DOOHYUN POWER Technology is:

The current world will bring about a rapid change from secondary batteries to the era of supercapacitors in the future as the material industry advances along with new energy storage technologies, and it is certain that the best way to protect the Earth's environment is the energy storage device of the "supercapacitor.

"Starting with the development of secondary batteries for about 10 years, DOOHYUN POWER Technology developed Super Capacitor, an eco-friendly energy storage technology that is essential for human eco-friendly life safe from explosions and fires. 

It succeeded in commercializing various prototypes equipped with protective circuits and is preparing mass production to supply them under contracts with Korea and foreign countries.

Energy has been constantly changing from fossil to petroleum, nuclear power, solar power, and wind power, and now focuses on eco-friendly electrical energy and hopes to supply many products not only in Korea but also abroad with the energy storage device of the "super capacitor" we developed.

Ultracapacitors are highly efficient devices.

Since the Coulomb efficiency (dividing the total amount of charge discharged by the total amount of charge added to fill the amount of charge discharged) exceeds 99% even at high currents, there is little charge lost when charging and discharging the ultracapacitor.

In addition, Round-Trip Efficiency (RTE) is also very high thanks to low Equivalent Series Resistance (ESR).

Within 5 seconds, RTÉ exceeds 70%. Within 10 seconds, RTÉ exceeds 80%.

This not only makes more efficient use of energy, but also prevents overheating.

Therefore, there is a high possibility that the overhead of cooling the energy storage device will be reduced.

Discharge to 1/2 voltage in 5 seconds and charge at the same rate until the ultracapacitor is fully charged.

※ The main raw material used for capacitors uses activated carbon called graphene.

By using activated carbon, it is very eco-friendly, has a very long life, and can charge and discharge from tens of thousands to millions.

Supercapacitor? ~

Understanding supercapacitors:

A typical secondary battery uses an electrochemical reaction.However, a super capacitor is an energy storage device that can adjust fast charging and discharging time without risk of explosion fire using a method of physically storing electric charges themselves and obtain long life and high energy density.

supercapacitor principle

The principle of supercapacitor is the principle of charging or discharging energy by physical adsorption or desorption of electric charges on the surface of activated carbon, which refers to a high-power power source that instantly stores a lot of energy and then supplies a high current instantaneously or continuously.

The super capacitor uses activated carbon (~3000 m2/g) with an increased specific surface area per unit weight as an electrode material, resulting in a dramatic increase in capacity.

We will constantly study based on our experiences through numerous failures.

The trend of renewable energy continues to evolve.
From fossil to petroleum to nuclear power and renewable wind power, energy has been constantly changing. Large-scale, more power is being built, and the production capacity of electrical energy is becoming a measure of a country's status.

With the goal of meeting the needs of the times, we are constantly researching ways to store energy and developing more advanced energy storage technologies based on our experience with numerous failures.

The smartest way to store energy is through supercapacitors, and we will produce a variety of energy storage devices using them.
Energy storage devices that are faster, have a longer lifespan, but also consider the health of the Earth's environment will become supercapacitors.

With the development of the materials industry along with the new energy storage technology we have, we believe that the best way to protect the Earth's environment is to store energy in supercapacitors, which will bring about a drastic change from secondary batteries to the era of supercapacitors.

If you want more information, we would appreciate it, and we will provide you as much as we can.
Would you be a global partner to be with our vision in many ways?

Thank you.
