SuperCapacitor Materials Ltd has developed new electrolytes providing capacitance values over 100 times those of conventional electrolytes.
Our electrolytes make possible supercapacitors with greatly increased energy storage capabilities that can surpass conventional batteries. SuperCapacitor Materials Ltd can now assist potential commercial partners to develop a new generation of supercapacitors.
The energy density of a supercapacitor depends on the properties and effective surface area of the electrodes and the properties of the electrolyte.
- High charge and discharge rates
Wide range of operating temperatures
Long life cycles
- Low energy densities of approximately 3 – 7 WHr / Kg
SuperCapacitor Materials Ltd has researched and developed new, crosslinked gel electrolytes1 exhibiting measured capacitance values over 100 times those of conventional electrolytes2
These electrolytes are compatible with all materials used in normal production electrodes. They make possible supercapacitors with greatly enhanced specific energy storage capacities. We believe the combination of existing electrodes and our new electrolytes have the potential to create supercapacitors that have energy storage capacities which can approach or exceed existing battery systems.

Rolls-Royce links up with UK-based Superdielectrics to explore potential of very high energy storage technology
19 March 2018
Rolls-Royce has signed a collaboration agreement with UK-based technology start-up Superdielectrics Ltd to explore the potential of using polymers with recently discovered remarkable properties to create next generation high energy storage technology.
The agreement will see Rolls-Royce combine its world-class material science and technical expertise with Superdielectrics’ novel hydrophilic polymers that have been shown by Superdielectrics Ltd, in partnership with researchers from the Universities of Bristol and Surrey, to have potentially outstanding energy storage properties.
Dr. Dave Smith, Director of Central Technology, Rolls-Royce, said: “We are very pleased to be working with Superdielectrics Ltd at a time of rapidly-evolving developments in the energy storage industry. We bring deep experience of materials technology and advanced applications that require high energy storage capabilities with controllable rates of recovery.
We believe that electrification will play an increasingly important role in many of our markets over the coming years and by working with partners on potential new technologies for energy storage we can ensure that Rolls-Royce is well positioned to take advantage of new developments.”
Jim Heathcote CEO of Superdielectrics Ltd, said: “We are delighted to be working with Rolls-Royce in the global race to develop advanced energy storage systems. This agreement gives us access to their unparalleled scientific and technical expertise. I hope this agreement will ultimately create new jobs and business opportunities in the UK.”
Working with researchers from the Universities of Bristol and Surrey, Superdielectrics Ltd has been developing hydrophilic materials, similar to those originally designed for soft contact lenses, to increase the electricity storage capabilities of capacitors, which store electricity by creating electrostatic fields. These potentially exciting dielectric polymers may provide an opportunity to create capacitors that are able to rival – and even exceed – the storage capacity of traditional rechargeable batteries. The resulting supercapacitors may also be able to charge much faster than existing lithium-ion batteries. The exact terms of the agreement between Rolls-Royce and Superdielectrics remain confidential.

Alternative to traditional batteries moves a step closer to reality after exciting progress in supercapacitor technology
26th February 2018
Lithium-ion batteries could be under threat after the development of polymer materials by the Universities of Surrey and Bristol, along with Superdielectrics Ltd, that could challenge the dominance of these traditional batteries.
Only one year ago, the partners announced scientific results for novel polymer materials that have dielectric properties 1,000 to 10,000 times greater than existing electrolytes (electrical conductors). These stunning scientific findings have now been converted into ‘device’ scale technical demonstrations.
Researchers from the universities achieved practical capacitance values of up to 4F/cm2 on smooth low-cost metal foil electrodes. Existing supercapacitors on the market typically reach 0.3F/cm2 depending upon complex extended surface electrodes.
More significantly, the researchers managed to achieve results of 11-20F/cm2 when the polymers were used with specially treated stainless-steel electrodes – the details of which are being kept private pending a patent application.
If these values of capacitance can be achieved in production, it could potentially see supercapacitors achieving energy densities of up to 180 WHr/kg – greater than lithium ion batteries.
Supercapacitors store energy using electrodes and electrolytes and both charge and deliver energy quickly – conventional batteries perform the same task in a much slower, more sustained way. Supercapacitors have the ability to charge and discharge rapidly over very large numbers of cycles. However, because existing supercapacitors have poor energy density per kilogramme (currently around one twentieth of existing battery technology), they have been unable to compete with conventional battery energy storage. Even with this restriction, supercapacitor buses are already being used in China, but the current technology means that they need to stop to be recharged frequently (i.e. at almost every bus-stop).
The team of scientists have been able to test the new materials in two ways:
- By using small single layer cells charged to 1.5 volts for two to five minutes and then run demonstration devices, including a small fan.
- By using a three-cell series stack that is able to be rapidly charged to five volts and operate an LED.
The University of Bristol is going much further by producing a complex series-parallel cell structure in which both the total capacitance and operating voltage can be separately controlled.
Based on these impressive results, Superdielectrics Ltd, the company behind this technology, is now looking to build a research and low volume production centre. If successful in production, the material could not only be used as a battery for future mobile devices, but could also be used in refuelling stations for electric cars.
Dr Brendan Howlin, Senior Lecturer in Computational Chemistry at the University of Surrey, said: “These results are extremely exciting and it is hard to believe that we have come so far in such a short time. We could be at the start of a new chapter in the technology of low cost electrical energy storage that could shape the future of industry and society for many years to come.”
Dr Donald Highgate, Director of Research for Superdielectrics Ltd and alumnus of the University of Surrey, said: “These exciting results are of particular satisfaction to me because they build upon my work in hydrophilic polymers that has been a major part of my professional life; beginning in the later 1970s with extended wear soft contact lenses, and leading in the period 1990 to 2009, to fuel cells and electrolysers of exceptional efficiency.
“The present work, if it can be translated into production, promises to make rapid charging possible for electric vehicles, as well as offering a much-needed low cost method of storing the transient output from renewable energy systems. Wind, wave and solar energy is available but it is intermittent and, without storage, cannot be relied upon to meet our energy needs. This new work would transform the energy system which underpins our entire way of life – it is the necessary development before we and our children can have a genuinely sustainable, environmentally safe energy supply.”
Dr Ian Hamerton, Reader in Polymers and Composite Materials from the Department of Aerospace Engineering at the University of Bristol, commented: “Following the unveiling of the preliminary results at the first press conference just 14 months ago, the team has worked hard to increase the storage capability of these innovative materials still further. Our foremost challenge is now to translate these scientific findings into robust engineered devices and unlock their revolutionary potential.”
Scientific breakthrough reveals unprecedented alternative to battery power storage
6th December 2016
- Major scientific breakthrough research has discovered new materials offering an alternative to battery power proven to be between 1,000-10,000 times more powerful than the existing battery alternative – a supercapacitor.
- The new technology is believed to have the potential for electric cars to travel to similar distances as petrol cars without the need to stop for lengthy re-charging breaks of between 6-8 hours, and instead re-charge fully in the time it takes to fill a regular car with petrol.
- The scientific findings made by Augmented Optics Ltd and its wholly owned subsidiary Supercapacitor Materials Ltd with the University of Surrey and University of Bristol have produced a safer, faster charging, more efficient and greener alternative to battery power and supercapacitor abilities as we currently know them.
Ground-breaking research from the University of Surrey and Augmented Optics Ltd., in collaboration with the University of Bristol, has developed potentially transformational technology which could revolutionise the capabilities of appliances that have previously relied on battery power to work.
This development by Augmented Optics Ltd., could translate into very high energy density super-capacitors making it possible to recharge your mobile phone, laptop or other mobile devices in just a few seconds.
The technology could have a seismic impact across a number of industries, including transport, aerospace, energy generation, and household applications such as mobile phones, flat screen electronic devices, and biosensors. It could also revolutionise electric cars, allowing the possibility for them to recharge as quickly as it takes for a regular non-electric car to refuel with petrol – a process that currently takes approximately 6-8 hours to recharge. Imagine, instead of an electric car being limited to a drive from London to Brighton, the new technology could allow the electric car to travel from London to Edinburgh without the need to recharge, but when it did recharge for this operation to take just a few minutes to perform.
Supercapacitor buses are already being used in China, but they have a very limited range whereas this technology could allow them to travel a lot further between recharges. Instead of recharging every 2-3 stops this technology could mean they only need to recharge every 20-30 stops and that will only take a few seconds.
Elon Musk, of Tesla and SpaceX, has previously stated his belief that supercapacitors are likely to be the technology for future electric air transportation. We believe that the present scientific advance could make that vision a reality.
The technology was adapted from the principles used to make soft contact lenses, which Dr Donald Highgate (of Augmented Optics, and an alumnus of the University of Surrey) developed following his postgraduate studies at Surrey 40 years ago. Supercapacitors, an alternative power source to batteries, store energy using electrodes and electrolytes and both charge and deliver energy quickly, unlike conventional batteries which do so in a much slower, more sustained way. Supercapacitors have the ability to charge and discharge rapidly over very large numbers of cycles. However, because of their poor energy density per kilogramme (approximately just one twentieth of existing battery technology), they have, until now, been unable to compete with conventional battery energy storage in many applications.
Dr Brendan Howlin of the University of Surrey, explained: “There is a global search for new energy storage technology and this new ultra capacity supercapacitor has the potential to open the door to unimaginably exciting developments.”
The ground-breaking research programme was conducted by researchers at the University of Surrey’s Department of Chemistry where the project was initiated by Dr Donald Highgate of Augmented Optics Ltd. The research team was co-led by the Principal Investigators Dr Ian Hamerton and Dr Brendan Howlin. Dr Hamerton continues to collaborate on the project in his new post at the University of Bristol, where the electrochemical testing to trial the research findings was carried out by fellow University of Bristol academic – David Fermin, Professor of Electrochemistry in the School of Chemistry.
Dr Ian Hamerton, Reader in Polymers and Composite Materials from the Department of Aerospace Engineering, University of Bristol said: “While this research has potentially opened the route to very high density supercapacitors, these *polymers have many other possible uses in which tough, flexible conducting materials are desirable, including bioelectronics, sensors, wearable electronics, and advanced optics. We believe that this is an extremely exciting and potentially game changing development.”
*the materials are based on large organic molecules composed of many repeated sub-units and bonded together to form a 3-dimensional network.
Jim Heathcote, Chief Executive of both Augmented Optics Ltd and Supercapacitor Materials Ltd, said: “It is a privilege to work with the teams from the University of Surrey and the University of Bristol. The test results from the new polymers suggest that extremely high energy density supercapacitors could be constructed in the very near future. We are now actively seeking commercial partners in order to supply our polymers and offer assistance to build these ultra high energy density storage devices.”
