Increased reliability and charge speed of storage device


Any electric storage device has metallic current taps. They are actually aluminum and copper foils. The thickness of the current collector foil is determined by the maximum current of the electrical storage device. The main drawback of the metallic foil used in an electrical storage device is the oxide film on its surface.
This oxide film protects the metal from corrosion, but also creates insurmountable obstacles for electrical storage because:
So far no battery or supercapacitor manufacturer has been able to produce a current collector without the drawbacks mentioned above.
We propose to replace existing technologies for current collector manufacture with high-vacuum deposition technology.
Only in a vacuum can current collectors be manufactured without an oxide layer. This is done by replacing it with a chemically resistant and durable carbon coating with low contact resistance.

The protective carbon coating
The separator
The active carbon layer
Step 1
- The final result of the project is the production of industrial mass-production equipment, allowing the low-cost application of different carbon coatings (i.e. current collectors, active electrodes) onto roll materials (copper, aluminum foil, etc.).
The project duration is about 19 months:
- In the first 7 months experimental but already working industrial equipment will be produced.
- A further 12 months will be required for testing current collector samples with potential customers and to create a new, updated version of the equipment that is completely ready for commercial mass-production.
- Further, it will be possible to produce industrial equipment in any quantities (2, 10, 100 pieces per year). It all depends on the investor’s desire and the availability of funds.
Step 2
- Using the first industrial plant the following deposition technologies can be further perfected:
- Dense carbon coating that protects the metal from chemical corrosion (the current collector or metal electrode).
- Porous coating (active electrode).
- Separator.
Step 3
- The current collector with its dense carbon coating is thus the first step to implement in the overall business plan for the following reasons:
- This is the first coating, onto which the porous coating (the active electrode) will further be applied. And only after that will the separator be deposited onto the porous coating.
- The second step will be the deposition of the active high-porous electrode onto the current collector.
- The third step is the deposition of the separator.
