% to 4% by weight carbon nanotubes.
