BREAKTHROUGH TECHNOLOGY THAT HAS THE POTENTIAL TO TRANSFORM ENERGY STORAGE LANDSCAPE

The search for a better battery…

Lithium ion batteries (LIBs) are very popular in portable electronics because of their high energy density and small memory effect. They play an important role in the progress of electric vehicles, power tools, military and aerospace applications. However, like any other any storage system, LIBs still suffer from many shortcomings. While normal electronic devices have seen very rapid progress following Moore’s law, batteries have advanced only slightly. Our goal at Nanotech Energy is to minimize that gap by developing a new generation of batteries with performance features far exceeding those currently available in the market.

Why graphene for energy storage?

Graphene is a single layer of graphite; an array of carbon atoms arranged in a hexagonal honeycomb lattice. .It’s hard to describe the properties of graphene without a heavy dependence on superlatives. At just one atom thick, it’s a million times thinner than a human hair, 200 times stronger than steel. It’s a better conductor of electricity than copper. In fact, it’s better than anything at conducting heat and electricity. It’s extremely flexible–bendable and stretchable–impermeable to water, transparent, completely organic, affordable…and that’s just for starters. Graphene is expected to enable energy storage devices with several new features that do not exist in the current technology. Nanotech Energy is working on converting this dream into a reality.

GRAPHENE SUPERBATTERYTM FEATURES

  • GSB provides energy at a fraction of the cost of the current lithium ion battery technology
  • GSB offers unmatched capacity with the potential to extend the run time for electronic devices.
  • GSB promises 2 to 5 times longer cycle and calendar life
  • Introduced with a new separator, GSB shows improved safety and fire rating
  • GSB can be operated over a wide temperature range, enabling cold starting in extreme weather
  • GSB offers fast charging capability thanks to the reduced diffusion distance of nanomaterials
  • Another interesting feature is the ability to deliver high power on demand due to reduced cell resistance

The power to change
the world

Nanotech Scientific Board Members, Richard Kaner, PhD, and Maher El-Kady, PhD, have developed a scalable way to create graphene supercapacitors. Here, they explain the wonders of graphene and their game-changing discovery.

How we make graphene

To extract graphene from graphite, Nanotech Energy uses simple chemical compounds that insert oxygen atoms between the layers of graphene, converting it to graphite oxide which falls apart in water forming individual graphene oxide sheets. These sheets can be converted back to graphene using proprietary chemical, hydrothermal and photothermal methods.
