EnyGy, a Melbourne-based startup with its roots at Monash University and research by Prof. Dan Li and Dr. Yufei Wang, announced the launch of an ultracapacitor relying on the latest graphene technology.
More than seven years have been spent developing the nanomaterial that will be used in the enyCap and enyGcap ultracapacitors.
“Fundamentally, enyGcap provides increased energy storage capacity within the same package size, known as enhanced energy density, enabling the realisation of compact, fast energy storage,” said Wiehann de Klerk, CEO of EnyGy.
“The enyGcap ultracapacitor technology can be used for rapidly storing and discharging energy in various applications, including electric vehicles, renewable energy systems, and consumer electronics.
“For instance, ultracapacitor-based modules provide a valuable solution for improving tram regenerative braking systems with their swift charge and discharge abilities. This not only boosts performance but also reveals significant cost-saving opportunities,” he said.
“Incorporate our graphene technology into the equation, and you can realise up to double the cost savings, thanks to the heightened energy storage capacity.”
The product combines activated carbon electrodes with state-of-the-art electrolytes, delivering a remarkable 3V of power. The product is the first of its kind to utilise graphene technology and is currently undergoing trials. EnyGy worked with UL Solutions to obtain third-party, science-backed certification for the enyCap product line. Ultracapacitors also offers a wide range of operating temperatures, from -40°C to +65°C. The materials used are also easier to recycle than most common battery materials.
By early 2024, the enyCap – an electrical double layer capacitor (EDLC) meticulously made by interweaving activated carbon electrodes with a state-of-the-art electrolyte – will be unveiled. Then, by late 2024, EnyGy will unveil the enyGcap. These ultracapacitors boast energy densities that are up to double the energy capacity of prevailing activated carbon counterparts.
