Abstract
The present disclosure is directed to methods for production of composites of carbon nanotubes and electrode active material from liquid dispersions. 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.
Claims10
A method of making a self-standing electrode, the method comprising:
- providing a liquid dispersion comprising carbon nanotubes or carbon fibers, and a liquid medium;
- wet-depositing the carbon nanotubes or the carbon fibers from the liquid dispersion to a moving substrate, which is pre-deposited with an electrode active material, to form a composite comprising both the carbon nanotubes or the carbon fibers and the electrode active material;
- and
- removing the composite from the substrate to form a self-standing electrode,
- wherein the electrode active material is not mixed with carbon nanotubes or carbon fibers prior to wet-depositing the carbon nanotubes or the carbon fibers from the liquid dispersion to the moving substrate.
