As one of the most advancing sustainable energy, solar energy is highly anticipated against the background of the worsening environment and energy shortage. But its development meets several obstacles, one of which is storage. It is a technological problem to store solar energy and apply it when needed. 

Thanks to the ultracapacitor, whose development has promoted the capacity to conserve energy, allowing the industry to progress.

If you wonder what the role of the ultracapacitor is in advancing solar energy, this passage can offer you some hints.

Get to Know the Solar Energy and Its Storage

solar energy is radiation from the sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly more than the world’s current and anticipated energy requirements. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs.

However, solar energy is super unstable since it is influenced by geography, weather, and topography, relying on the storage system.

Traditionally, electrochemical batteries are the house for solar energy. As solar power is pumped into the battery, a chemical reaction among the battery parts saves energy. The reaction will be overturned when discharging the battery, enabling the current to exit the battery.

But the chemical reactions have their issues. For example, the battery’s lifespan will drop after times of charge and power release. Therefore, ultracapacitor-based energy storage can be a problem-solver. 

Things You Should Know About Ultracapacitor

In this part, you can have some knowledge of ultracapacitors: what is it, their advantages, and how can they help with the solar energy development. 

• What is Ultracapacitor?

An ultracapacitor, or supercapacitor, is an electrochemical energy storage device that stores and releases energy by reversible adsorption and desorption of ions at the interfaces between electrode materials and electrolytes. Its performance is between the chemical battery and the static capacitor but adsorb their features.

Precisely, it is a high-capacity capacitor with a capacitance value much higher than other capacitors but with lower voltage limits that bridge the gap between electrolytic capacitors and rechargeable batteries. Typically, it stores more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.

The ultracapacitor sticks out from other electric storage devices because of its higher power density and longer cycle lifespan. It is able to optimize the speed and endurance because, like batteries, they use ions and an electrolyte rather than simply relying on the static charges.

• The advantages of Ultracapactiror

Compared with the traditional capacitor, the advantages of the ultracapacitor are listed below:

1. Higher power density: it can reach 102 to 104 kW/kg, far exceeding the chemical batteries.
2. Longer cycling lifespan: the capacity and power resistance only decrease by 10 to 20% after experiencing 500 thousand to 1 million times of high-speed power charging and releasing. The changes in its characteristics are negligible.
3. Resistance to extreme temperature: ultracapacitor can deliver great performance even in harsh environments. It can work well in the temperature between -40oC to 80oC
4. No maintenance: ultracapacitor has greater power charging and releasing efficiency and can uphold the pressure generated during the process. Theoretically, no maintenance is needed.
5. Environmental-friendly: no heavy metal and toxic chemical substances will be emitted when processing; on top of them is its long lifespan, meaning fewer fixing and replacing.

Conclusion

The sun is a powerful energy source. The sunlight is by far the largest energy source received by Earth-- about 200,000 times the world’s total electric-generating capacity is received by Earth every day in the form of solar energy. Through this, we can tell the great potential of the energy and the importance of ultracapacitor.
