Abstract
Electrodes and methods of forming electrodes are described herein. The electrode can be an electrode of an electrochemical cell or battery. The electrode includes a current collector and a film in electrical communication with the current collector. The film may include a carbon phase that holds the film together. The electrode further includes an electrode attachment substance that adheres the film to the current collector.
Claims21
An electrochemical cell comprising:
- an electrode comprising an active material;
- a separator;
- and
- a cell attachment substance to adhere the electrode to the separator, wherein the electrode comprises a hard carbon phase to hold the active material together.
1 more element
An electrochemical cell comprising:
- an electrode;
- a separator;
- and
- a cell attachment substance that adheres the electrode to the separator, wherein:
- the electrode comprises porosity and at least about 60 percent of the porosity is substantially free of the cell attachment substance;
- the electrode comprises an active material and a carbon phase holds the active material together, the carbon phase comprising hard carbon;
- and
- the active material comprises silicon particles distributed within the carbon phase.
