Innovative energy storage technology is revolutionising the way we are able to store and distribute renewable energy.
Capacitors are devices which store small amounts of current static energy, rather than traditional storage of energy which uses a chemical reaction.
Researchers have been looking to improve energy storage devices which would improve overall energy storage technology, one of these models being the use of sophisticated capacitor technology.
The many of the limits associated with battery storage and their declining credibility as storage products has lead to alternative energy markets predicting super capacitors to replace batteries entirely in the not too distant future.
So how does a super capacitor substantiate such a claim? Simply comparing the characteristics of battery and super capacitor technology proves the superiority of super capacitors as the future of energy storage.
Batteries vs Super Capacitors
The Battery
- Batteries need charging which may be seen as an inconvenience
- Charging takes a lot of time as batteries often require hours before charged completely.
- Modern day batteries require maintenance – wear and tear is an inevitable part of owning a battery as they have an electric-chemical nature with a set life cycle.
- Batteries utilise natural resources and have a higher impact on the environment.
The Super Capacitor
- A super capacitor can be re-charged indefinitely and don’t have a battery life issue.
- A super capacitor doesn’t need end of charge cessation, it detects and responds as needed as it reaches the charging threshold level. It draws the charge as its needed which eliminates the risk of over-charging.
- There is no wear and tear when it comes to super capacitors and the age of the device doesn’t play a part in its functioning. No replacement is needed.
- The device is also easier on the environment as it only uses the energy needed and less natural resources are required.
Research has received more funding to address limits facing super capacitors and progress is being made to improve the technology further.
Limitations of the Super Capacitor:
- Relatively lower energy
- Lower cell volts
- Higher costs per watt
With enough funding such limits can be worked upon, with tests even being conducted to improve functionality of the electric car in conjunction with the use of super capacitors.
Advancements in research will most likely allow for super capacitors to lead the way in all aspects of energy storage from vehicle technology to cell phones, as we move away from fuel dependence and towards renewables.
