A UK start-up developing innovative and fast charge super capacitor based battery chargers for smartphones and associated devices is now ready to manufacture their products and is offering a manufacturing agreement. The company is looking for suppliers of materials for the super capacitors and, ideally, their preferred partner should also be able to manufacture the super capacitors, though the supplies and manufacturer could be two different companies.
The Oxfordshire, UK, based company was established in 2012 and is exploiting graphene/carbon nano-material technologies, which are being developed in-house. The battery chargers they are developing enable smartphones and other mobile devices with a USB port to be fully charged up in less than 5 minutes.
The company has successfully completed the feasibility phase and the product is currently at a working prototype stage. The company is offering a manufacturing agreement to partners who can supply them with the right materials and also help with manufacturing the super capacitors. They plan to launch the product to its end users at the end of 2015 or beginning of 2016. With this in mind, they are tentatively looking to hear from manufacturers of chargers for an exploratory conversation, but the exact details of the chargers are still under discussion.
The materials sought:
1. Graphene powder/carbon nano- tubes/activated carbon/other carbon nano-materials:
• Surface area - preferably targeting upwards of 1000- 2000m2/g
• Mezo-porosity contained within particles between 2 and 50nm
• Electrical conductivity - ideally targeting values close to aluminium metal.
2. Electronic grade/battery grade, electrically conductive aluminium foil in the absence of oxide layer (nickel or copper is interesting too):
10 microns to 25 microns thick, 50m+ roll; could be plasma treated or carbon coated – preferably uncoated – surface should promote good adherence of a carbon based coating and good electrical continuity/conductivity across the boundary.
3. Nano-porous polyethylene and polypropylene (polyolefin) barrier membrane:
• Super capacitor/battery grade
• 50-60% porosity.
4. Ionic electrolytes:
• Suitable for batteries and super capacitors
• Targeting operational voltages greater than 3.5V
• Targeting operational temperatures between -20oC and + 80oC
• Targeting low internal resistance < 10mΩ.
5. Electrically conducting binders and solvents that are suitable for producing inks for electrodes for batteries and super capacitors.
Companies working with this business will have the potential to get involved with a fast growing and large market sector with high earnings potential.
• Manufacturers supplying the materials will have an in-depth knowledge of their products and be at the cutting edge of technology in the battery/super capacitor arena
• Manufacturers of nano-materials will ideally be conversant with the Responsible Care initiative of the International Council of Chemical Associations and appropriate health, environment and safety directives
• Predicted monthly requirements at full scale manufacture:
- 1,700,000m aluminium foil
- 50t ink – 11t nano-material filler
- 124,000m2 barrier material
- 15,000l electrolyte.
Specific area of activity of the partner:
• Manufacturers of the materials mentioned in description, preferably those who can also manufacture the super capacitors.
A manufacturing agreement is offered.
