Development of Advanced Ultracapacitor Electrodes (25526)

Ioxus, Inc.


Ultracapacitor devices offer the potential to revolutionize hybrid- or all-electric mass-transit buses, fleet vehicles, long-haul trucks and other heavy-duty transportation vehicles via their ability to rapidly and repetitively store and discharge the large amounts of electrical energy transiently used in these systems. Although ultracapacitor designs have improved markedly in recent years, these devices still are not capable of storing sufficient electrical energy to enable their widespread use in hybrid- or all-electric transportation systems. Ioxus, Inc., an Oneonta, NY-based manufacturer of industry-leading ultracapacitors, will employ graphene from several graphene powder synthesis experts to develop ultracapacitors with the increased energy densities needed for transportation systems.

Project Description

Ioxus will develop advanced ultracapacitor electrodes containing graphene, a compound related to the activated carbon already used to produce ultracapacitor electrodes, but with properties that will increase the performance of these electrodes. Graphene materials will be incorporated into ultracapacitor electrodes under conditions that improve its effects on the electrode’s energy storage capabilities, while preserving the necessary economics of ultracapacitor manufacturing. The goal is to achieve a cost-effective 2X or greater increase in the energy storage capacity of the ultracapacitors built using graphene-based electrodes, which is sufficient to markedly increase the applicability of ultracapacitors to hybrid- or all-electric transportation systems.


By fostering faster adoption of electric vehicles/hybrid electric vehicles, the subject technology could provide large reductions in petroleum consumption, with proportionate reductions in production of greenhouse gases and air pollutants, and could create many New York State jobs.
