Batteries and Supercapacitors

Symmetric and asymmetric carbon-based:

The energy density of lead acid batteries is in the region of 33-40 Wh per kg. Our prototype all-carbon energy storage devices are now reaching over 60 Wh per kg, providing a space within the market for replacing lead acid with higher performing all carbon batteries. Asymmetric devices of aqueous system structured carbons provide well over 350 Wh per kg, presenting opportunities for the replacement of lithium ion batteries which supply between 125-250 Wh per kg. 

The cost structures associated with the relevant battery types are: lead acid $70-100 kWh, carbon-carbon symmetric devices $26 kWh, lithium ion $200-700 kWh, asymmetric structured carbon devices $75 kWh.

Advantages of carbon-based devices are therefore:

  •              Longer Life cycle
  •              Higher energy density for lower cost per kWh
  •              High power density
  •              Non-toxic production processes
  •              Easy end of life disposal
  •              Ease of manfacture/low waste stream production
  •              No legacy issues

We are currently working on carbon nanomaterials derived from seaweed, hemp bast waste, tyre reclamation and coal mining waste to create batteries and supercapacitors for a variety of applications.  We are actively seeking licensees or joint venture partners to put our range of batteries into production.  Please contact Gary at

Plans to commercialise our energy storage devices were announced by Rob in November 2018. You can see the announcement here.

Part of the plan is to support entrepreneurs in developing regions to set-up their own factories. You can get more information on our ideas here.
