Current Collectors

Provide conduction of electrons from the positive and negative terminals and connect with the external circuits of the battery.

OUR TECHNOLOGY

What is a current collector?

Current Collectors are one of the most important components in a battery because these components are responsible to allow the flow of electrons between the negative and the positive terminals of the battery (electrodes) which directly influence the charge duration and the useful life of the cell.

Main Issues

Long processability time and expensive manufacturing process 

High degradation and severe oxidation issues

High contact resistance and poor addition

A NEW CURRENT COLLECTOR TECHNOLOGY

Dispenses of the use of toxic and polluting raw materials or thermal drying processes

OUR SOLUTION

Our proposal is to do it better….

GNN main goals for this new current collector technology involves the use of natural binders and nanomaterials to increase the surface area, reduce the contact resistance, improve the adherence and at the same time develop a more efficient and low-cost manufacturing process in order to make the battery industry more competitive and sustainable for applications like electric vehicles, mobile devices and energy storage systems of high electrical performance.

How we achieved that….

Our technology involves the use of carbon nanomaterials for the fabrication of the coating slurry that is apply by a revolutionary and fast deposition process that takes only 15 seconds and that is not dependent on toxic and pollutant raw materials. GNN chemistry and manufacturing process allows to have more control of the coating thickness, adherence quality and contact resistance of the slurry on the metal foil which is directly linked to the current collector properties.
