In the rapidly evolving landscape of energy storage solutions, ultracapacitors emerge as standout performers. Their ability to rapidly charge and discharge, coupled with a prolonged cycle life and impressive power density, positions them as a formidable choice in applications requiring burst mode power delivery. At enyGy®, we lead the charge in material innovation, harnessing the power of graphene to significantly enhance the energy density of ultracapacitors.
Ultracapacitors are rapid energy storage systems that store energy electrostatically. Power density refers to how quickly they can charge and discharge, while energy density measures the amount of energy storable within a specific volume (volumetric energy density). While ultracapacitors excel in instantaneous power delivery, they traditionally lag behind in energy density.
At enyGy, our commitment to advancing ultracapacitor technology is epitomized by our pioneering use of graphene. Graphene boasts remarkable electrical and thermal conductivity and a vast surface area, making it the most electrically conductive material known. These properties make graphene ideal for enhancing the volumetric energy density of ultracapacitors.
Through rigorous research and development, enyGy has leveraged proprietary graphene technology to significantly boost the performance of ultracapacitor energy storage capabilities, surpassing current limitations.
In the typical construction of an ultracapacitor, activated carbon materials are used to form an electrode film. This film is what stores the energy and gives an ultracapacitor a higher energy density than that of traditional capacitors. By combining enyGy’s technological nanomaterial innovations with graphene’s high electrical conductivity and large surface area, enyGy has achieved up to double the energy density of leading ultracapacitors on the market today.
This advancement hinges on enyGy’s ability to preserve graphene’s outstanding properties - high electrical and thermal conductivity, and a large surface area - by finely controlling its structure and chemistry at nanoscale. Implementing graphene in ultracapacitor electrode films poses significant challenges, which enyGy has successfully overcome.
“A unique nano-engineering strategy has been developed to manipulate the individual graphene sheets and to control the inter-sheet spacing and interactions down in sub-nanometer scale. This achieves compact energy storage capability by graphene-based electrode films” explained Professor Dan Li, enyGy affiliate.
Looking forward, enyGy aims to expand into Hybrid Energy Storage Systems (HESS), which combine two or more energy storage technologies to outperform any single-component energy storage device (such as batteries, flywheels, ultracapacitors, and fuel cells).
Integrating ultracapacitors with conventional batteries or other energy storage mediums presents a synergistic approach to overcoming inherent limitations. EnyGy advocates for hybrid energy storage systems, combining the rapid charge-discharge capabilities of ultracapacitors with the extended energy storage capacity of batteries, optimizing performance across diverse applications.
"The future of energy storage lies not in singular solutions but in harmonious blends of technologies. Hybrid systems represent the convergence of innovation, optimizing performance, and sustainability," said Mr. Wiehann de Klerk, CEO of enyGy.
EnyGy considers innovation not only as the creation of new technology but also as how that new technology can leverage the strengths of and integrate with existing technologies, systems, and processes. One such application of this innovative amalgamation is hybrid technology.
Ultracapacitor technology holds transformative potential, offering unrivalled rapid charge-discharge capabilities, extended cycle life, and impressive power density. However, challenges such as energy density limitations have tempered its universal adoption. At enyGy, we remain steadfast, leveraging groundbreaking material innovations like graphene to overcome these challenges. Through our relentless pursuit of excellence in material science, we envision a future where ultracapacitors redefine energy storage paradigms, ushering in a sustainable and efficient energy landscape. Join us on this exhilarating journey toward innovation and sustainability.
