General description

The bio-sourced high surface area (1155 ± 69 m2/g) single layer sheets graphene for anode has an extremely high pore volume, enabling maximum energy power and density, as well as fast charging and no degradation over thousands of cycles.
The capacity of our anode after charging at 10 C ( minutes) is similar to graphite capacity at a charge rate of 0.1 C (i.e. 10 hours charging time). It can charge in a few minutes instead of hours, and showed a 5X increase in capacity at 0.1C vs. graphite anode (standard).
Our bio-sourced graphene is manufactured through an unique environmentally friendly non-oxidizing process that involves plant-based raw materials.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to enabling category of greener alternatives, and has been enhanced for energy efficiency. Click here for more information.

Application

It is effective at providing barrier properties, transport, electrical and thermal conductivity. The alpha grade graphene is shown to improve mechanical properties such as stiffness, strength, surface hardness and hydrophobicity.
Due to its superior properties, the alpha grade graphene have applications in:
1. Additives for light weight composites which require high specific strengths
2. Transparent, flexible and conductive applications unique to Photo Voltaic Solar cells
3. Oxidation-resistant anti-corrosion coatings
4. Ultra-filtration and separation barriers
5. Anode and cathode materials for lithium-ion batteries;
6. Conductive coatings for battery electrodes
7. Electrically conductive inks got printed electronics
8. Additive for super-strong, hydrophobic concrete
9. Electronic and optoelectronic devices
