Superdielectrics Ltd: Insights
Superdielectrics LTD is in the process of developing a supercapacitor that can charge and discharge at record speeds. This technology is thought to be ideal for electric cars and would be critical in the widespread commercial use. They would be an ideal replacement of batteries as they will be cheaper to produce, produce large amounts of energy, and charge at record speeds.
Superdielectrics LTD Presents Research Results
- In 2018, for a period of 14 months, researchers from Bristol and Surrey universities were testing the use of Superdielectrics' supercapacitors in every-day items.
- This research has drawn various conclusions that have been presented as part of this research.
A Supercapacitor is Easy to Produce
- The materials used in making this supercapacitor are easily accessible such as water and the production process is cheap as no rare elements are in play.
- The main component of this system is water. This reduces the risk of a fire in comparison to traditional batteries.
- Additionally, the director of research at the company says that this discovery may have happened by accident.
- Conventional supercapacitors are expensive. This would be a bearable cost in terms of machinery use in a factory but would be costly for individual/personal use.
They Store Large Amounts of Electricity
- According to the CEO Jim Heathcote, the amounts of energy that can be stored in the supercapacitors is "remarkable."
- These small devices can power a fan or an LED for a couple of minutes. With continued work, these supercapacitors could reach an energy density of up to 180 watt-hours per kilogram. By this time, the best current amount is 10 watt-hours per kilogram.
- This capacitor shows values that are 1,000-10,000 times higher than in the aqueous electrolytes in other supercapacitors.
Reduction in the Charging Duration
- When considering the shortened charging time, the adoption of application in electric vehicles is highly plausible.
- The anxiety associated with electric vehicles is the charging time. If this is addressed, it will inevitably accelerate its adoption by the public.
- In terms of design, the soft contact lenses were discovered to be great at holding an electrostatic field. This technology allows the device to quickly charge and also quickly discharge.
Supercapacitors in EV Charging Still Underway
- Although polymer-based supercapacitors are emerging, they are still considered promising technology, still undergoing testing and experimentation.
- It is critical to ensure that power, lifetime, and cost is not compromised when determining its energy storage capacity.
- As far back as 2011, Elon Musk had stated that capacitors, not batteries, would be the source of energy for electric cars.
- It is clear that the use of supercapacitors in EVs are yet to be realized. They are not being used as the source of energy but as an important component in the current hybrid system.
- Although it would have a seismic effect on energy sources for electric vehicles, supercapacitors are not yet there.
Supercapacitors are the Best Option Yet
- A normal battery relies on a chemical reaction. Over time, these chemicals become weaker as they charge and discharge.
- Traditional batteries require some rare materials such as cobalt while supercapacitors do not.
- Traditional batteries are gradually improving in quality and efficiency each year, which shows that they will not be phased out by supercapacitors.
- If fossil fuels are no longer a source of energy, we will rely on renewable energy. For this reason, there will be a need to ensure access energy when there is limited solar/sun or wind exposure.
- In a 100% sustainable energy system, highly efficient supercapacitors will be a critical component.
Drawbacks of Supercapacitors in EV
- If a supercapacitor car is parked in one location for a long period of time (one month), it would lose most of its charge. For this reason, until this is resolved, the first cars may still require at least a small conventional battery to hold the charge.
- Major components of this technology are yet to be fully analyzed and understood. These include its scalability, cost, and sustainability.
